The generative AI funding landscape has evolved dramatically in 2025, with Series A rounds becoming increasingly competitive and selective. While the market continues to show strong investor interest in AI companies, founders need a data-driven approach to identify which funds are actively writing checks and what traction milestones they demand. (Metal Intelligence)
This comprehensive guide analyzes the most significant Series A deals in generative AI from Q1-Q2 2025, identifies the key investors leading these rounds, and provides a systematic approach to targeting the right funds for your AI startup.
The first half of 2025 has seen several landmark Series A rounds that demonstrate continued investor appetite for generative AI companies. Genesis AI's massive $105 million seed round, co-led by Eclipse and Khosla Ventures, signals strong institutional interest in AI applications for robotics. (TechCrunch) While technically a seed round, the size and investor profile mirror what we typically see in Series A deals.
The company, founded by Zhou Xian (PhD in robotics from Carnegie Mellon) and Théophile Gervet (former Mistral research scientist), aims to build a general-purpose model enabling robots to automate repetitive tasks from lab work to housekeeping. (TechCrunch) This deal exemplifies the type of ambitious, well-credentialed teams that top-tier VCs are backing in the generative AI space.
Meanwhile, established players like Stability AI continue to innovate with new model releases like Stable Diffusion 3.5 for professional-grade image generation, demonstrating the ongoing evolution and commercial viability of generative AI applications. (Stability AI)
The U.S. venture capital industry experienced a record-breaking boom in 2021, followed by a reset during 2022-2023, and is now finding a new equilibrium. (Medium) This normalization has created a more selective environment where investors are focusing on companies with clear traction and differentiated technology.
For Series A rounds specifically, most are led by well-known institutional investors with significant investment experience. (Metal Series A Overview) The market for Series A financing has been particularly challenging since the 2022 downturn, making it crucial for founders to target the right investors with precision.
Based on recent deal activity and investment patterns, several funds have emerged as consistent leaders in generative AI Series A rounds:
Eclipse Ventures has demonstrated strong conviction in AI applications, co-leading Genesis AI's large seed round. Their focus on applied AI and robotics makes them a prime target for founders building practical AI solutions.
Khosla Ventures continues to concentrate investments in emerging technologies, with 27% of their portfolio in healthcare and significant activity in AI applications. (Metal Finding Investors) Their thesis-driven approach and willingness to lead large rounds makes them attractive for ambitious AI companies.
First Round Capital tends to invest early but specializes at the seed stage, making them "seed specialists" rather than "pre-seed tourists." (Metal Finding Investors) For companies transitioning from seed to Series A, understanding this distinction is crucial.
Only about 10% of all venture funds are actively deploying capital at any given time. (Metal Finding Investors) Founders need to filter for investment firms that have made at least one investment in the past 3-6 months to ensure they're targeting active deployers.
The key is focusing on investors that are "geographically relevant" based on their prior investments, rather than taking an overly restrictive approach. (Metal Finding Investors) Many European and Asian investors actively invest in US AI companies, expanding the potential pool significantly.
Metal's platform enables founders to create highly targeted investor lists using granular filters. (Metal Investor Search) For generative AI Series A targeting, the optimal filter combination includes:
Stage Filtering: Focus on "stage specialists" rather than "stage tourists" by filtering for investors who have made at least 25% of their investments at Series A. (Metal Stage Filters) This ensures you're targeting funds that truly understand Series A dynamics and expectations.
Sector Concentration: Look for investors with both "sector familiarity" and "sector concentration" in AI/ML. (Metal Finding Investors) Familiarity means they've made multiple AI investments; concentration means a significant percentage of their portfolio is in AI, indicating a strong thesis.
Recent Activity: Filter for funds that have made investments in the last 6 months to ensure active deployment. (Metal Other Filters) This eliminates "barely active" funds that make only 1-2 investments annually.
Fund Size Alignment: Target funds with $100-500M in assets under management, as they typically write $2-10M checks suitable for Series A rounds. (Metal Finding Investors) The general rule is that investors maintain check sizes of roughly 1-2% of total fund size.
Here's how to set up a dynamic list in Metal for generative AI Series A targeting:
Sector: Artificial Intelligence/Machine Learning
Stage: Series A (minimum 25% of investments)
Last Investment: ≤ 6 months
Fund Size: $100M - $500M
Geography: North America + International (US-focused)
Lead Percentage: ≥ 20% (to identify potential leads)
This filter combination typically yields 50-100 highly qualified prospects, allowing for focused outreach rather than spray-and-pray approaches. (Metal Quickstart)
At Series A, investors evaluate opportunities based on growth and traction metrics. (Metal Series A Overview) For generative AI companies, the specific benchmarks vary by business model:
SaaS AI Tools: Companies have successfully raised Series A rounds with $0.5-1M in annualized run rate, provided they show 100-150% year-over-year growth. (Metal Series A Overview) On the upper end, companies with $3-3.5M ARR and 500%+ growth have commanded premium valuations.
API/Infrastructure Plays: Focus on usage metrics, API calls per month, and developer adoption rates. Monthly active developers and revenue per API call are key indicators investors examine.
Enterprise AI Solutions: Contracted revenue, pilot-to-paid conversion rates, and expansion revenue from existing customers demonstrate product-market fit in enterprise segments.
Beyond financial metrics, generative AI companies need to demonstrate:
Model Performance: Benchmark results against established models, accuracy improvements, and inference speed optimizations.
Scalability Proof Points: Evidence that the technology can handle increased load and maintain performance at scale.
Differentiation: Clear technical moats, proprietary datasets, or novel architectures that create sustainable competitive advantages.
Before pursuing any investor, founders need to run a rigorous qualifying process to ensure strong fit. (Metal Finding Investors) For each target investor, examine:
• Track record of leading rounds: Do they have experience leading Series A deals?
• Sector investment history: Have they invested in generative AI or adjacent spaces?
• Recent activity: Are they actively deploying capital in current quarters?
• Competitive conflicts: Do they have portfolio companies that might conflict?
• Stage appropriateness: Are they truly Series A specialists?
The prior investment patterns of a fund are the biggest indicator of their inclination for a given stage, sector, or geography. (Metal Intelligence)
Cold email outreach has evolved significantly, with relevance and trustworthiness becoming the primary factors determining success in 2025. (Hunter) In 2022, 54.4% of survey respondents stated that cold email was getting harder, making precision targeting even more critical.
Purpose Built's analysis of 41,209 cold emails across 193 experiments achieved a 3.8% positive engagement rate, demonstrating that systematic approaches can work. (Purpose Built)
Lead with a specific insight about their portfolio or recent investments. Reference a recent AI deal they've done and explain how your company addresses a related but distinct opportunity.
Share a meaningful milestone or customer win that demonstrates momentum. Include specific metrics that align with Series A expectations.
Leverage Metal's network mapping to identify mutual connections who can provide warm introductions. (
AI can supercharge outreach by personalizing pitches and optimizing interactions. (StepUp) AI tools can act as analyst, strategist, and workhorse, helping to sift through investor databases and craft targeted outreach strategies.
However, the key is maintaining authenticity while using AI for efficiency. The best outreach combines AI-powered research with genuine, personalized insights about the investor's interests and portfolio.
The best decks don't just tell your story - they teach something new and make your strategy feel both unique and inevitable. (Metal Intelligence) For generative AI companies, this means educating investors about:
• Market Timing: Why now is the right time for your specific AI application
• Technical Moats: What makes your approach defensible and scalable
• Go-to-Market Strategy: How you'll capture and expand market share
1. Problem Definition: Frame the specific inefficiency or opportunity your AI addresses
2. Solution Architecture: High-level technical approach without getting too deep into the weeds
3. Market Size and Timing: TAM/SAM/SOM with focus on market readiness for AI adoption
4. Traction and Metrics: Revenue, usage, and growth metrics that matter for your business model
5. Competitive Landscape: How you differentiate from both AI-native and traditional solutions
6. Team and Advisors: Highlight AI/ML expertise and relevant domain experience
7. Financial Projections: 3-year revenue forecast with key assumptions
8. Funding Ask and Use of Funds: Specific allocation for talent, infrastructure, and growth
Typical fundraising targets around 200 investors, with expected outcomes of one-third not responding, one-third passing without a call, and one-third agreeing to first meetings. (Metal Intelligence) This means having 10-15 genuinely excited investors requires around 70 first calls.
For Series A specifically, the biggest challenge is finding a lead investor who can then coalesce other investors into the round. (Metal Series A Overview) Less than 10% of all venture investors tend to lead rounds, making lead identification crucial.
Series A processes typically take 3-6 months from initial outreach to closing. Key milestones include:
Using Metal's built-in CRM helps manage and track fundraising outreach from start to finish. (Metal Intelligence) The platform enables founders to avoid common pitfalls in conventional fundraising by bringing efficiency, structure, and intelligence to the process.
A stage mismatch is among the most common reasons investment discussions don't result in positive decisions. (Metal Series A Overview) Many founders pursue seed-stage investors for Series A rounds or engage with pre-seed investors when they need larger checks.
Founders raising large rounds need to target VCs with appropriate fund sizes. (Metal Finding Investors) A fund size mismatch is often a primary reason investors can't lead or participate in rounds, regardless of their interest level.
A common pitfall is engaging non-lead investors in a Series A process before securing a lead. (Metal Series A Overview) The data shows far more investors participate in Series A rounds than lead them, making lead identification the critical first step.
Generative AI companies face unique technical due diligence requirements:
Model Architecture Review: Investors often bring in technical advisors to evaluate model design, training approaches, and scalability considerations.
Data Strategy Assessment: Questions about training data sources, data quality, and ongoing data acquisition strategies.
Compute Cost Analysis: Understanding of inference costs, model optimization, and path to profitability given compute requirements.
Investors increasingly evaluate AI companies on:
Safety and Alignment: Approaches to ensuring model safety and alignment with intended use cases.
Bias and Fairness: Strategies for identifying and mitigating bias in model outputs.
Privacy and Security: Data handling practices and security measures for sensitive information.
Series A investors typically join boards and become long-term partners. Evaluate potential investors on:
Network Access: Can they help with customer introductions, partnership opportunities, and talent recruitment?
Technical Expertise: Do they have portfolio companies or advisors who can provide technical guidance?
Follow-On Capacity: Will they be able to participate in future rounds as the company scales?
Series A rounds should position companies for successful Series B raises 18-24 months later. This means:
Milestone Planning: Clear objectives that will qualify the company for the next stage. (Metal Series A Overview)
Investor Syndicate Building: Bringing in investors who can lead or significantly participate in Series B rounds.
Market Positioning: Establishing clear market leadership in a defined category or use case.
The generative AI Series A landscape in 2025 rewards founders who take a systematic, data-driven approach to investor targeting. By focusing on stage specialists with sector concentration and recent activity, founders can significantly improve their conversion rates at every step of the fundraising funnel. (Metal Finding Investors)
The key is combining Metal's intelligent filtering capabilities with thorough research and personalized outreach. (Metal Intelligence) Remember that the prior investment patterns of a fund are the biggest indicator of their inclination for your stage, sector, and geography.
For generative AI founders, success requires demonstrating not just technical innovation but clear paths to scalable revenue and defensible market positions. The investors writing Series A checks in 2025 are looking for companies that can navigate both the opportunities and challenges of the AI revolution while building sustainable, profitable businesses.
By following this systematic approach to investor identification, qualification, and outreach, generative AI founders can position themselves for successful Series A raises even in today's competitive funding environment. The data shows that targeted, intelligent fundraising approaches consistently outperform spray-and-pray tactics, making tools like Metal's dynamic investor lists essential for modern fundraising success.
Based on Metal's empirical analysis of Series A deals, investors typically look for strong product-market fit indicators, recurring revenue growth, and proven AI model performance metrics. The competitive landscape in 2025 has raised the bar significantly, with funds demanding clearer monetization paths and defensible AI capabilities before writing checks.
Eclipse and Khosla Ventures have been particularly active, co-leading Genesis AI's $105M seed round for robotics AI models. Other key players include funds focusing on foundational AI models and specialized applications. The research shows that investors are increasingly selective, favoring companies with clear use cases and proven technical differentiation.
Metal Intelligence provides data-driven insights into investor behavior and deal patterns, helping founders identify funds that have previously invested in similar companies. The platform's empirical overview of Series A deals reveals which investors are actively writing checks and what criteria they use for evaluation, enabling more targeted outreach strategies.
According to recent research, relevance and trustworthiness are the primary factors determining email outreach success in 2025. With 54.4% of respondents stating that cold email is getting harder, founders need AI-powered personalization and data-driven targeting. The most successful campaigns achieve 3.8% positive engagement rates through systematic experimentation and optimization.
The 2025 landscape shows increased selectivity following the 2021 boom and 2022-2023 reset period. While investor interest remains strong, as evidenced by large rounds like Genesis AI's $105M seed, funds are demanding higher traction thresholds and clearer paths to profitability. The market has found a "new equilibrium" with more rigorous due diligence processes.
AI acts as an analyst, strategist, and workhorse in modern fundraising, handling tasks like sifting through investor databases, crafting personalized outreach, and automating repetitive processes. AI-powered tools can supercharge outreach effectiveness, predict investor behavior, and optimize pitch timing, making the fundraising process more efficient and data-driven for generative AI startups.

Our team has had the benefit of observing a large number of early-stage founders, as they embarked on their journeys to build access with investors. In the below post, we have documented our observations around the most common access points.
In the earliest stages of company-building, founders generally find it a lot easier to establish relationships with other VC-backed founders, and then use these relationships to get introductions to investors. We have observed founder networks to play a central role in successful raise processes, irrespective of the stage.

When building a strong network of other VC-backed founders, users have reported the most success with the following strategies:
When building access via founder networks, users are able to get a useful perspective on the investing personalities of various investors directly from founders that have raised from them. Based on feedback from our customer base, we have observed this insight to be even more useful than the introduction itself.
Your existing investors are heavily incentivised to help you raise your next round. The ability of founders to mobilise the support of existing investors is a learned skill. The below guidelines can serve as a useful starting point:
For most founders, their existing or current cap table is one of the most critical assets in a raise process. Founders that successfully close rounds tend to be most effective in getting the most value of our their existing cap table.
Pre-Seed investors routinely invest in companies in the pre-product and pre-revenue stages. With this write-up, we look to bring clarity and precision around what investors look for at this stage.
At Pre-Seed, investors are often investing at a median valuation of $4m. Given the low entry price, Pre-Seed investors end up doing well as long as the Company is able to develop a reasonably strong product.
Put differently, the factors associated with whether or not the Company grows to a multi-billion dollar enterprise may not be super relevant for Pre-Seed investors. If the Company builds a strong product, and even if the Company is not wildly successful, Pre-Seed investors will still do fairly well.
Investor X invests $500K in the Pre-Seed round of Company Y at a 4m post-money valuation. Let's assume that the Company succeeds in building a reasonably strong product, but is ultimately unable to scale. The Company ends up selling for $18m (without raising subsequent venture rounds). Pre-Seed investors end up realising a 4.5x return on the original investment.
While there are broad variations in how Pre-Seed investors look at companies, a common theme is a clear focus on the founder's ability to build a strong product. How, then, do investors assess whether or not a founding team will succeed at building a strong product?
At Pre-Seed, the main bet is on the founder's ability to build a great product. Investor discussions are, therefore, focused heavily on developing an assessment on whether or not a given founder will be able to build a great product.
Of all venture stages, Series A shows the steepest drop-off point. Specifically, of all companies that raised Seed rounds in the five-year period from 2015 to 2020, only 45% successfully raised Series A.
The most common cause of drop-off is simply company performance. Most companies are unable to achieve the growth metrics that are typically required for Series A.
For companies that hit exciting performance milestones, a sizeable drop-off stems from an inability to work capital markets. In Robotics or Consumer, for instance, raising capital has historically been much harder than for B2B SaaS or Fintech. Relative to the Seed landscape, we believe Series A is distinct in the following ways.
In how founders manage their financing strategy, Series A rounds generally require a lot more sophistication than do seed rounds. From targeting to process, and from narrative to collateral, the general skill set required at Series A is fundamentally different from prior rounds.
Instead of relying on hearsay, founders across the board are now taking an empirical approach to raising their next round. At Metal, we are seeing customers use our platform in novel ways to discover the “most likely” partners for their company and round construct.
Before pursuing an investor, founders need to run a “qualifying process” to ensure that the prospective partner is a strong fit. A rigorous process to identify, research and qualify investors is the highest leverage activity within fundraising, one that improves conversion rates.
The below post focuses exclusively on identifying the “most likely” investors, and does not cover the qualifying process. In the identification process, there are six core principles at play.
Founders often confuse pre-seed and seed investors as one and the same. The common perception is that these are just stage names that do not carry much significance. In reality, investors have vastly different expectations at preseed versus at seed, and most investors that specialize at seed do not specialize at pre-seed. Readers that are looking to understand investor expectations at each stage can read more here.
First Round tends to invest early, but they are really seed-stage investors, and not pre-seed partners. Since they specialize at the seed stage, they are “seed specialists” and “pre-seed tourists”.
By definition, stage specialists are investors that specialize in a given stage. Stage tourists are ones that invest in that stage opportunistically in outlier or unique opportunities.
The first challenge for founders is to identify a set of “stage specialists” for their specific stage. This is easily achievable by filtering investors based on the percentage of investments that they have made in a given stage. The key thing is to not settle for ambiguous tags applied to investors in the absence of any underlying data.
For venture investments, the landscape varies substantially from one sector to another. Some sectors have very strong and ongoing venture activity (I.e. B2B Software) while others have fewer investments in total (I.e. Industrials or Robotics).
For any given sector, there are two types of investors –
Investors that fall in the (1) category can be identified using a simple filter that identifies all investors that have made a minimum number of investments in a given sector. Investors that fall in the (2) category can be identified by filtering for investors that have made a minimum percentage of investments in a given sector.
Investors that are familiar with a given sector are those that have previously invested in that space and are familiar with it. Investors that are concentrating in a given sector typically have a strong thesis for that opportunity space and may sometimes be stronger partners.
As an example, Khosla Ventures is a well-known VC firm that has been concentrating investments in the healthcare sector. To date, they have made 27% of all investments within healthcare. Within healthcare, about half of all investments are in two specific sub-sectors: Drug Discovery (24%) and Therapeutics (29%).
It is fairly likely that Khosla has a clear and strong thesis in these sub-sectors, which may sometimes make them a particularly strong partner for healthcare companies building in these spaces.
Finally, at the pre-seed stage, most investors tend to be sector agnostic. This is primarily due to the investment model of venture investors at the pre-seed stage.
Most users are either overly restrictive by focusing on only those investors that are based in their specific country, or are too liberal and end up pursuing investors that don’t focus on their geography.
The key thing is to identify investors that are “geographically relevant” based on their prior investments. This is typically different from taking an overly restrictive approach whereby users are focusing only on those investors that are based in their country or region.
Founders raising large rounds need to target a small set of VCs that have large fund sizes. For such founders, the options are fairly limited (as there is a very limited number of VCs with a fund size of $500m+). On the contrary, founders looking to add a small amount of capital ($<1m) to an existing round need to target micro VCs that write $100-300K follow-on checks.
The general rule of thumb is that most investors maintain a check size that is roughly 1-2% of the total fund size. As an example, investors with a fund size of $100M will typically write checks in the $100-200K range.
Depending on the round dynamics, founders can focus on investors that have a fund size that meets their round requirements. A fund size mismatch is often a primary reason for why investors are unable to lead or participate in rounds.
Similar to startups, venture funds tend to have a fluid nature. At any given point in time, only 10% of all venture funds are actively deploying capital. Founders, therefore, need to filter for and focus on investment firms that have made at least “1” investment in the past 3 or 6 months.
It is extremely common for founders to learn after a few calls that the fund is “barely active”, making only one or two investments each year. For funds that are operating in a “barely active” mode, the overall risk appetite is unique. Such funds will have behaviors that are a lot less predictable than ones that are actively and consistently deploying capital.
Early on in the process of raising a round, founders need to first identify an “anchor” investor to lead the round. While most funds lead occasionally, there is a fairly limited pool of investors that frequently lead rounds, and that do not wait for a lead to come in before committing to invest.
When starting a round, founders need to focus on investors that have a history of leading. This is easiest to identify by looking at the percentage of investments that a given investor has historically led.
In summary, the six core principles defined above help build a clear criteria for the sort of round that founders want to raise. Based on the round requirements, founders then need to run a rigorous process to identify the right set of “most likely” investors. By targeting their efforts on the right set of investors, founders can significantly increase conversion rates at every step of the fundraising funnel.
In a given raise process, the type of investors that founders pursue varies broadly based on the context of the round. Are you looking to raise on the back of sustained growth and traction, or are you yet to see traction? Are you looking for a lead investor, or are you instead seeking a party round with a lot of small investors?
In the below post, we explain how founders can go about forming an empirical criteria to zoom in on the right type of investors for the round.
For purposes of the below example, let's assume that the founder is raising a $12m Series A round for a "Buy Now, Pay Later" company that operates in the Fintech sector and is based in the US. In this specific scenario, the founder will need a lead investor to put the round together.
Conceptually, founders should distinguish between attributes that serve as qualifications versus ones that work as disqualifications. The above list shows a list of factors that should serve as disqualifications. If an investor does not meet the above criteria, then they probably should not be on our target list. The specific thresholds can be adjusted based on our preferred levels of flexibility or rigidity.
After closely observing thousands of raise processes, we find that a vast majority of founders end up targeting and pursuing investors that aren't a great fit for their Company. In the absence of a data-driven process, it can be challenging to identify the right investors.
On the contrary, targeting the right investors leads to:
It takes time and effort to take a super targeted approach (versus just getting on calls with whichever investors can be easily accessed). At Metal, we view the time and effort invested on this front as the highest leverage activity in a raise process.
