Market Context and Investor Behavior
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.
Key Investors Leading Generative AI Series A Rounds
Tier 1 Institutional Leaders
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.
Identifying Active Funds
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.
Building Your Target List with Metal's Dynamic Filtering
Setting Up Your Generative AI Series A Filter
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.
Creating Your Dynamic List
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)
Traction Milestones That Matter
Revenue and Growth Benchmarks
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.
Technical and Product Milestones
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.
The Outreach Playbook
Pre-Outreach Research and Qualification
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)
Crafting Your Initial Outreach
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.
