131+ Seed AI Startups — 66 Companies Raised $1.9B

Seed-stage AI funding in 2025-2026 has created a new category: the AI mega-seed. Our dataset tracks 66 seed AI companies that raised a combined $1.9B at a $6M median — 50% above the overall seed median of $4M. Some AI companies have raised $30-60M seed rounds — amounts that would have constituted a strong Series A just two years ago. With 66 companies, seed AI represents the single largest stage-industry cohort in our entire dataset, underscoring the sheer volume of AI company formation. The most active seed-stage AI investors include Y Combinator, Sequoia Scout, and a16z SPEEDRUN. Companies raising AI seeds typically have technical founding teams with deep ML research backgrounds, often from leading labs. For sales teams, these 66 companies are early-relationship prospects making foundational technology decisions (cloud provider, dev tools, monitoring) that will persist through their growth stages. The $1.9B total means significant aggregate purchasing power even at the seed stage. The window for vendor lock-in is narrow — reach out within 30 days of funding to establish mindshare.
