666+ Seed Funded Startups — 354 Companies, $3.8B Raised

Seed funding in the 2025-2026 window is the highest-volume stage by far, with 354 companies raising a combined $3.8B at a median round size of $4M. The landscape shows clear bifurcation: AI-focused seed rounds (66 companies, $1.9B total, $6M median) regularly reach $10-30M — territory traditionally reserved for Series A. Meanwhile, non-AI verticals are raising more modest rounds with greater emphasis on capital efficiency. SaaS seed rounds (37 companies, $402M, $4M median) and FinTech seeds (31 companies, $414M, $4M median) cluster tightly around the $4M mark. Y Combinator, Techstars, and a16z SPEEDRUN continue to be the most prolific seed-stage investors, while solo GPs and micro-funds are increasingly competitive in niche verticals. Geographic distribution mirrors the broader dataset — the US dominates, but UK and European founders are well-represented in climate and SaaS seed rounds. For SDRs and agencies, seed-stage companies represent early relationship-building opportunities. While their budgets are smaller ($4M median vs. $21M at Series A), founders making technology decisions at seed stage become long-term customers. The key metric to watch is team size — seed companies with 10-25 employees are actively purchasing their first software tools and establishing vendor relationships that persist through growth stages.
