Seed Market Concentrates Funding Among Few Startups

Carta's State of Seed Stage 2025 and a16z's Speedrun show that in 2025 half of venture capital went to the top 1% of startups, driven largely by generative-AI companies. Median seed cash is about $3.6M, average seed teams are 6.2 employees, and time to Series A has lengthened to roughly 2.1 years (Israel ~35 months). This concentrates capital and raises hiring and runway pressures.
Key Points
- 1Shows funding concentration: 50% of 2025 VC went to the top 1% of companies
- 2Drives mega-seed rounds, pushing median seed cash to $3.6M and fewer total rounds
- 3For founders: adopt post-money SAFEs, expect ~20% dilution, plan longer runways
