Y Combinator

TL;DR

It creates resource-sharing networks that function like underground fungal systems.

Venture Capital / Startup Accelerator · Founded 2005

Y Combinator doesn't just fund startups. It creates resource-sharing networks that function like underground fungal systems. While the financial terms weren't revolutionary ($500,000 for 7% equity), the symbiotic insight was: connect 300+ companies per batch so intensely that they become a living network. Founders share office space, critique products, exchange technical solutions, introduce customers, and hire from each other's talent pools.

The model is 'germination factory' - mass germination with harsh early selection. YC provides weekly office hours, peer support, forced rapid iteration, and Demo Day as a 'light gap' for investor attention. Their data shows ~50% fail, ~25% become small businesses, ~20% return capital, and ~5% become large successes. But the survivors don't just succeed - they become resource providers. Large 'trees' like Stripe, Airbnb, DoorDash, and Coinbase send resources through the network to struggling 'seedlings.'

The cooperation is enforced through reputation (founders who don't help get excluded) and iterated interactions (you'll see these people again). When COVID hit, YC companies shared PPP loan information and remote tools faster than formal communications could deliver. YC companies are significantly more likely to reach Series A than comparable non-YC startups. The lesson: networks beat capital. The $500,000 check matters less than 299 other founders who understand your problems.
