One accelerator has backed 1 in 5 of the world's most valuable startups started since 2012. We think that is the single most concentrated, repeatable source of venture returns on earth, and we built Lobster to invest in nothing else.
Y Combinator invests $500K into each company it picks, then spends three intensive months helping it launch. It's the output of a 20-year-calibrated filter: 27,000+ applications per batch, about 1% accepted, a 10-minute interview backed by two decades of pattern data. The best founders chase YC, which produces more breakouts, which pulls in more top founders, a compounding structural advantage no new program can buy.
YC alumni carry a combined valuation over $1.3T, with 120+ companies valued above $1B and 400+ above $100M. Its unicorn rate runs about 6.5% versus a 1% industry average. Garry Tan, YC's CEO, has said 45% of YC companies reach Series A with median ARR over $1M, and 87% of YC companies are still operating, versus roughly 50% startup survival after five years.
Data shows unicorns are a tiny share of YC companies but about 90% of all portfolio value growth. Airbnb went through YC at a roughly $20M seed valuation and hit $100B at IPO. Early seed investors in Airbnb, Stripe, Dropbox, Instacart, and DoorDash generated 1,000x+ returns. The lesson is not "avoid YC because most companies fail," it is "be in the pool that produces the most outliers, and be selective inside it."
Most capital chases the same demo-day list. We don't. We concentrate on the rare companies showing real traction, a credible path to efficient scale, and founders who compound, and we pass on everything else. Three filters: customers who clearly love the product, a path to efficient scale, and exceptional founders with unique insight. A company has to clear all three.
Roughly two-thirds of recent batches are building with AI, and these companies reach revenue faster and more capital-efficiently than any prior cohort. That means earlier, more attractive entry points into companies compounding at unprecedented speed, exactly when disciplined, well-connected access matters most.
Y Combinator funds the companies most likely to define the next decade. We exist to put serious allocators inside that exact lane, with the discipline to take only the best of it.
We back Y Combinator companies exclusively. A decade inside the network means we know the partners, the patterns, and the founders worth backing before the round is competitive.

Allocators rarely see the YC deals that matter. As an LP in Lobster, you hold a single, disciplined line into the world's most valuable startup ecosystem.
