Y Combinator - Batch Analysis

YC's Last
3 Years

7 batches. ~1,800 companies. One that changed everything.

414 W22 companies

90+ from W22 never made it. Dead. Pivoted. Abandoned.

Act I

W22 was YC's
biggest bet ever.

414 companies. 50% international founders. The first batch with a $500K standard deal. YC had never been more ambitious, or more exposed.

Then the funding winter hit. Then interest rates climbed. Then the market decided it had no patience for early-stage experiments with no path to revenue.

56%
of VC-backed startups that failed in 2024 were from 2022 cohorts. W22 is over-represented.

That dot grid to the left: each dot is a company. The grey ones never made it.

Act II

Then GPT-4 launched.
Everything changed in one application cycle.

GPT-4 released: March 14, 2023

Between S22 and S23, the AI share of YC went from 15% to 57%. Not a gradual shift. A detonation.

Founders who submitted S23 applications had seen GPT-4. Founders who submitted S22 applications had not. That one release date is the dividing line between two completely different YC eras.

+280%
Growth in AI company share from S22 to S23. One application cycle. One model launch.
Interlude

YC quietly became
a Bay Area club.

W22 had 50% international founders. By W25, that number had collapsed to 10%. Garry Tan took over, reversed the pandemic-era global experiment, and rebuilt YC around physical presence in San Francisco.

-80%
Decline in international founder share: W22 (50%) to W25 (10%).

"The world's accelerator became a zip code."

Act III

One dot worth more than
everything from W22 combined.

Cursor graduated from W23. Today it is worth $29.3 billion. The entire W22 batch, all 414 companies, cannot match it.

This is not a YC success story. It is a YC outlier story. The returns are not distributed. They are concentrated in one or two founders who were right about which specific layer of AI would matter, before it was obvious.

Cursor valuation - W23 batch - YC's greatest outcome in this era

Note: Perplexity AI is frequently misattributed to YC. It is not a YC company. The W23 story belongs to Cursor alone.

Synthesis

Being right early on category
beats execution. Every time.

Cursor did not win because it was the best-executed AI coding tool. It won because it was the earliest credible one, from a team with the right technical depth, at the moment the category was forming.

The founders who won from W22-W25 understood which specific layer of AI would matter before that layer was confirmed.

Pattern 01
Infrastructure beats application - the best companies built layers, not features
Pattern 02
Speed to Series A equals survival - AI companies raise 30-50% faster than non-AI peers
Pattern 03
Batch size down, quality up - 414 companies (W22) to 160 (W25), better outcomes per cohort
