YC can't predict which companies become outliers, but the strongest observable signal of a team on track is continuous week-to-week progress: at each office hour there's genuinely new, exciting movement rather than a rehash of two weeks ago. Vanity signals — being in a hot industry, press coverage, investor interest — are uncorrelated with outlier success. The right response to uncertainty is to help teams avoid the well-known failure modes rather than to try to pick winners.
Origin
Gustaf Alströmer's synthesis from 600+ YC companies; echoes Paul Graham and Jessica Livingston's early observation that consistently hitting goals correlates with success.
Core principles
- 01No one can reliably pick outlier winners at the seed stage; outliers succeed for reasons that are unknown and counterintuitive
- 02What's knowable is what failure looks like — so steer teams away from known failure modes
- 03Continuous progress on a weekly/biweekly scale strongly correlates with success
- 04Being in a hot market, press, or investor attention are uncorrelated with outlier outcomes
How to run it
- 1
Stop trying to pick winners
Accept that identifying the outlier is not possible at the seed stage; the best teams may share known attributes but what makes them outliers is unknown.
Watch out Chasing 'which one is the next Airbnb' wastes energy on an unanswerable question.

Coach teams away from known failure modes
Be direct and honest: name the specific things a team is doing that have caused failure before (not talking to customers, building everything at once).
Pro tip Tell strong teams: if you fail, do it in a new way we haven't seen 100 times.
- 3
Track new progress at each check-in
At each recurring meeting, look for genuinely new movement — new customers closed, new conversations, evolved pricing — versus a rehash of the last session's topics.
Pro tip A team that's already done what you'd suggest and moved two steps beyond is showing the ~10% weekly growth pattern.

Discount vanity signals
Weight rapid week-to-week progress far above 'hot market,' press mentions, or investor interest, which don't predict outlier success.
Watch out Founders confuse external validation (press, investor interest) with product-market fit; it isn't.
In the wild
A team that two weeks ago was trying to sell to three customers returns having already closed them, now talking to seven more at a different price and product tier because customers want more. That consistent trend is what YC attributes the steep weekly-growth revenue curve to.
→ Consistent short-cycle progress became the reliable indicator of a team on track, far more predictive than market or investor signals.
Common mistakes
Mistaking external validation for traction
Founders treat investor interest, press, and a hot market as proof of product-market fit; these are uncorrelated with outlier success and mask the absence of real progress.
Trying to predict the outlier instead of preventing failure
Since outliers succeed for unknown reasons, effort spent picking winners is wasted; the leverage is in stopping teams from repeating known failure modes.
Is it for you?
Best for
Investors, accelerators, and founders who want an honest signal of whether a team is on track
Not ideal for
Contexts demanding confident early prediction of which specific company will be the breakout winner
From the transcript
“we're not not very good at knowing what's going to succeed”
“if each new office hour there is really exciting new stuff right we're not talking about the same thing we talked about two weeks ago”
“progress on this like weekly or bi-weekly time scale is a really good indicator of someone who succeed”
“people confuse this external validation with the thing that matters the most which is talking to customers”
