He says:

"For instance, if you are pitching a research lab without a specific plan to profitability (e.g. Mistral AI), then YC is not for you. "

So does YC fund similar companies [with "better" founders]?

This post reminds me of a founder I worked for. We had a pitch meeting where one of the prospective investors laid out exactly why the founder’s idea was fundamentally flawed based on the investor’s personal experience as a past founder working on a variant of the same idea. The investor also explained what paths forward our founder could take with clear and actionable ideas before the rejection.

After the rejection the founder told us “the investor is biased because he failed so if we succeed it will hurt his ego” and proceeded to ignore all his advice. Well 6 months later when we tried to get users on the platform everything the investor had said turned out true and the startup limped along for another couple years on angel funds, thankfully without me.

I think there is a difference between ignoring someone’s advice because it would “hurt his ego,” and believing that a fail in the past doesn’t mean a fail in the future. (- false fail if you will)

I thought about saying that bit of it more explicitly. But chose not to.

That said, there is a fine line. You want someone who defends their opinion on how things should be done.. And also someone who takes feedback. Therefore it seems valuable in the interview process to try to give feedback, and observe how the person responds. With HOW they process feedback being more important than whether or not they changed their minds.

Processing feedback by telling the internets about it would seem to be...a negative signal.

Speaking of negative signals the startup website linked in the substack comes across as one.

A lot of medical buzz words in what is becoming a very crowded area for AI (this is the third opthalmology related AI startup I’ve heard about this month) without any real substance to their claims, details or publications. Opthalmology is the farthest thing from my specialty (radiology) so I can’t comment whether the problem being described is worthwhile but there is also little to no detail provided.

The only substance is the EMNLP paper which is vaguely described as award winning although unspecified and was an interesting read but in my opinion objectively isn’t sufficiently technically impressive to be the whole pitch and hyped on the startup homepage and doesn’t really lend much direct credibility for the problem tackled.

Some of the links are also broken on mobile Safari.

I fully appreciate that this may be a stealth startup but that website is being linked in the post so I interpret that as an advertisement and intended to be read.

Hope to be proven wrong when more comes out but I’d suggest refining that website a bit more.

I was a co-founder of a startup in 2014, and we applied to an incubator that had experience with hardware startups, and domain expertise.

Here's where it got interesting, my co-founder was friends with the founder of another much more established startup in a vaguely similar space. The leader of the incubator was under the impression we were focusing on a different idea (we considered as a secondary, later opportunity) and concerned about a conflict between the two startups. If we had listened to his suggestion, we probably could have come up with a successful product opportunity.

At the end of the day, It was my own stupid fault for not listening closer to what was said, and analyzing the option to pivot into a more successful path.

Could also be both

The observation that YC companies tend to share a common shape is a pretty easy one to make. Who gets accepted or not is clearly a matter of fit and equally clearly has strong random chance effects.

Analyzing why the fit wasn't there is interesting. Your framing as "should have been accepted" (???) seems like you're thinking about this in a very different way from how it works.

Yep, glad you got the point. YC isn't some test where "passing" is the goal. As trite as it sounds, you are evaluating them as an accelerator as much as they are evaluating you as a startup - if the fit isn't there, either the startup changes itself or you move on. No big deal either way.

This is exactly right, not sure why you are getting downvoted. YC wouldn't work as an accelerator if there wasn't some pattern to their successes.

Yea a more realistic title would be - "We got rejected from YC, what I thought we did wrong"

I don't think the article claims A). The claim is that YC prefers companies that match a certain pattern and if yours does not then chances are not great. It mentions that other accelerators could be a fit though. It does not claim to have figured out how to not get rejected.

What would be valuable though is if they posted the feedback and rejection reason that they got from YC.

The article makes some salient observations and very good points, but yeah, I'm inclined to think this is another case of the sour grapes.
