AI was as soon as once more the buzzword for this newest batch of YC Demo Day firms. Practically 190 firms participated in Y Combinator’s Winter ‘26 cohort and introduced their startups in a Demo Day on Tuesday.
These firms are engaged on merchandise throughout industries corresponding to regulation, transportation, and healthcare.
I didn’t, admittedly, hear to each single product pitch given the sheer measurement of the cohort and this yr’s Demo Day format out there to media: YC posted the pitch movies, one after the other, round 20 minutes after their shows (moderately than a livestream, or an in-person session invite).
As an alternative, I examine all 190 of the startups presenting and spent the day watching pitches from these we discovered intriguing, then narrowed it right down to the 16 that stood out as probably the most fascinating startups of this overflowing YC class.
ARC Prize Basis
What it does: Creates benchmarks to assist measure progress towards AGI.

This basis goals to encourage extra open-source AGI analysis by internet hosting competitions and awarding analysis grants. One motive for this AI revolution is to succeed in AGI (which Nvidia CEO Jensen Huang says has already arrived), and it is going to be a matter of historic file for monitoring how shut or we’re from AI machines that have a basic intelligence.
