The breakthroughs I most want to see from AI are in medicine, not maths. @Petrichorbios are building wet labs for agents to make that possible.

Congrats on the launch @Wilhelmmlem, Jesper and Elias!

Today we're launching Petrichor (YC F26), a wet lab for frontier AI labs.

We run experiments in parallel and return the data from every step.

Bayworks automates the paperwork car mechanics hate, and that's just the start. They're already grown from 0 to 80 dealerships in just 4 months.

Congrats on the launch @bansal_kaustubh and @shubhamgl2003!

Self-driving companies record every mile a car drives. Nobody records how it gets fixed.

Bayworks (YC F26) does that, building the intelligence that keeps America’s vehicles running.

In 110 days, Bayworks has gone from 0 to 80+ dealerships covering 4,000 repairs a day, including a top-50 US dealer group ($3B+ annual revenue).

We capture voice and video data as technicians repair cars and verify the work, turning this ground truth into a system that runs the dealership’s operations and standardizes every repair.

Did you know Apple has to junk or rework 40% of iPhone Duos when they come off the assembly line?!

Introducing Hundred (YC F26), automated visual inspection for precision hardware parts.

Today, defects smaller than a grain of sand can cause functional issues in devices across consumer electronics, medtech, and aerospace, but manufacturers still rely on manual human inspection.

We're changing that.

DM us or learn more at hundred.systems.

I worked with this company last batch. Seeing growth like this from them feels crazy and inevitable at the same time

One month's progress for a successful startup. The previous month's towering revenue number now looks small, and the early part of the graph is starting to read as flat. This is what exponential growth feels like.
