Many companies are #1 in a benchmark they crafted. We worked with @micro1 to create an independently audited benchmark to measure document extraction performance with long documents. The results of LongExtractBench show the nuances companies are likely to find in the real

Over the last decade, we’ve built robots that can run marathons, harvest food, and even dance. But robots still aren’t very good at the simple tasks we use our hands for, like unpacking groceries or tying a shoelace. Most rely on simple grippers that aren’t much better than a

In Sep 2024, I left a job I loved to start @proceptionAI with one obsession: to give robots hands that actually work. 20 months. 20 people in Mountain View. A lot of Coke Zero. Today we ship.

Supabase now has more than 7 million developers building on it. It all started with a tagline change. @kiwicopple changed @supabase's tagline to "Open-source Firebase alternative." Someone posted it to Hacker News the next day. It shot to the top. He hadn't shipped a single new

I met @jasonyuan in 2024 while he was building Dot at @newcomputer. I was struck by his thoughtfulness, authenticity, and deep passion for what he was building, and as I looked at what he’s created over time, it became clear that he’s a special person whose intuition allows him

Back in 2013, when I was starting Cover, I was introduced to @bryantchou. I was so impressed by his technical chops and raw intensity that I tried to hire him as our founding engineer. He politely declined to start his own new company instead, called Webflow. But we stayed in
