Every company starts somewhere, and in the case of Cheers, that was half of a rented garage in Orem, Utah. I was just finishing up my CS degree @ BYU when I had the idea for what became Cheers. I stopped going to classes (still somehow graduated), and went all in on an idea that…
Congratulations @kul on launching Phosphor Capital! I've know Kulveer my whole life and it's not surprised me that he's been consistently rated as one of the absolute best investors by YC founders every batch. Former founders make the best investors ❤️ techcrunch.com/2025/07/03/y-c……
Kulveer is an amazing human being and a great investor in YC startups, and I am so excited to see what he is doing with Phosphor Capital!

Not many people know this, but OpenAI was actually started at YC in 2015, and was initially known as "YC Research". We were concerned that all of the AI technology would be locked up inside of one company (Google), and so created a "moonshot" effort to make the technology…
Pleasure to come by the YC AI Startup School today! I'm told the recordings will be up "in the coming weeks", I'll link to it then and include the slides. Thank you YC for organizing and bringing together an awesome group of builders! events.ycombinator.com/ai-sus Fun fact is that…
Congratulations to Extend from the YC W23 batch. Incredible customer logos, incredible growth rate. Way to go, Kushal!
PDFs suck. We just raised $17,000,000 in funding to fix this problem once and for all. Extend is building the modern document processing cloud. See how Brex, Square, Checkr, and Fortune 500s use it to process millions of documents:
