Nom. Healthy food, fast.

Just shipped the MVP of Nom πŸ₯‘ - a fast food scoring app.

No calorie counting, no guilt, just A-F grades based on real nutrition data. 17 chains. 700+ items.

"Starting today, free plan users can also try OpenAI o3-mini by selecting β€˜Reason’ in the message composer or by regenerating a response. This marks the first time a reasoning model has been made available to free users in ChatGPT."

Competition is good.

Not one VC would ever fund a startup to do the kind of hardcore optimization work that DeepSeek did.

Every VC firm should be asking themselves why.

Has anyone actually met their cofounder on YC Cofounder Matching?

I keep getting notifications about people from my school who just joined and I’m wondering how does it have anything to do with fit.
