I've been telling my story of how we turned Bump into Google Photos to new YC founders at the start of each batch. I hope sharing it more broadly inspires even a few founders to go build the future for all the rest of us. Full video in the replies.
Fun fact: @typingwala and I started working on @simstudioai 3 weeks before applying to YC. We applied an hour before the deadline on a whim. We couldn’t believe it when we got in. These stories are more common than you think. Go apply! @ycombinator
Applications for the YC Fall 2025 batch are now open! Apply by August 4: ycombinator.com/apply
Biggest interaction gap for AI assistants: they still can’t see my screen, let me point at things with my finger, or let me sketch on top of it like a whiteboard.
It will soon be a violation of the Hippocratic oath to not use AI in healthcare.
9 years to get to $10M ARR; 9 months to $100M+. Replit is a story of a founder with a vision finally unlocked by AI.
Amjad Massad (@amasad) started Replit to make programming accessible to anyone, anywhere. What began as a tool for learning to code has grown into a platform pushing the limits of AI-assisted software creation and recently surpassed $100M in ARR. On The Breakdown with @t_blom…
One thing I'm certain of is that Legora is going to be one of the generational applied AI companies. Today is the time to join the team.
Build a company good enough to get bought twice.
Always enjoy talking to @dflieb on and off camera about everything: search, AI, product. In this video, we discuss why the next big bet is to nail agents and the browser. Thanks to @garrytan for inviting me.

I wrote about how @ZeusLiving (YC S11) survived the pandemic in a thread that went viral with over 2M views. Here's the update and what I'm up to next. 2021: Zeus survived COVID 2022: Chewed glass & made the portfolio profitable 2023: Sold Zeus to @theblueground (40,000+ homes)…
2020 was a challenging year. The pandemic crushed my startup, @ZeusLiving. We were in a mad fight for survival. I learned a lot about resilience, teamwork & belief, whilst making some mistakes along the way. I'll share some of that experience here. /Thread

This is my new favorite app. AI auto fills your 311 report from a photo and your location.
I've been working with 311 on perfecting the AI classification of issues in Solve SF. The AI knows how to fill out all the report details, so you don't need to. This is great for those of us reporting issues - we just need to submit a photo, and the AI handles the rest. And…
Thank you, Comet!
I desperately want to connect my Gmail, Calendar, and Google Photos to ChatGPT so it can know my life and help me more. Today’s example: “when was my last haircut?” Kind of absurd that Gemini doesn’t have this already. What a self own.
This seems like the way Google (or Apple) could actually beat ChatGPT.
