Introducing Roughdraft! A new open source project designed to make collaboration with agents better. The idea is to bring commenting and suggested changes to markdown (e.g. plan docs) in a nice interface. Free, local, etc. 👉 roughdraft.md 👈

In 2016, we hired a 16yo software engineer. 10 years later, he and his cofounders have built a $2.75B company. Congrats @tejasmanohar @joshwget @kashgupta_, extremely proud of you all!

As a college student, Peter Reinhardt (@reinpk) started a company that stumbled, pivoted, and nearly ran out of money before a small open-source library became Segment—the data layer behind thousands of software companies and was later acquired by Twilio. On the Social Radars with @jesslivingston and @cjoneslevy, he reflects on the panic attacks, pricing mistakes, and how he learned to sell by listening hard to customers. Lessons he now carries into Charm Industrial, where he’s working to remove CO2 from the atmosphere and store it permanently underground. 00:00 – From MIT to YC: The ClassMetric idea 07:02 – When your customers don’t actually care 12:38 – A year in the wilderness building analytics 18:27 – Panic attacks and the lowest point 27:18 – The Hacker News post that saved the company 35:06 – Learning to sell (and asking for 1000x more) 44:52 – Hitting product-market fit the hard way 54:10 – The moment revenue started shrinking 1:02:33 – Selling Segment & starting Charm

Today we're introducing @usefiretiger. You and your AI agents write code. Firetiger makes sure it works. Our team and I have plenty of incident war stories building @Cloudflare, @segment, @Twitch. In the agentic coding era, the volume of code changes + quality issues in prod is ever increasing, but observability vendors aren't incentivized to close the gap. They make money when you write more data to them, not when your software actually works. Firetiger is the agentic operations layer for the agentic coding era. We combine production observability data, codebase understanding, and knowledge of your business to find problems before your customers do and fix them before they notice. We've raised $7.6 million led by @sequoia with participation from angels who believe in better software, including @eastdakota, @calvinfo, @NicoRosberg, @dok2001, @jeffawilke, and @alanaagoyal. You can sign up for @usefiretiger today, self serve. We charge for agents that directly make your software better and more reliable, not for observability data ingested, with plans starting at $599/month. Observability is dead. Long live outcome engineering.

My lobbyists are very nervous about me posting this, but over-regulation is working against us all. The costs are astronomical to us all, but hidden. So, I'm taking a risk, and sharing my stories from Charm and Revoy: rein.pk/over-regulatio…

Today we are launching my favorite feature of ChatGPT so far, called Pulse. It is initially available to Pro subscribers. Pulse works for you overnight, and keeps thinking about your interests, your connected data, your recent chats, and more. Every morning, you get a custom-generated set of stuff you might be interested in. It performs super well if you tell ChatGPT more about what's important to you. In regular chat, you could mention “I’d like to go visit Bora Bora someday” or “My kid is 6 months old and I’m interested in developmental milestones” and in the future you might get useful updates. Think of treating ChatGPT like a super-competent personal assistant: sometimes you ask for things you need in the moment, but if you share general preferences, it will do a good job for you proactively. This also points to what I believe is the future of ChatGPT: a shift from being all reactive to being significantly proactive, and extremely personalized. This is an early look, and right now only available to Pro subscribers. We will work hard to improve the quality over time and to find a way to bring it to Plus subscribers too. Huge congrats to @ChristinaHartW, @_samirism, and the team for building this.

As they say, some personal news– I just left @OpenAI after launching Codex. Extremely grateful to everyone there who I got the chance to work with and learn from. Still figuring out what's next, but there's a lot left to build out there.
