Lots of people asked how I used Fable to edit its own launch video so I made a video about that! TLDR it wrote a lot of code & tool calls to use transcription services, ffmpeg, do colorgrading, use the figma mcp, make remotion UI and render it. I didn't touch a video editor.

Most VCs shied away from Anthropic in 2023. Not Yasmin Razavi. The Spark Capital partner led a $450M round when Anthropic had no public product, no revenue and a massive capital need. Now the AI giant’s rise has landed her on the #ForbesMidas List for the first time. forbes.com/sites/iainmartin/… 📸: Guerin Blask For Forbes

Conductor has the distinct edge of being an IDE born for coding agents. An ADE if you will. Agents will take remote dev mainstream. At most large and sensitive organizations, “local” isn’t a thing. But this future wasn’t evenly distributed. Excited to power their Sandbox!

Conductor (@conductor_build) is a Mac app that lets you run multiple coding agents at the same time. Create an isolated copy of your codebase in one click, tell Claude or Codex to go work, and review and merge the results. The company just raised a $22 million Series A, and today is launching Conductor Cloud, which lets agents keep working even after you close your laptop. In this episode of Founder Firesides, co-founders @charlieholtz and @jacksondecampos sat down with YC's @aaron_epstein to talk about cycling through a dozen ideas before landing on the one that stuck, how building dev tools for themselves led to Conductor, and what they've learned from watching the best engineers in the world work with coding agents every day.

Proactive agent that thinks and acts like you. Multiplayer AI Brain for teams. Proper GUI for commanding 50 agents. Sauna.ai is all three. Sauna goes live today. First 2000 people, use access code LAUNCH for $80 of weekly(!) credits. Let’s explain. Multiplayer only works once the personal brain is powerful. So let's start here. Personal AI Brain 3,800 tools connected. State of the Art memory. Skills and schedules you teach once that get repeated forever on cheaper models. An AI first CRM. Lives on the cloud so you can initiate tasks from anywhere: iMessage, Slack, Email. Also no need for a Mac mini 😉 GUI AI agents have been stuck in their MS-DOS era. A chat box, a scroll buffer, no way to command 50 of them. We built the first GUI: Live sessions on one side, work waiting for your sign-off on the other, plus the things Sauna kicked off while you were asleep waiting for review. Game mode helps clear the queue with actual joy. Okay so far so good, but how to give benefit of what you built to more people or whole team? Multiplayer Once your Sauna actually knows you and you gave her access to your tools, you can use multiplayer. Two modes: - Brain access. My co-founder Robert plugged my brain as a tool into his Sauna last month. He can ask it about pricing while I'm in other meetings, gets a sourced answer back, never has to interrupt me. That’s read only. Yolo mode gives him access to all my tools too :O - Communal Saunas extend that to whole companies with proper permissioning. Folder owners decide what's true for the whole company and build skills. Most get their personal brain read access to communal files and memories. Works also for group planning my best friend's bachelor party. The Way I’ve been obsessed about AI Brain since 2016. Our human brains suck at some things like memory and are brilliant at others like creativity. We are also particularly bad at thinking we are all on the same page and then realising weeks later that we weren’t. Most leaders spend their days being the human diff tool, catching contradictions in hallway conversations and Slack threads. Repeating themselves 50 times. Now every company is spinning up hundreds or thousands of agents that drift faster than humans do, feeding each other their drift as context. Compounding rot. After 10 years and one failed company in this space we are launching the solution. The Launch We thought about a celebrity launch. Margot Robbie in a bathtub explaining agents. But then we realised the same money gives the first 2,000 people free daily credits, every day, until we burn through that $1,000,000. Sauna runs Claude, GPT-5, Gemini, GLM-5.1, DeepSeek, Kimi so you can budget yourself. The labs are racing to lock you so they can milk you in a year. We picked your side. Onboarding It’s live at app.sauna.ai We’ve preheated saunas based on a niche. Use the access codes in the comments to get a better experience.

Big news for @conductor_build! We've raised a $22m Series A from Spark and Matrix. We raised this round from @ilyasu at Matrix, who also led our seed round and is joining our board, @nabeel at Spark, @ycombinator, and founders of Notion and Linear. We're grateful to be working with investors we trust and admire. Here’s how we got here and where we’re going:

Today we're announcing our Series C alongside some big updates that make @meetgranola better for your team and your tools. Excited to partner with Danny at Index and Mamoon at KP. Big things to come. Back to work!

this is pretty much the only way to build product in AI models move so fast, that you have to be willing to throw everything out every few months to take advantage of what's possible

“Hey Claude, watch Love Island for me” -said no one ever No one wants to automate leisure, which is what the vast majority of consumer behavior is. This is why IFTTT failed while Zapier (B2B productivity) succeeded.

If you like CCGs and board games - this kickstarter is a really clever and fun mashup that my friends made.
