Jobs called computers "bicycles for the mind" -- tools we could shape to our will. But they never were. Until now. Every morning an agent preps me for my day -- calendar, news, last 24hrs of Slack -- in a personal podcast. I made it by asking. Same for hundreds of other things.

At Stripe we care about being meticulous in our craft. Sometimes that means putting effort into getting the small things right. Little details compound into end to end experiences that are surprisingly great. We shipped 100s of tiny tweaks last year. Some of my favorites 🧵

🚀 Excited to announce my new company: /dev/agents. I’m building the next-gen operating system for AI agents, joining my former colleagues @hbarra, @alcor, and @ficus as co-founders. We're excited to partner with @ninaachadjian (Index Ventures) and @jillchase124 (CapitalG).

Last week I spent a couple of days writing code @stripe. We think about and invest a lot in our internal developer experience. Having spent >10 yrs at Google I like to think I have a high bar. But last week's experience was substantially better than anything I've seen at scale.

We just shared our annual letter, including how we engineer for reliability as we deploy new code in our core API services ~400 times daily at trillion dollar scale. Once a change is code-complete, it's evaluated by ~1.4 million tests.

In Lagos where I met @shollsman, @0x, and the team from @paystack. We spoke about the opportunity to increase the GDP of the internet in Nigeria—and across Africa—and ways that engineering team at Stripe can help support this mission.

I built a fun toy / proof of concept this afternoon. It's a probabilistic spreadsheet. Ever since a university lecturer taught us to build spreadsheet models and play around with inputs and understand how sensitive the output was to that variable, I wished this was built in.

Project day, I guess. Helped my daughter make an @arduino controlled set of traffic lights. Her little fingers are very dexterous - she's much better than me at plugging jumper wires into the breadboard. 👨‍👧🚦

Yesterday my daughter (nearly 4) went on the #WomensMarchSF. Tonight: "It's time to get out of the bath!" "No Daddy, it's not your choice, no man can tell me what to do! On the march they told me 'your body, your choice'." #daddysbeenowned

Businesses on Stripe have asked how we handle Black Friday–Cyber Monday. So, we built a live dashboard to show exactly how. For the very first time, you can see request load, API uptime, and live transaction data across the entire Stripe network: bfcm.stripe.dev.
Businesses process more than $18.6 billion on Stripe over Black Friday and Cyber Monday
