You don’t get Jobs’ “misfits” without betting on their tools. The weird libraries. The unloved runtimes. The stuff that feels a version too early. That’s where the edge is. Effect | TypeScript at Scale and Rocicorp aren’t just tech bets. They’re talent filters.

Pascal nailed it. We discussed this exact pattern months ago. Bounce • Storage for your stuff and Reflectly App are still thriving because day 1 we were in customers' hands, not our IDEs. Simple but most founders get it backwards.

AI won’t write your core architecture, but it will ship the delightful features your team never had time for., “nice-to-have” becomes default.

Bounce was built on Elixir ⚡️ At Precurion we also bet on off-beat stacks Today it’s EffectTS + Zero Sharper edge, built-in talent filter, tribe on fire. Nothing beats shipping shoulder to shoulder with builders like Afonso Matos 🇵🇹 🚀

the AI part of multi-agent systems is easy, the plumbing is hell Implemented Effect | TypeScript at Scale for agent workflows and i can actually see what’s breaking now. It just works. this is game changing

The founder journey: Being wrong confidently → Being wrong publicly → Being less wrong → Being occasionally right Once you embrace this you can the loop faster

Really starting to get the point of Effect | TypeScript at Scale AIPlan feature - navigating LLM providers’ rate and usage limits is a maze. AIPlan lets you account for the unpredictability up front

AI + email templates = perfect match. Finally someone else can deal with the Outlook-compatible table hell and remember which CSS actually works in Gmail 🙃

Sitting in a Harlem jazz club watching this unfold, I realized it’s the same process as building startups. You begin with a plan, then improvise based on feedback. The jazz musicians embrace that most of their ideas are stepping stones, not destinations

“Attention is All You Need” was about AI. Now it’s about us. With Cursor background agents, code writes itself. All I provide is attention. Since everyone has the same AI, the competitive edge left is who can stare longer. We automated everything except knowing when to stop
