As I wrap up my summer internship at 25madison, I’ve been reflecting on all the rapid iteration
and thought-provoking moments that come with working at a venture studio. Every day here has
been a crash course in curiosity, creativity, and collaboration. I have personally been validating
exciting ideas in healthtech and AI alongside the 25m Health team.
We’re a lean team, but it feels like things are moving at warp speed, so I started asking around
about what tools we’re all using to get things done faster (and smarter).
The answers were just too good not to share. From building websites in a day, to spinning up
dashboards and writing copy, these are the tools powering our team’s day-to-day. Special
shoutout to Claude Code, the clear office favorite 🤖
