jean weatherwax
a generalist, by happy accident.
happiest when I can get outside regularly.
Broad training. Deep curiosity. Hardware & circuits first. Software, always.
I care about the thing on the other side of the screen, the person who has to use what I build, and whether it actually makes their life a little better. I like hard problems in many disciplines. I go deep on new things, often. I change my mind when the evidence asks me to. Most recently, the founder chapter. Co-founded an AI company, wound it down, returned capital, kept the lessons. Before that, led engineering at First Round Capital for three and a half years. Before that, a scattered list of places that each taught me something lasting.

- AI Furby 2026
rewired a 1998 furby with whisper, claude, and elevenlabs. it judges you.
raspberry pi zero + arduino nano, driving the original motor, speaker, and light sensor. it wakes with the lights and falls asleep in the dark. the world needed an ai furby with strong opinions about the 90s. · watch ↗
- Lockin 2026
a macos focus monitor that catches you drifting before you do.
watches real-time app and browser activity, classifies it against your stated session goal with claude, and nudges gently. built for someone i love. swift + local sqlite. · github ↗
- Parsley 2026
personal podcast parser. transcribes and analyzes podcasts on your mac.
a quiet little tool i built for myself. considering open-sourcing it. · site ↗
- Memristor CIM Simulator 2026
where energy goes in a compute-in-memory crossbar. every parameter traces to a paper.
calibrated simulator of a memristor crossbar. for high-conductance hfo2 cells, the crossbar dominates per-inference energy, not the adc. a revisit of old hp labs territory with the tools of now. · github ↗
- BaseBeta 2019 →
a resource for base jumpers. built with a friend who is no longer with us.
currently off the app store. we are working on bringing it back as a promise kept.
- A stealth AI company 2025 — 2026
co-founded. wound down. returned capital. kept the lessons.
started with next-gen cpq. ruled out a lot of ideas before that. most recently, context graphs that enforced business rules on agent behavior at runtime. the right problem, roughly. a little early, or a little wrong. honesty is a feature. thank you to everyone who backed it.
