Gemini 4 Changed How Google Builds Products | Jaclyn Konzelmann
Google Labs product director Jaclyn Konzelmann tells Peter Yang how Gemini 4 shifted her team from asking whether something can be built to whether it should exist, plus how she uses AI with her kids.
The gist
-
Konzelmann says she now starts projects with a short strategy doc, a presentation and a prototype instead of a 40-page PRD.
-
Her doc rule: if reading it takes longer than producing it, it's not allowed, and her strategy docs average about one and a half pages.
-
Labs culture runs on "build to learn" and "keep the lessons, not the prototype," so an ended experiment is never treated as a failure.
-
She had an agent fix a GPS glitch in Strava, arguing products should remove tedious tasks while keeping the parts people enjoy.
-
With her kids, she makes a scary stories podcast using ElevenLabs and a banana slug song with Flow Music, while still letting them get bored.
