Parentlyze
A parenting product that turns family conversations into structured insights and tailored reports — spanning iOS/Android apps, web/Admin/backend, an in-house STT/AI engine, and internal operations systems. Co-founded 2025-06, CTO.
Overview
In June 2025 I co-founded Potentivo Lab and, as CTO, began building and operating Parentlyze's full product stack. Parentlyze records a parent-child conversation, diarizes and transcribes it, then turns it into tailored parenting reports and coaching missions. The Flutter iOS/Android apps, Next.js web layer (WebView content, report backend, operations Admin, and landing), in-house GPU STT/AI engine, and internal operations systems share one Supabase backend.
