Overview
A streaming AI pipeline and persistent memory system that gives startup founders a context-aware AI co-founder — remembering decisions, pivots, and milestones to deliver specific recommendations instead of generic answers.
Technical Details
Built a streaming AI pipeline using ReadableStream.tee() to fork the model response — one branch streams tokens to the user instantly while the other persists the conversation and auto-extracts context records in parallel, so memory saving never blocks the reply.
Designed a Founder Memory system that captures decisions, pivots, and milestones from user actions and injects the 10 most relevant records into every AI system prompt — replacing generic responses with context-specific recommendations.
Shipped Stripe subscription billing across 4 tiers with HMAC-verified webhooks and server-side feature gating; backend on InsForge (YC P26, Postgres BaaS) with row-level security and an isolated admin service client for privileged routes.
