HabitLock — Stop users from reverting to old workflows on day 3.

The Problem SaaS founders are losing 70–90% of signups by day 7, not because the product is broken, but because users revert to old habits under cognitive load. Traditional onboarding tools optimize for feature discovery, not for the moment when a user is tempted to abandon the new workflow entirely. No tool exists that systematically reduces friction at the exact point of habit abandonment. What We're Building HabitLock monitors user engagement patterns and triggers context-aware, problem-focused nudges on days 3–5 (the critical abandonment window). Instead of pushing features, we ask micro-commitment questions that reference the original pain point and unblock specific friction. A dashboard shows day-3, day-7, and day-30 retention cohorts by trigger type, so you can see what actually works. Who It's For Founders and retention ops leaders at early-stage B2B SaaS companies (YC-backed, pre-seed to Series A, $10k–$500k ARR) building niche, behavior-change products. Secondary: product tea
