nGrow automates push notification and email campaigns for mobile apps and web funnels with AI at multiple stages: generative content creation writes human-like subject lines and notification copy (the company’s own example: “4 subject lines for a 10% Black Friday discount” generated automatically), delivery optimization learns individual in-app user behavior to pick the best send time per user per journey step, predictive analytics flags churn risk through ML-based segmentation, and real-time AI-powered A/B testing optimizes campaigns as they run.
Per-user, per-step send-time optimization based on actual behavior – rather than one fixed send time for an entire campaign – is what actually drives the retention improvements the company reports, since different users genuinely engage with an app at different times, and a notification sent when a specific user isn’t likely to be active gets ignored regardless of how good the copy is. No-SDK, no-code setup with a 3-step integration also removes what’s typically a real engineering barrier for marketing teams wanting to run their own campaigns without waiting on a developer.
nGrow is Y Combinator W’22 backed, integrates with Firebase, Amplitude, and AppsFlyer, and reports case studies showing retention improvements of +12% to +33% for customers including Brickit and Fly XO. Pricing isn’t disclosed on the homepage.
