RetainPixel
Conversion infrastructure for apps that can't afford to guess.
RetainPixel captures product behavior, maps it into an activation ontology, and orchestrates interventions that taper away — until unsubsidized retention is your truth metric.
The platform that turns retention, activation, growth, habits, and conversion into measurable outcomes.
Interactive dashboard preview showing the RetainPixel activation pipeline with code editor, live event stream, and retention metrics.
See your activation pipeline
Every metric, experiment, and intervention — in one view.
RetainPixel offers six core features: RetainGraph activation ontology, Scaffold Decay Controller, Ghost Holdout Engine, Decision Engine, Internalization Metrics Suite, and Autopilot Mode.
Everything you need to prove retention
Built for founders who ship fast and measure what matters.
Map Your Habit Loop
RetainGraph Activation Ontology
12-state activation journey maps raw events to the behavioral milestones that matter. See exactly where users drop off.
Prove Retention Without Rewards
Scaffold Decay Controller
Taper interventions on a minimum-effective-dose schedule. Measure what sticks after subsidies stop.
Run Holdout Experiments
Ghost Holdout Engine
Randomized holdouts, silence windows, and weighted variant allocation. Know your lift is real, not noise.
Score Every Intervention
Decision Engine
Ranked candidate actions with explainable score components. Paywall timing and investment prompts are scored decisions, not static placements.
Measure Real Internalization
Internalization Metrics Suite
Five signals — IS, RDI, Voluntary Action Rate, Habit Velocity, Monetization Readiness — tell you when the habit is self-sustaining.
Launch Without Analytics Expertise
Autopilot Mode
Auto-detected milestones, suggested taper schedules, recommended reward budgets. One click to start your first activation challenge.
Ship in minutes, not months
Four steps from pixel to proven retention.
Install the Pixel
Drop a <5KB script tag or npm install. Zero dependencies. Events flow in under 10 seconds.
Map Your Events
RetainGraph maps raw events to the 12-state activation ontology. Autopilot suggests your milestones.
Run a Challenge
Launch a time-boxed activation challenge with tapering rewards. Ghost holdouts prove causation.
Measure Retention
Unsubsidized D30 retention is your truth metric. See the exact moment habits become self-sustaining.
Frequently Asked Questions
Everything you need to know about RetainPixel.
What is RetainPixel?
RetainPixel is conversion infrastructure that helps software apps prove unsubsidized retention. It captures product behavior, maps it to a 12-state activation ontology, runs tapering challenges with holdout experiments, and measures whether habits stick without incentives.
How does RetainPixel measure retention?
RetainPixel uses unsubsidized D30 retention as its truth metric. The Scaffold Decay Controller tapers interventions over time, and the Ghost Holdout Engine runs randomized experiments to measure causal lift — separating real habit formation from incentive-driven engagement.
What is the activation ontology?
The RetainGraph activation ontology is a 12-state model that maps raw product events to behavioral milestones. States range from first session to habitual usage, giving you a structured view of where users are in their activation journey and where they drop off.
How does scaffold decay work?
The Scaffold Decay Controller reduces interventions on a minimum-effective-dose schedule. It starts with full support, then tapers gradually. The retention that persists after all scaffolding is removed is your true, unsubsidized retention.
How long does it take to integrate RetainPixel?
Minutes. Install the <5KB SDK via script tag or npm, initialize with your project key, and start tracking events. Autopilot Mode auto-detects milestones and suggests taper schedules, so you can launch your first activation challenge immediately.
What makes RetainPixel different from analytics tools like Mixpanel or Amplitude?
Analytics tools measure what happened. RetainPixel proves what works. It orchestrates interventions, tapers them scientifically, runs holdout experiments, and measures whether retention persists without subsidies — infrastructure for proving habits, not dashboards for counting events.
What is a Ghost Holdout experiment?
A Ghost Holdout is RetainPixel's built-in A/B testing framework for retention. It randomly assigns users to treatment and holdout groups, pauses interventions for holdouts during silence windows, and measures the retention difference to prove causation, not just correlation.
What tech stack does RetainPixel use?
RetainPixel runs on Supabase for the database layer and Cloudflare Workers for edge compute. The SDK is a zero-dependency <5KB package with sub-10-second event latency. The dashboard is built with Next.js and deployed on Vercel.
