OpenGrowth Privacy-Preserving Federated Growth (MVP)

Overview

• A privacy-preserving federated platform enabling startups to run, share, and benchmark growth experiments (pricing, onboarding, activation, funnel optimization) without exposing raw user data.
• Local metrics are retained by each startup; secure aggregation yields aggregated results with confidence intervals.
• Data contracts, a schema registry, and a lightweight Graph-of-Contracts enable governance and cross-startup benchmarking.

Core MVP Components (visible in this repo)

• opengrowth_privacy_preserving_federated_
  • SchemaRegistry / ExperimentTemplate (minimal MVP) with tests validating basic behavior.
• opengrowth_privacy_preserving_federated_/contracts.py
  • LocalExperiment, SharedSignals, PlanDelta: lightweight DSL primitives for local experiments and cross-start signals.
  • GraphOfContracts: tiny in-process registry for versioned contracts.
• opengrowth_privacy_preserving_federated_/init.py
  • Exposes core MVP primitives and the new contract primitives for iterative federation development.

How to run tests and build locally

• Install in editable mode and run tests:
  • bash test.sh
• This ensures packaging works and the pytest suite passes.

Extending OpenGrowth (Recommended next steps)

• Implement a REST/MQTT adapter layer to connect to common analytics stacks (GA4, Segment, Amplitude) and CRM pipelines.
• Expand the governance layer with versioned templates, access controls, and audit logs.
• Implement a real secure aggregation backend (e.g., ADMM, DP knobs) and a cloud-anchored ledger for reproducibility.
• Build a small developer-focused DSL sketch and toy adapters to bootstrap cross-startup federation (CatOpt-like bridge).

Notes

• This repository is designed as a stepping-stone toward a production-grade platform. The MVP is intentionally small but designed for extension with minimal surface area impact.
• The test suite validates the core MVP contracts and aggregation primitives; ongoing work should extend tests for new features.

For contributors

• Keep changes small and well-scoped; add tests for any public API you introduce.
• Update AGENTS.md if architecture or contribution rules evolve.
