Raintree Technology is Zachary Roth's independent software company and research practice. It builds BetterOff, publishes open-source developer tools, and researches reliable AI systems.
Built for humans. Ready for agents.
- BetterOff — Brings spending, investments, assets, debts, and net worth into one current household record, with inspectable answers grounded in customers' financial data.
- DocPull — Turns changing websites into cited, reproducible context that agents can verify before they act.
- PolicyStrata — Catches policy drift before release by turning cross-layer failures into deterministic, reproducible tests.
- HIG Doctor — Checks Apple-platform code against the HIG and cross-platform code against aligned accessibility and interface-quality rules.
- Trellis — Catches risky shortcuts, security footguns, and structural debt with shared Biome checks and deterministic JSON fix lists.
- Raintree Standards — Defines stable, testable requirements, evidence, task profiles, and exceptions for Raintree product and agent work.
PolicyStrata was accepted for an IEEE ISSRE 2026 Industry Track talk and demonstration. It tests policy drift in LLM data agents and states its evidence and limitations.
We build with source-linked context, scoped permissions, deterministic tests, human approval, and reproducible evidence.
