The manager in the room for AI
Before any AI decision runs in your stack, Gatekeeper checks it against your policy and either lets it through, holds it for review, or blocks it. Every decision leaves a sealed, independently verifiable record

About Us
Oak and Sparrow builds Gatekeeper, the deterministic governance layer for AI. It checks every decision against your policy before it runs, not after, and records each one so you can prove what your AI did when a regulator or auditor asks.
We believe in a tailored approach, crafting innovative technology tools that are designed to fit each client’s unique needs. Our dedication to excellence and forward-thinking strategies set us apart, enabling our clients to stay ahead in an ever-changing digital world.
How we work
Three layers of governance for AI: checked before it runs, sealed into a verifiable record, and held to a policy pack built for your rules.
Pre-execution governance
Every AI decision passes through Gatekeeper before it runs. Clean ones proceed, risky ones pause, violations are blocked
Policy to your environment
Gatekeeper checks each decision against a policy pack built for your rules. It governs the decision, not the wording.
The sealed record
Every decision leaves a tamper-evident record, hash chained and independently verifiable. Not blockchain. Just proof.
Our Mission
We don't extract. We steward. Our mission is to build the ethical infrastructure for the automated age: to govern AI and protect our humanity. Every decision checked before it runs, every one recorded, so AI can serve people without escaping accountability.
