AI makes development faster, but faster is seldom safer.
Propellerhead stands in that gap: A delivery team that combines the throughput of AI with the rules, standards, tools and accountability that enterprise systems demand.
Each initiative starts with a specification. We define what needs to be built before AI-generated code is written.
Where appropriate, we use rapid prototyping of a functional demo to enable fast decision-making.
AI allows fast iterations for experimentation and testing ideas.
Generated code runs inside carefully human-crafted runtimes – no generated code has direct interaction with infrastructure.
No agents run in production; only deterministic, testable code.
Generated code doesn’t reach production on autopilot. Every release passes through highly-experienced reviewers. Speed never comes at the cost of a checkpoint.
All services use standards-based telemetry for metrics monitoring and alerting.
While no agents run in production, our support team uses agent-assisted troubleshooting, feeding any needed repairs back through the governed loop.
Every decision and change is captured and stored alongside the code. The current state of the specification always matches the code.
