Critical Embedded Software
We help teams apply formal verification to critical software components in embedded and systems codebases.
This is relevant when software faults are expensive because they affect:
- safety
- certification
- integration across suppliers
- mission success
- long-lived infrastructure
Where we fit
We are a good fit for:
- aerospace and defence programs
- automotive and software-defined vehicle platforms
- rail and other safety-critical transport systems
- critical infrastructure software
- tool vendors and engineering suppliers serving these sectors
Typical targets include:
- control logic
- mode management
- interface contracts
- safety invariants
- selected real-time or stateful components
- high-risk libraries in Rust or OCaml
What we do
We use the Rocq proof system together with our own translation and proof tooling to produce machine-checked proofs on selected properties of your code.
Our work usually starts from existing source code rather than a greenfield specification effort. We focus on the parts of a system where proof can add value beyond testing and simulation.
We can help with:
- formal verification as a service
- proof-oriented review of critical components
- supplier code assurance
- training and enablement for engineering teams
- custom tooling to connect source languages to proof workflows
Languages and tooling
Today, our strongest public tooling is around:
- Rust
- OCaml
- Solidity and related blockchain languages
The blockchain references on this website reflect our current public case studies, but the underlying methods are more general:
- source-level translation into Rocq
- replayable machine-checked proofs
- proofs that can be re-run as the implementation evolves
That same approach is relevant to critical embedded and infrastructure software.
How we work
The most effective engagements are usually narrow and concrete.
A typical project looks like:
- identify one component where failures are costly
- define a small set of properties worth proving
- connect the code to a proof workflow
- deliver machine-checked proofs and the supporting engineering artifacts
- keep the work maintainable as the code changes
This works better than trying to "formally verify everything" at once.
Why buyers care
Formal verification is useful when teams need stronger evidence on software that is:
- hard to test exhaustively
- costly to rework late
- certification-sensitive
- delivered by a supplier
- central to system safety or mission behavior
In those cases, proof can reduce uncertainty on the specific components that drive the most risk.
