Build Data + AI systems with evidence built in.
Coding agents can produce changes faster than teams can establish whether those changes are valid. Mitari is building a local, agent-compatible development layer that makes intent explicit, connects evidence from the tools you already use, and prepares every change for independent verification.
Built for data pipelines, analytics, machine learning, and AI systems.
A build-with-evidence layer, verified by Fathom
The forthcoming build-with-evidence layer prepares every change with intent, context, and evidence. Fathom — available now — independently verifies that work before it ships.
People and agents work with explicit intent, durable context, evaluations, and supporting evidence.
Passes the change and evidence forwardIndependently verifies the change, surrounding logic, and available evidence before it ships.
Verifies Data + AI code independentlyFaster code is not the same as verified work.
A coding agent can generate a pipeline, model, evaluation, or analytical query in minutes. But it may not know the intended data grain, the acceptable source window, the business definition of a metric, the assumptions behind an experiment, or the evidence required before a change should ship.
That context is often scattered across conversations, notebooks, tests, dashboards, monitoring systems, and people’s memories. By the time code reaches review, the reviewer sees the implementation—but not always the original intent or the evidence needed to judge it.
A development layer for verifiable systems
Make intent explicit
Describe what the system should do, what assumptions it relies on, and which constraints must remain true.
Give agents durable context
Help coding agents work from the same definitions, dependencies, and expectations as the people reviewing their output.
Use the tools you already trust
Connect tests, evaluations, metrics, lineage, monitoring signals, and custom checks rather than replacing your existing stack.
Preserve evidence as work changes
Keep the relevant results and decisions attached to the system from local development through review and operation.
Verify independently
Send the change and its supporting evidence to Fathom for an independent judgment before it ships.
Bring your own tools, checks, and evaluations.
Your existing systems already produce valuable signals. The forthcoming Mitari product is being designed to connect those signals—tests, evaluation harnesses, data-quality checks, lineage, metrics, monitoring, and internal controls—into a consistent body of evidence.
Teams should not have to replace their development environment, agent, data platform, or evaluation stack to make their systems more verifiable.
Evidence that travels with the system
Around your existing toolchain
Designed to work around your existing toolchain—not become another generic agent runtime.
Creation and verification should be connected—but independent.
The forthcoming product will help people and agents create and improve systems with structured intent and evidence. Fathom will independently verify their work.
