Regtech & compliance software

We build dependable software for the way regulated business actually works.

LambdaChange designs, builds, and ships compliance-literate software — and advises the teams who run it. Engineering that understands the rules it has to satisfy.

What we do

Two things, done by the same people: the build, and the judgement behind it.

Most teams have to choose between engineers who don't know the regulation and advisers who don't ship code. We don't make you choose.

01 Compliance & regtech software

Custom tools for risk, governance, monitoring, reporting, and audit — built to be evidenced, traceable, and defensible. From a first internal tool to a system you can put in front of a regulator.

02 Consulting & advisory

Framing the problem, choosing the architecture, and de-risking delivery — with a team fluent in both code and controls. Engaged as a build partner or as a second pair of eyes on what you already have.

Capabilities

The kinds of problems we take on.

  • Risk & controls Controls tooling Registers, assessments, and monitoring that map cleanly to your control framework.
  • Reporting Regulatory reporting & evidence Reports and evidence packs that are reproducible and stand up to scrutiny.
  • Workflow Case & workflow management Reviews, approvals, and escalations with a complete, queryable history.
  • Data Pipelines & document processing Ingesting, structuring, and searching the documents your obligations live in.
  • Applied AI Automation, used responsibly AI and agents inside real workflows — with a human in the loop where it matters.
  • Assurance Audit trails & traceability Decisions and changes logged by default, so the answer to "show me" is always there.

Approach

How we work — and why it holds up later.

In regulated work, the bill comes due long after delivery. We build for that day.

  • Evidenced by default

    Decisions and changes are logged, traceable, and defensible — assurance is designed in, not bolted on.

  • Secure & data-minimal

    Secrets stay out of the codebase, access is least-privilege, and we hold the least data that does the job.

  • Reproducible & portable

    It runs the same on a laptop, in CI, and in production. No one-off setups that only one person can rebuild.

  • Plain-English first

    We explain the design — and its trade-offs — before we build it, so you own the decision, not just the result.
