Legal projects we have shipped

  • InMyNameKYC: client onboarding for law firms

    A white-label onboarding platform that UK law firms run under their own branding. A new client verifies their identity on their phone, passes anti-money-laundering checks, signs the engagement letter and sets up a Direct Debit, all from one link. We built it on the web and on mobile.

  • A UK legal-tech company: full-stack work on a live platform

    Ongoing development for a UK legal-tech company's software platform on C#, .NET, Angular and Microsoft Azure, including Office add-ins. The work covers new features, fixes and deployments. We use Claude Code in the daily workflow, and every change goes through the client team's own review before it is merged.

  • OuterDocs: document automation, built for a contractor

    This one is not a law firm, but it is the same document problem. A US contractor's proposals, requests for proposal and contracts now come from 69 master templates. Each is filled from the deal's own data, and Claude compares every finished page with the master before a person reads, edits and sends it.

Who does the work

4.9 out of 5 on Clutch

Full-time engineers and designers in our own office. No freelancers and no subcontractors. The senior engineer from your first call writes the code and stays on the project until handover. Our engineers build with Claude Code every day, and the products we deliver run on Claude, OpenAI's GPT models or Google's Gemini, chosen for the task.

Questions about legal software

Does the AI give legal advice?

No. It fills and checks documents from your templates and your data. A lawyer reads and approves everything that goes to a client.

Can it run under our firm's branding?

Yes. InMyNameKYC is white-label, so each firm's clients see that firm's name and branding.

Can you work on a platform we already have?

Yes. For a UK legal-tech company we work inside their existing codebase and their own review process.
