What we do · Build

Full build

A validated prototype becomes a production platform your firm owns - enterprise architecture, our lawyer-trained AI agents, and fee earners in the loop so it fits their work from day one.

The premise

Software you rent is a cost. Software you own is an asset.

Every platform your firm licenses adds capability everyone else can buy too - the same tools at the same price. A platform you own compounds differently: it encodes your expertise, fits your delivery, and its value accrues to you.

We take a validated prototype to production - enterprise architecture, our lawyer-trained AI agents, your fee earners in the loop - and hand you the IP at the end.

The build · Three to six months

From blueprint to production

Four phases, visible progress throughout - agile sprints and regular check-ins rather than a big reveal at the end.

Phase 01 · Blueprint

Architecture before ambition

The platform is designed before it is built: system architecture, security framework, data model and stack selection - engineered for the sensitivity of legal work and the scale the product needs to reach.

  • System architecture and API specification
  • Zero-trust security designed in from the start
  • Scalability planned, not patched in later
Phase 02 · Development

Build at agent speed

Core development runs on our proprietary library of lawyer-trained AI agents - extraction, chronology, checking and grading capabilities that already understand legal work, tuned to your playbook rather than trained from zero.

  • Proprietary agent library accelerates the core
  • Your workflows encoded, your playbook applied
  • Quality assurance running from the first sprint
Phase 03 · Co-creation

Fee earners in the loop

The platform is shaped with the people who will deliver through it. User acceptance testing runs continuously, and feedback becomes features in days - so the product fits the workflow before launch day, not after.

  • Continuous UAT with the delivery team
  • Feedback shipped inside a week
  • Workflow fit proven before go-live
Phase 04 · Deployment

Launched, adopted, supported

Production deployment with security hardening, monitoring and support SLAs from day one - and a training programme that makes the first week feel familiar. The platform goes live with its keys in your hand.

  • Production deployment and hardening
  • Training for day-one adoption
  • Tiered support and SLAs from launch
What you leave with

The keys, the manual, and the deed

  • The platform

    A production-ready platform on enterprise-grade architecture, deployed and monitored.

  • The IP

    You own everything we build. No licence fees, no lock-in, no rent on your own product.

  • Runbook & training

    Documentation, training and support structures that make the platform the firm's, not ours.

  • Ongoing support

    Tiered support with SLAs and strategic reviews - from launch through to long-term growth.

Why Purple

Legaltech we built runs in 150+ firms

This is not our first platform. Legaltech we have built runs in over 150 UK and US firms, on the same foundations we will use for yours - and the team that shapes the strategy is the team that ships the product. No handover, no delivery partner, no deck-and-disappear.

See the products in our work, or start smaller with a four-week prototype.

The first step

Build the platform your firm owns

Three to six months from validated prototype to production platform - secure, adopted, and yours. Bring the prototype, or start with one.
