Built by intellectual-property people. For IP firms.
LeadLex was founded by a team that came up in the IP world — patents, trademarks, designs, prosecution cycles, INTA season, renewal calendars.

The relationships were there. The tools to manage them weren’t.
We spent years watching IP firms lose work to firms with better BD infrastructure, not better lawyers.
We didn’t build a better CRM. We built the operating layer we wished we’d had — one that joins every system in an IP firm’s day into a single, current view of the practice. The four ambitions every well-run IP firm’s strategic plan carries — deeper client relationships, a professionalised BD function, sustainable organic growth, operational efficiency — become operable when the infrastructure exists to execute them.
Munich and Potsdam. The densest cluster of patent attorneys in Europe, and an R&D branch supported by the State of Brandenburg.
Munich — headquarters
Home of the European Patent Office and the densest cluster of patent attorneys in Europe.
Potsdam — R&D branch
Where the IP-native data layer is built, supported by the State of Brandenburg.
Our first cheques came from working IP partners. The people whose day jobs we set out to make better.
LeadLex receives R&D funding from Investitionsbank des Landes Brandenburg (ILB) for the IP-native data layer that powers Lexi.
The best IP firms should win on talent, not on admin.
Book a demoThree principles that shape everything we build.
We’re building the operating layer that lets partners focus on the work that matters. Lexi handles BD operations in the background — every outbound action queued for your approval — so the firm’s relationship infrastructure is finally as good as the lawyers running it.
- 01
Domain first
Built by people who spent years in legal BD. Every feature starts from a real workflow, not a product roadmap.
- 02
Trust & transparency
Your data, your control, always. No model training on client data. Full audit logging. DPA included on every plan.
- 03
Relentless simplicity
AI should remove complexity, not add it. If a partner can’t use it in 30 seconds, we haven’t finished building it.
Built with Claude.
Lexi’s intelligence is powered by Claude, Anthropic’s frontier AI model. We chose Claude for its reasoning depth, safety commitment, and enterprise-grade reliability — values that are non-negotiable in a legal context. Your conversations with Lexi are private, confidential, and never used for training.

We onboard one IP firm at a time — and hire the same way. A small team in Munich and Potsdam, working with patent and trademark partners across Europe to build the operating layer for IP BD.
