The business development team your firm never had.
Lexi spots the leads worth calling in business, patent and trade mark data, writes the first note and every follow-up for you to approve, keeps your CRM filled from email and calendar and tells each colleague what to do next. You talk to her in Teams, WhatsApp or email.
Lexi works in Teams, WhatsApp and email. There is nothing new to log into.






The work goes to the firm that moves first.
Every week a client goes quiet, a meeting ends without a follow-up and a company in your market files something new. Most of it is already in your inbox or on a public register. Nobody at the firm has the hours to act on it, so the next mandate goes to whoever does.
The client who went quiet
Nobody had written to them since the spring. By the time anyone noticed, another firm had the work.
The mandate nobody was credited for
Two partners remember bringing it in differently, and the compensation conversation happens in a room, from memory.
The hour before every meeting
Reading back through eighteen months of email so you can walk in knowing what you already agreed.
Lexi notices the quiet client, keeps the record of who brought each client in and has the brief written before you walk into the meeting. Your firm moves first.
Characters are AI generatedWhen a partner leaves, the relationships stay with the firm.
Lexi does the business development work. You make the call.
There is no dashboard to check and no form to fill in. You ask for what you need the way you would ask a good associate, in Teams, WhatsApp or email, and the briefing, the draft or the answer comes back.

It happens while you are in court.
Twelve follow-ups from last week’s conference, written. Your two o’clock briefing, prepared. A business card filed against the right company. It is all waiting when you come out of court, and nothing goes out until you approve it, one message at a time or as a sequence you set up.

Ask for it two minutes before a meeting.
“Prep me for my 2pm with Halvorsen Medtech.” Who is in the room, what you last agreed, what they have filed since, answered in Teams or WhatsApp while you walk to it.

The brief is ready before you are.
Thirty minutes before a client meeting, the brief is written: who is in the room, what happened since you last met, what the client has filed and what to raise. Built from the email, the calendar and the registers, not from memory.
Everything business development needs, and nothing to fill in.
It runs every day on your mailbox, your calendar and public business data. Ask for any of it in Teams, WhatsApp or email, the way you would ask a colleague.






Every client, prospect and referrer, with who introduced them, who has met them since, and which partner they actually pick up the phone to. It fills itself from Outlook or Gmail and your calendar, so nobody types a client into a system. It can be your firm’s CRM. If you already use HubSpot, keep it: contacts, companies and deals sync both ways. Moving from another CRM? We help you migrate.
Access to 270M+ business contacts across 480+ industries, from general counsel and in-house lawyers to heads of IP, filtered by industry and jurisdiction, ranked by what you already have with them, with a first message written.
Plain-English rules that turn an event into a draft. When a client files a new patent or trade mark, the client team hears about it and the update email is already written for a partner to read. When a client has gone quiet for sixty days, the note to reopen it is waiting. Anyone on your team can set up a rule.
Development, acquisition and retention in one place. Who introduced a client and who won them, answered from the introductions, emails and meetings that actually happened, not from memory in a room at the end of the year. Lexi shows the evidence behind each credit, and the account owner can change it.
Follow-ups written in your voice and sent from your own Outlook on a schedule a partner sets and approves: the thank-you after a meeting, the cost estimate three days later, the check-in after ten. The moment the client replies, the sequence stops and the reply lands on the record.
Photograph the cards at the stand. By the time you sit down, the contacts are in, each on the right company, and the follow-ups are drafted.

Events & conferences
Photograph the cards at the stand. By the time you sit down, the contacts are in, each on the right company, and the follow-ups are drafted.
The registers, read against your own clients.
New patent and trade mark filings from the companies you watch, next to the people you already know there. The EPO and EUIPO are live, the national EU registers are in beta, the USPTO is next and WIPO is planned.
Firms that stopped doing this by hand.

“What used to take our BD team an entire Monday morning now happens before I’ve finished my coffee. Lexi drafts the outreach, preps the briefings, tracks the follow-ups — and honestly, for the first time in twenty years, business development actually feels enjoyable.”

Notes on AI business development for law firms.

Marketing and BD Are Different Jobs (and Most Law Firms Conflate Them)
Marketing builds the brand. BD builds the pipeline. Conflating them produces a function that does neither well, and partners who trust neither.

The Four Functions of Legal Business Development
Every law-firm BD function does four jobs: origination, retention, expansion, and intelligence. Most IP firms over-invest in the first and neglect the other three.

A design partnership with Gevers
Gevers, a pioneer in IP and one of the largest IP law firms in Europe, has joined LeadLex as a design partner. A 24-month partnership to build the growth infrastructure for the modern IP firm.
8 min readWhere did last quarter’s work actually come from?
Every partner has an answer. None of them are written down, and they do not agree. The firm then makes its compensation, hiring and marketing decisions on whichever version was said most confidently in the room.
Origination, from the record
Who made the introduction, who did the work of winning them, and what each partner’s effort actually produced, answered from the emails and meetings that took place, not from recollection in December.
What a departure costs you
When a partner leaves, their clients, their history and their commitments stay with the firm. That is the difference between a book the firm owns and one it was only borrowing.
Built for law firms. IP firms get the registers too.
Built for confidentiality from day one.
Nothing reaches a client without a partner’s approval, given one message at a time or once for a sequence. Sending and other actions follow the mode your firm chooses: individual confirmation, or an agreed automated workflow with defined recipients, limits and stopping rules. Your firm’s database, files and backups are held in Frankfurt, Germany, and you can see the whole product on a demo workspace before anything of yours is connected.
Data protection
LeadLex acts as processor under Article 28 GDPR. Our DPA covers instructions, security measures, sub-processing, assistance, audits and the return or deletion of data.
ISO 27001
ISO/IEC 27001 certification is in preparation.
SOC 2
A SOC 2 examination is in preparation.
AI data handling
We do not use customer data to train our own models. The AI providers enabled for your firm are listed in your provider schedule, together with their retention and transfer terms.
Workspace separation
Each customer workspace is isolated through workspace authorisation and database policies, and each workspace has its own AI environment with encrypted storage. Within a firm, access follows administrator, member and viewer roles.
See it work on your own clients.
Forty-five minutes. Start on a demo workspace, or, once the security review is done, on one of your own mailboxes and your client list. You watch it prepare the briefings, draft the follow-ups and find the people and companies worth calling next.
Your confidential data is connected only after the agreed security review.
