Firms deploying LeadLex




The work goes to the firm that moves first.
Clients file, change counsel and go quiet every week. Most of it is public or already sitting in your inbox. Nobody at the firm has the hours to act on it, so the next mandate goes to whoever does.
The filing you heard about too late
Your client filed in a new field last month. Another firm called them first.
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.
LeadLex does this work, so your firm moves first.
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 INTA, 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.
Ask for it two minutes before a meeting.
“Prep me for my 2pm with Hartley Vance.” Who is in the room, what you last agreed, what they have filed since, answered in Teams or WhatsApp while you walk to it.
It picks up how your firm works.
That Dr. Reinhardt answers on Teams and never on email. That a client gets a note after sixty quiet days. That Rhenwald needs a partner to sign off. It keeps what the firm tells it, and applies it next time without being reminded.
Everything business development needs, and nothing to fill in.
It runs off your mailbox, your calendar and the registers every day. 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, your calendar and Teams, so nobody types a client into a system. That is why the last one you bought went stale and this one does not.
Access to 270M+ business contacts across 480+ industries, from in-house counsel to GCs and IP managers, filtered to your technologies and jurisdictions, 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 at the EPO, 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.
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.
Outlook, Gmail, your calendar, Teams and HubSpot, connected with OAuth and revocable per channel. It reads what is already there; it does not ask your partners to work somewhere new.
Photograph the cards at the stand. By the time you sit down, the contacts are in, joined to their filings, and the follow-ups are drafted.
Network & CRM
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, your calendar and Teams, so nobody types a client into a system. That is why the last one you bought went stale and this one does not.
Prospector
Access to 270M+ business contacts across 480+ industries, from in-house counsel to GCs and IP managers, filtered to your technologies and jurisdictions, ranked by what you already have with them, with a first message written.
Automations
Plain-English rules that turn an event into a draft. When a client files at the EPO, 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.
Deals, origination & reporting
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.
Integrations
Outlook, Gmail, your calendar, Teams and HubSpot, connected with OAuth and revocable per channel. It reads what is already there; it does not ask your partners to work somewhere new.
Events & conferences
Photograph the cards at the stand. By the time you sit down, the contacts are in, joined to their filings, and the follow-ups are drafted.
From a trade mark filing to the next mandate.
Every week, companies in your field file, oppose and change counsel. It is all public, and almost none of it reaches the partner who knows them. LeadLex reads the EPO and the EUIPO against your client list and brings you the ones that touch it.
- 01 · The filing
New EPO filings from the companies you watch, every morning, next to their EU trade marks and the representative on each.
- 02 · The people
Linked to the people you already know there. Prospector finds the rest.
- 03 · A note, not a template
Short, in your voice, naming the filing and your actual history with them.
- 04 · Your call
It waits until you have read it. Change a line, or send it as it is.
Three sources, joined into one record.
Two of these you could buy, and so could the firm across the street. The third is the one that decides who wins the mandate, and no vendor can sell it to you. It is already sitting in your own mailboxes.
The IP registers
EPO patents with their representative of record, oppositions and legal events, and EU trade marks from EUIPO, joined to the companies already in your book. Coverage and status, register by register, are listed on the IP page.
270M+ business contacts
Across 480+ industries, covering in-house counsel, general counsel and IP managers, with deep coverage in the EU, the UK and the US. Searched in a sentence, not a query builder.
Your firm’s own history
Eighteen months of email with that client. Who introduced them. What was agreed in March. Which partner they actually pick up the phone to. Every firm already owns this, and almost none of it is anywhere a colleague could find it.
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.”

The "One Firm at a Time" Onboarding Model — Why LeadLex Doesn't Self-Serve

5 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 the firm is about to lose
Clients who have gone quiet and deals that have stalled, in front of someone before they become another firm’s mandate.
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.
Where the next hire should go
Which practices, sectors and sources actually produce mandates, measured in work won, not meetings held or cards collected.
Built for law firms. IP firms get the registers too.
Built for confidentiality from day one.
Nothing is sent to a client until a partner has read it and said yes. Any contact or matter can be walled off entirely, so a conflict never reaches Lexi in the first place. Every action is logged, with a name against it. Your firm runs its own isolated instance. Nothing is shared with another firm, ever.
GDPR
EU-hosted infrastructure (Frankfurt, Germany). GDPR-compliant, with a DPA signed for every firm.
ISO 27001
Built on ISO 27001 certified infrastructure (Supabase). Our own ISO 27001 audit is in progress.
SOC 2 Type 2
Built on SOC 2 Type 2 certified infrastructure (Supabase). Our own SOC 2 Type 2 audit is in progress.
No Model Training
Your data is never used to train any AI model. That is in the providers’ commercial terms, not a best effort.
Your own AI, not a shared one
Every firm runs its own isolated Lexi instance, with dedicated infrastructure, its own memory and its own credentials. Nothing is shared between firms, ever.
See it work on your own clients.
Forty-five minutes. We connect one mailbox and load your client list, and you watch it prepare the briefings, draft the follow-ups and show the patents and trade marks behind each company. Your own clients, not a sample account.
We take on a small number of firms at a time. Nothing is sent to a client until a partner has read it. Not this quarter? Join the waitlist.
