The challenge: a venture case in a crowded category
A pre-launch company founded by lawyers, in a category investors think is already won.
The category. Legal AI is one of the best-funded corners of software, and the biggest rounds go to tools built for law firms.
The material. It read like a legal opinion: detailed, cautious, every claim hedged, and numbers with no ambition in them.
The story: the segment the giants left open
The biggest names in legal AI sell to law firms. This company sells to the businesses those firms bill.
Legal demand keeps rising and courts get slower every year. The cost lands on the companies this product serves.
What we learned: what fails in legal AI at pre-seed, and what gets funded
Investors have already picked their favourites. Everything else needs proof on the page.
Why legal AI struggles at pre-seed
What gets funded
Vision-only decks.Investors want traction or top credentials, and proof for everything else.
Workflow depth.A multi-step, judgment-heavy task handled end to end.
The wrapper question.If it looks like a prompt around a general model, the meeting ends.
A route to the first hundred customers.With the channel already identified.
An unclear buyer.Money goes to tools for big law firms; anything else must name its buyer.
Willingness to pay.Pilots, letters of intent or signed contracts, even small ones.
Liability.Investors ask how it avoids getting things wrong before they ask about growth.
Capability with control.Human sign-off, an audit trail and clear governance.
What the deck shows investors
Three slides carry the case: the product, the gap in the market, and the numbers.
The product as agents, with a lawyer in the loop.
How the agents cut the time from a claim to a court-ready draft, with lawyers in control.

The segment the giants left open.
A competitive map built for businesses rather than lawyers, with the owned channel to reach them.

Numbers with ambition that hold up.
Revenue, margin and payback to 2031, from a model built to test whether the economics hold.

What we did: six pieces, one company
Six jobs on one timeline, delivered as one system.
Narrative
From a legal brief to a venture story: hedges out, ambition in, every claim defensible.
Financial model
Built from scratch to set pricing, launch order and a growth pace the company can sustain.
Investor deck
Why now in numbers, the product, the owned channel, the team and the £1M ask.
Rebrand
Serious enough for a general counsel, with the energy of a tech company.
Website
The problem, the product, the team’s credentials and a clear way in for buyers.
Sales deck
What a legal claim costs the buyer, and what the agents take off their plate.
