about us

A workshop for the world's oldest profession's hardest documents.

ZAAN is a small, profitable, privately-held company headquartered in Geneva and Shenzhen. We build software for lawyers — and for legal aid clinics, and for the people who never get a lawyer at all. The work is the same.

We started in 2022 with a question: why is contract review still done the way it was done in 1995? The honest answer was that nothing better had been built — yet. We've spent four years trying to answer that more carefully.

"We are not a rocket ship. We are a workshop with the doors open and the lights on late."
Our mission

To make rigorous legal work available to everyone who needs it.

Half our team is paid by the firms who use ZAAN. The other half is paid to give it away — to legal aid clinics, public defenders, and small-town solo practitioners across the world. We have no plans to change that ratio. We have plans to widen it.

What we hold to

Six things, closely held.

These shape the product, the hiring bar, and how we spend our time. They were written in the first year and edited twice in four. They probably won't change again.

01

Precision before polish

A legal tool that's almost right is wrong. We ship slowly and check our work. Shortcuts the user can't see are still shortcuts.

02

Simplicity without loss

Every interface decision removes something. We remove weight, never depth. Restraint is a feature.

03

Useful to the underserved

We give our platform free to legal professionals in developing regions. It's not a marketing line — it's why half of us are here.

04

Write, then write again

Clear writing is clear thinking. A memo that reads cleanly almost always has a cleaner architecture underneath.

05

Quiet ambition

We don't announce what we haven't finished. The work speaks; we try not to.

06

A small, permanent team

We hire slowly for people who want to stay. Growth happens inside roles as often as between them.

Founders

Three people, one long argument.

ZAAN was started by a magic-circle lawyer, a research scientist, and a product designer who'd built tools you've used. They argue often. They've never disagreed about why.

A

Amélie Roussel

Co-founder · CEO

Spent eleven years at Slaughter and May before becoming convinced the work needed better tools — and started building them. Reads four contracts a week, on principle.

K

Kenji Tanaka

Co-founder · CTO

Research scientist at DeepMind, then Anthropic. Believes the model is the easy part — the hard part is making the reasoning legible to a senior partner who has 90 seconds.

P

Pia Lindqvist

Co-founder · Chief Design Officer

Built design systems at Linear and at Notion. Holds the line on restraint. Has been overheard saying "less, but precise" more times than anyone has counted.

The team

42 people. And counting, slowly.

We hire roughly one person a month. Each one stays a long time. A representative slice of the people you'd be working with — engineers, lawyers, designers, researchers, and the ops team who keep the doors open.

A short history

Four years, told quietly.

We don't tell origin stories well — we don't really like the genre. Here are the moments that mattered, with the marketing varnish scraped off.

2022
February

Three people, one shared room.

Amélie, Kenji and Pia sublet a shared office in Carouge, Geneva. The first month is spent reading contracts and writing eval sets. No code is shipped.

June

First closed contract.

A boutique Genevan firm pays for a two-week pilot. The product is a Python script and a spreadsheet. The contract is for CHF 4,000. The team frames it.

November

Seed round.

CHF 6M from Stride.VC and Compound. Deliberately small. The team commits to never raising a round purely for headcount.

2023
March

Shenzhen office opens.

Three people, six months. Half the engineering team rotates through within the year. The cross-border M&A focus emerges from this office.

August

First hundred customers.

Mostly small firms in EU and SEA. Mostly from word of mouth. The team adds a single GTM hire — and only one.

December

Open Bar launches.

The free tier for legal aid clinics ships. By year end it has more weekly users than the paid product. We consider this a feature.

2024
April

Series A.

CHF 28M led by Index. Used to build out research, deepen the in-house Counsel models, and open a second engineering office. Headcount stays under 35.

September

Recall ships.

The third surface — semantic search across firm history — goes live. Two customers cancel competing platforms within the week. We do not announce it.

December

Profitability.

Cash-flow positive on the recurring book. The team takes a week off, deliberately.

2025
March

340 customers, 28 countries.

Cross-border M&A is now a quarter of revenue. Open Bar serves 4,200 paralegals in regions we cannot easily reach.

October

ZAAN-7B Counsel.

The first in-house model trained end-to-end for clause-level reasoning. It's small, fast, and good. The research team takes the rest of the month off.

Where we work

Three rooms, two timezones.

Most of the team works in Geneva or Shenzhen, with a small remote contingent across Europe and South-East Asia. The offices are quiet and well-lit. Phones rarely ring.

Capital with long horizons.

We chose investors who don't ask us to behave like a rocket ship. They've all been founders themselves, they all understand the work, and they all read the contracts we send them carefully.

In the press

What others have written. Selectively.

We don't court press, and we won't comment on rumour. These are pieces we found thoughtful enough to link to.
