ABOUT LEGALQUANTS

1. What is our mission?

LegalQuants exists to find, vet, train and deploy legal quants. We do this by building the ecosystem and infrastructure needed to support this new category of talent.

2. What is a legal quant?

Short version: A lawyer who builds their own tech to practise law.

Long version: A lawyer who builds their own system like a quant to encode, scale and distribute their legal expertise, and who captures the economic value of doing so.

3. What's the origin story of LegalQuants?

LegalQuants began in November 2025 as a WhatsApp group. There were just a handful of people in it, pulled together by Jamie Tso after he kickstarted the vibe-coding movement. He organised two hackathons with Manus and Replit in rapid succession, and it drew in like-minded, highly talented lawyers who were building. Most of them had been building alone, and the group was the first place they found each other.

The market did not see it that way. It dismissed this category of talent as “vibecoders” and “cowboy lawyers” and judged their work against production software on security and maintainability. But after a conversation with his high school friend, who used to work at Jane Street as a developer, Jamie came to the realisation that the dichotomy between “lawyer-built tools vs vendor-built tools” was the wrong frame. What mattered was lawyers who scale their own judgement with AI and capture the economic value of doing so. On 15 January 2026 he published the seminal essay “The Jane Street of Law: The rise of the Legal Quant” and named the category. “Legal quants” is now an industry term, used by leaders including Norm AI CEO John Nay to describe their lawyers.

Jamie met his co-founder Raymond Sun in that same WhatsApp group. He considered Raymond the original legal quant. Raymond had solo-built the Global AI Regulation Tracker to 70k+ users, which became the most wanted connector for the Claude for Legal plugin.

The two met in person for the first time in Tokyo in May 2026. Over several days they agreed to make it their mission not only to let legal quants find each other, but to let the market find them. LegalQuants was formally incorporated as a private company in mid-April 2026 and set out to build that market.

The LQ Residency (launched in May 2026) is the first iteration of what that market looks like for legal quants, where experienced legal quants are paid to teach fellow lawyers how to build their own tools. As of today, LegalQuants remains a bootstrapped company and has paid more than US$120,000 to legal quants through the LQ Residency.

4. Who runs LegalQuants?

LegalQuants is run by its two co-founders, Jamie Tso and Raymond Sun. There are no employees. We periodically invite distinguished members to serve as mentors on the LQ Residency, which is a paid role for the duration of a cohort. Mentors speak for their own work, not for LegalQuants. We have not appointed regional, community or practice leads.

5. What has LegalQuants built?

Money now reaches legal quants because LegalQuants exists. Through the LQ Residency, mentors are paid for their expertise.

Beyond the Residency we run LQ Assess, the observed work session used as the admissions floor; LQAI and other open-source work by members; and the editorial products, LQ Digest and LQ Brain. LegalQuants is an open-source contributor to Anthropic's Claude for Legal plugin and OpenAI's ChatGPT-for-Law plugins.

6. How do I become a member of the LegalQuants community?

There are three routes in: complete the LQ Residency, pass LQ Assess, or receive an invitation from Jamie Tso or Raymond Sun. There is no certified Legal Quant or LQ designation at the moment. We charge no membership fee, so membership is maintained by contribution rather than payment: taking part in LQAI or other LQ Labs build initiatives, contributing to LQ Assess benchmark tasks, and generally advancing LQ's mission. Members who have not contributed for an extended period will be removed to make room for more active members.

7. Who is a member and who is not?

A member of the LegalQuants community is someone admitted through one of those three routes. You can browse the public directory at legalquants.com/community. Some members are stealth and do not appear there, so absence from the directory does not by itself mean someone is not a member. To verify anyone, write to admin@legalquants.com.

A member of the LegalQuants community is not a LegalQuants employee, contractor, agent or spokesperson. We find and vet legal quants at the point of admission. We do not supervise, endorse or warrant any member's work for a client, and admission is not a professional qualification or a certification.

8. How can I work with LegalQuants?

If you are an aspiring legal quant, see question 6 for the ways in.

If you represent a law firm or an in-house team, we can train your lawyers to become legal quants through the LQ Residency. Where you would rather hire than train, we run a targeted search across the membership. Write to admin@legalquants.com and tell us what you are trying to solve.
