Blackletter is a radically different kind of law firm, redesigned to align with the needs and preferences of clients.
We work only on fixed fees, with no billable hours.
We deliver work quickly–moving at the speed of our clients.
And BlackletterOS retains a complete memory of every matter, enabling the firm to learn from its own work.
The result is superior legal counsel that is an enabler for business; not a tax on them.

Your law firm should make growing your business easier.
Before founding Blackletter, I spent years on the other side of the table as a client. I wanted lawyers who would understand what we were building, give us advice in that context, and move at our speed. Instead, they often made things slower, more complicated—and far more expensive.
Through my work at a frontier AI company, I began to see what could change. Technology could give exceptional lawyers far greater capacity—and more room to exercise judgment, solve difficult problems, and become deeply involved in their clients’ success. I saw an opportunity to build a firm around that potential.
This is Blackletter. Technology enables us to deliver the client experience that I’d always been seeking. Our lawyers’ judgment improves our technology, and our platform retains every piece of context and history, so we become a more capable and valuable partner with every engagement.
Law touches almost everything a business does. Improving how firms work - and broadening access to top-tier legal advice - will help companies build, invest, and grow with greater confidence. That is how we hope to help the economy work better.
We built Blackletter to be the firm I always wanted on my side of the table. Now we’d like to be that firm for you.

FOUNDING STORY
Building a Better Law Firm
Blackletter’s founders come from Big Law, management consulting, applied AI engineering and scaling a frontier AI company. Across several startups, they sat on the client side of the table, buying legal work from the world’s largest firms. They saw the model’s flaws up close: bills that grew with complexity, timelines set by the firm rather than the business, and expertise priced by the hour. They also saw what AI now makes possible: legal work that is faster and more accurate, done by lawyers freed from the busywork that consumes so much of their day. In 2026, they launched Blackletter: exceptional lawyers and frontier technology in a firm built to help move businesses forward.
