The AI Law Firm Built for Execution. Lawyer-assisted AI to review MSAs, DPAs and NDAs in under an hour.

NYC
We won't bill you by the hour. And sometimes, we'll even throw in flowers! Our team handed out 400 bouquets in Union Square to mourn the death of the billable hour and celebrate the launch of our NYC out of home campaign across Union Square, Flatiron, Soho, and the subway.

With 12 engineers supporting 50+ attorneys, @crosbylegal put Devin on first response. Devin investigates 20–40 bugs and alerts a day, cut Sentry noise by 50%, and kept on-call to one engineer as the legal team grew 5x.

At @crosbylegal we see a future where you aren't nervous to email your lawyer. How many $1000s will that cost? When will I hear back? That future is already here. LLMs are the greatest thing thats ever happened to our profession. Excellent legal work can be delivered at a fraction of the old speed and cost. So how is it possible that law firms are still billing by the hour? Our profession can do better. It must.

RIP the billable hour. It will be remembered fondly by everyone who charged it, and by no one who paid it. In lieu of flowers, send contracts to crosby.ai

Obviously this PR stunt was unreasonable. We aim to be the most reasonable law firm in the world. In the world of AI, that starts with laying billable hours to rest.

For the first time today, I was on the other side of receiving redlines from a @crosbylegal customer. The redlines were clear, sensible, and had succint comments attached for each change. A lovely experience as a counterparty.

To a tee. In my latest piece on @crosbylegal I dug into @jsarihan and his ethos of bias toward speed, and breaking down complex problems into “little brick walls that you can run through.” Much of which he credits learning from @karimatiyeh from @tryramp!
5 minutes into meeting John he told me he wanted to start his own company. I told him Ramp was the best place to learn first. He took that seriously- built 0->1 products, ran hiring processes, operated like a founder from day one. A real builder and extremely high slope. Now Ramp is a Crosby customer. We're defined by speed and Crosby is the first law firm that actually matches it. Not surprised at all!

We don’t talk much publicly about what we’re building internally. Our main goal is for lawyers to review an agent’s work, rather than redline themselves. The better the agent is, the less time a lawyer spends reviewing its work. Last quarter we finally hit a longtime goal: “the 5 minute NDA review.” We’re the first company to reliably achieve this. Here's how we solved a category of difficult NDAs. Sharing a slide from our last board deck:
Crosby (@crosbylegal) is a “neo-firm," equal parts lawyers and engineers that owns liability, and takes on legal work end to end, handling contracts for @ramp, @clay, @cursor, @cognition, @ListenLabs and more. I spent two weeks embedded in Crosby in New York - seeing their time trials (internal contests where lawyers race to redline a contract), All Hands, eng meetings, hung out in their Slack. I even shadowed lawyers. Over 25 conversations later, I'm excited to share this field study going deep on solving unverifiable problems in law, profile on @ryanjdaniels (Stanford-trained attorney) & @jsarihan (early employee at Ramp), and how "misfit lawyers" feel about the role of the lawyer changing.
