Who let the intern give a quote? 😅

@param_thakkar_ and I evaluated Opus 5 across a variety of redlining tasks. We saw significant improvements in NDA workflows, along with a major jump over Opus 4.8 in First Turn Accuracy on @crosbylegal's RedlineBench.

Contract negotiations are like poker games. The right answer depends on knowing your opponent, as much as knowing the law/rules. How good are frontier models at closing deals?

With @micro1_ai we benchmarked frontier models on multiple contract negotiations, across several turns. Rather than individual edits, we assessed the full sequence of judgment calls a lawyer makes across a deal lifecycle.

The headline: no model is close, and there are no standout winners yet.

Mary Barra joined General Motors as an intern when she was 18 years old, and worked her way up from inspecting car fenders and hoods to becoming the CEO.

Please welcome @crosbylegal's INSANE summer intern class. I can't wait to see which one of them takes my job.

Today we’re introducing Crosby, a hybrid AI law firm that helps rapidly growing businesses execute faster.

Contracts are connection points. They allow companies to transact with one another and create economic growth. But while every aspect of business has sped up, the way we negotiate contracts hasn’t changed in 50 years.

Crosby is building the API for human agreement. We combine the speed and intelligence of AI with the safety of lawyers-in-the-loop to review contracts in under an hour.

Since quietly launching in January, we’ve reviewed over 1,000 MSAs, DPAs and NDAs for some of the fastest growing companies in history, including @cursor_ai, @clay_gtm, and @unifygtm. Speed to execution is our north star, and today our median review time is 58 minutes. GTM teams call Crosby a secret weapon to close deals 80% faster. We’re just getting started.

Today, we’re also excited to share that we’ve raised $5.8m from @sequoia and @BainCapVC, as well as the founders of Ramp, Instacart, Flatiron Health, and others.

Crosby is a small, talent-dense team, combining lawyers from Harvard, Stanford, and Columbia Law with engineers from Ramp, Vanta, Meta, and Google. Every engineer on our team today is a former founder. We work in person in New York City.

If our mission resonates with you, we are looking for technologists, legal experts, and former founders to join us.

For high-growth companies looking to execute faster, we’ve opened up Early Access. Sign up on our website and we’ll be in touch.
