Join us in building
the future of legal work

The legal industry is changing beyond recognition, and Crimson is at the forefront of this change. We're building the AI platform that will define the future of litigation.

Why Crimson?

Funded to Win

We're backed by some of the world's leading investors, including top seed funds such as Y Combinator, as well as partners and legal tech experts at some of the most renowned law firms.

Elite Customer Base

We're working with litigation teams at elite US and UK firms on complex cross-border disputes. They use Crimson on a daily basis – it's transformed the way they run their cases.

Top Performers

Our team combines exceptional technical ability, deep legal expertise and limitless ambition. We're building a category-defining company that is reshaping the legal industry.

The Highest Calibre

We're extremely selective, with an acceptance rate of <1%. We're looking for extraordinarily talented, high-agency individuals who share our ambition and work ethic.

The opportunity

Litigation is fundamentally about working with text – analysing evidence, reviewing arguments, drafting submissions. LLMs are perfectly suited to transform this work, and we're among the first movers in this space. We're vertically focused on disputes, executing fast, and have built significant traction just months after launch. The opportunity ahead is enormous.

Ship at extraordinary speed

Your work goes directly to litigation teams at the world's top law firms – often within days. The feedback loop is incredibly tight, and your impact is immediate and visible.

Work with the latest AI

You'll use the most advanced AI models daily, pushing the boundaries of what's possible with LLMs in production. Real applications for billion-dollar disputes.

Shape the product directly

You'll speak directly to partners and associates at elite law firms, understand their workflows, and build solutions for their most pressing problems.

Full ownership and autonomy

From architecture to deployment, you'll own entire product areas. We trust exceptional people to make decisions and move fast.
