We raised $24M to make AI agents accountable
Our Series A, led by Northbeam with participation from existing investors, will fund self-hosted deployments, a European region and a lot more evals.

Why now
Two years ago, AI agents were demos. Today they process refunds, triage incidents and write production code. The tooling to understand what they’re doing — and to prove it to customers and regulators — hasn’t kept up.
We started Sable because we were the engineers getting paged when agents misbehaved, with nothing but log lines to go on. Today, more than 600 teams use Sable to trace, evaluate and guard their agents in production.
What’s next
This round lets us ship self-hosted deployments for regulated industries, open an EU data region, and double our research team’s work on trajectory evals. We’re also hiring across engineering, research and go-to-market — come build with us.
