We started NatorOS because the gap between what AI agents could plausibly do and what they actually did inside a company was enormous, and the gap was not a model problem. It was an operating-system problem.
Today we are announcing $80M in Series B funding to keep building that operating system. The round was led by Founders Fund and includes participation from our existing investors at Sequoia and Index, as well as a group of operators we have learned from for two years.
Two things became clear in our first year of customers:
NatorOS sits between those two needs. The operator authors a workflow in plain language. The engineer refines the boundaries and approvers. The runtime owns memory, permissions, evals, audit, and replay. Together it produces an AI worker that a CIO can sign off on.
