Summary

Bay launched with $50 million to inventory AI agents and vet their actions before they run.

Tap a passage. React to the part that matters.

A new security startup, Bay, launched with $50 million to check every action an AI agent attempts.

Bay AI launched November 10, 2026, with $50 million across a $37 million Series A led by Battery Ventures and a $13 million seed, selling software that inventories AI agents across a company and vets each action before it executes.

The product installs through the mobile device management or endpoint detection tools a customer already runs, then tracks agents wherever they sit: on an employee's laptop, inside a cloud workload or inside a SaaS application. The $37 million Series A was led by Battery Ventures, with Micron's venture arm participating; the $13 million seed was co-led by YL Ventures and Striker Venture Partners, and Wiz chief executive Assaf Rappaport invested personally. The customer list is the credibility claim: dozens of enterprises signed in the nine months since the company was founded, including Micron, which started as a customer before investing, plus Wix, ClickUp and Peloton.

Co-founder and chief executive Yuval Zacharia's pitch names the pressure creating the market: security leaders are handed an enterprise-wide AI rollout with a year-end deadline, and the control question changes shape. Access control asks who may enter a system; agent governance asks what an autonomous program does once it is inside, at machine speed, across dozens of tools at once. Bay's answer is a gate in front of the action rather than an audit after it, a checkpoint on each attempted step. Whether enterprises will pay for a dedicated agent-vetting layer, rather than waiting for the platforms to build one, is the bet the $50 million is riding on.
