Bay emerged from stealth with $50 million in total funding. The company raised a $37 million Series A led by Battery Ventures. Bay builds an AI security platform that helps enterprises control autonomous AI agent actions.


Funding details

The Series A attracted Micron Ventures, M12, and Wiz CEO Assaf Rappaport. The seed round was led by YL Ventures and Striker Venture Partners. Bay disclosed the funding less than a year after founding.

Enterprise traction

Bay has dozens of enterprise customers. They include Micron, Peloton, ClickUp, and Wix. The company says Fortune 100 companies used its platform to triple autonomous AI agent use.

How the platform works

Bay monitors proposed AI agent actions before execution. It enforces policies across devices, cloud infrastructure, and SaaS applications. The platform deploys in under five minutes without extra endpoint agents or proxies.


Bay is available to enterprises today. It plans to use the funding to expand product and engineering teams. The company will also grow sales, marketing, and customer teams in the US and Europe.
