Professional Journey

Bailer’s recorded career runs through the finance function of fast-growing enterprise software companies. At DataRobot, the machine learning and predictive analytics platform, he served as vice president of finance while the organisation grew from roughly 200 to 1,200 employees, with revenue growing faster still. He then moved to Immuta, which sells data access control for cloud data platforms, where he led the finance team.

Solo.io announced his appointment as Chief Financial Officer on 8 March 2022, as part of a broader expansion of its executive team. At the time the company described itself as the application networking company delivering API infrastructure from the edge to the service mesh, and Bailer said he was joining a company “recognized as the leader in Istio service mesh and whose team roster includes a who’s who of open source luminaries.”

The business he oversees has moved with the market since. Solo.io now positions its products — kgateway, agentgateway and the Solo Enterprise offerings — around AI gateways and connectivity for AI agents as well as traditional service-to-service networking on Kubernetes, and in 2026 it has launched governance products for agents running in any environment and on the desktop. The company remains led by its founder, Idit Levine, and is based in Cambridge with a remote-first team.
