Red Bear Angels portfolio company Fiveonefour has launched AX Cloud, a managed platform for experimenting with agents as users. The service lets product teams define experiments, select agents and models, and run isolated simulations locally or across cloud infrastructure.
AX Cloud captures agent transcripts, telemetry, errors, commands, timelines, and sandbox state so teams can compare variants and turn evidence into product decisions. The company positions the platform as a way to test agent discoverability and usability before releases, with workflows that can feed results into pull requests and release gates.
Fiveonefour’s launch reflects a broader shift toward treating AI agents as a distinct user group with measurable experience requirements. The platform is designed to help developers understand and improve those interactions systematically.
