My co-founder Prateek and I have been building Coasty (coasty.ai), isolated cloud VMs purpose built for AI agents.
The problem we kept hitting: most cloud providers weren't designed for agents. Sandboxing is either overkill or nonexistent, and you're paying for always-on compute when agents are inherently bursty. We wanted something that runs in true isolation, and doesn't charge you for idle time. So we built it. Full VM isolation per agent run, and pricing that actually makes sense for agentic workloads.
We're two CS students (Columbia and Purdue Engineering) who got frustrated enough to build the thing ourselves. We have paying customers and ~700 people on the waitlist, which tells us we're not the only ones annoyed by this. We even ran the OSworld test for agents(completed 82% of the 369 automation tasks thrown at it).
Still early but love to hear brutal feedback, especially from anyone running AI agents in prod who's dealt with this.
