Agent 37 launches at YC (Fall 2026)

Agent 37 runs coding agents as always-on hosted sandboxes, so you host neither the machine nor the state. One POST to /v1/instances provisions an isolated environment with its own URL that you can message across sessions; files, memory and connected tools stay put until you delete it. It runs Hermes, OpenClaw, Claude Code, Codex or a custom harness, in 2-8 vCPU / 4-16 GB sizes, with gVisor kernel-level isolation, encryption at rest and in transit, and SOC 2 Type I. There is no plan fee — compute meters by the minute at $0.0011 per vCPU-hour and $0.00096 per GB-hour of RAM, which puts a continuously running 2 vCPU / 4 GB sandbox near $4.76 a month. Founded in 2026 by Vishnu Krishnaprasad, based in New York City.
