Opportunity score
58/100
A clean, well-positioned developer API with a real use case, but it sits in a crowded, low-margin, easily bundled infrastructure niche.
Founder verdict
MAYBE
Epho is a beautifully simple API for coding agents, but it is an infrastructure race, not an obvious standalone business yet.
What is Epho?
Epho is a developer-facing API service that runs coding agents (Anthropic's Claude Code, OpenAI's Codex, and open-source OpenCode) in fresh cloud sandboxes. A caller sends one JSON POST to /api/v1/chat with a prompt, optional repos, input files, MCP servers, env vars, and provider key; Epho boots the sandbox, clones repos, starts the chosen agent, and streams tokens/tool calls/diffs back over SSE. It also supports async jobs, durable multi-turn chats with session snapshots, persisted event replay, and presigned artifact downloads. Observed pricing is metered per-second for compute, memory, and disk only; model tokens are not billed by Epho because customers bring their own provider keys. No revenue, growth, team size, or customer proof is disclosed on the site.
