Launch HN: Runtime (YC P26) – Sandboxed coding agents for everyone on a team
Not a pilot. A fintech unicorn just deployed coding agents across reconciliation workflows—and Runtime is the infrastructure making it safe for non-engineers to ship.
Why it matters
Runtime solves the organizational bottleneck of agentic coding: how to let non-engineers safely use Claude Code, Devin, and other agents without engineering overhead, secrets leaks, or unmergeable PRs. Early customers include fintech unicorns and YC scaleups doing real work (on-call automation, financial reconciliation) in production.
The key facts
14 to knowRuntime YC P26 startup shipping sandboxed coding agent infrastructure
Founders: Gus (ex-Mentum/YC S21), Carlos (ex-Modern Treasury agentic systems)
Works with Claude Code, Codex, Cursor, Copilot, Gemini, Devin
Environment snapshots include multi-service Docker Compose, Kafka, Redis, seeded DBs—millisecond startup
Orchestrates across E2B, Daytona, EC2, self-hosted K8s
Infrastructure-level guardrails: command allow/deny, network egress controls, RBAC per human/agent
Secrets injected via managed proxy—never touch agent directly
Customer case: on-call inspector wires PagerDuty + Sentry + repo, agent finds cause and opens PR before page
Customer case: finance agent in private Slack channels reconciles Stripe/NetSuite/Snowflake in minutes
Live customers: fintech unicorn, several YC scaleups (some migrated from internal infra)
Core open source at github.com/runtm-ai/runtm
Hosted version live at app.runtm.com with free tier

Publisher excerpt: Hey HN, We're Gus and Carlos from Runtime (https://runtm.com). We're building infra that lets your whole team (including non-engineers) ship with Claude Code, Codex, and other agents without engineering having to handhold every session. After Mentum (YC S21) was acquired, I personally shipped 4…
