YC hint confirmed: Y Combinator company page for 'Release' (slug release, W20/Winter 2020, status Active, website https://release.com) matches the card's domain (release.com/pricing) exactly — same company. Founded by Tommy McClung, Erik Landerholm, and David Giffin (ex-TrueCar). Product pivoted/expanded from staging-environments-as-a-service (ReleaseHub) toward an AI infrastructure/sandbox orchestration product (Release.ai / AI Sandbox API), per a 2024 Launch HN post, while keeping the original EaaS/dev-environments business. No funding round found after the Oct 2021 Series A as of 2026-09-30; no public revenue/ARR figure found.

## Caveats

- Chrome pricing confirms only Enterprise runs in customer AWS/GCP cloud, custom negotiated platform price. Includes ephemeral, preview, production and cloud dev environments, CLI/API, GitOps, docker-compose, Terraform/Helm, enterprise SSO and unlimited clusters. Underlying infrastructure costs remain separate; no public all-in sandbox price.
- Null values mean unknown, not free/unlimited. No model-token cost, tax or unverified ancillary charge included.
- Native browser/device/task/credit prices with unknown CPU/RAM are deliberately non-priceable. Check regime before interpreting any partial resource estimate.

## Verified billing facts and gotchas

1. Chrome pricing confirms only Enterprise runs in customer AWS/GCP cloud, custom negotiated platform price. Includes ephemeral, preview, production and cloud dev environments, CLI/API, GitOps, docker-compose, Terraform/Helm, enterprise SSO and unlimited clusters. Underlying infrastructure costs remain separate; no public all-in sandbox price.

## Worked example

Requested: 4 vCPU/8 GiB, 50 simultaneous × 8 h/day × 22 days = **8,800 instance-hours**, 30% CPU; 50 GiB snapshots and 100 GiB egress. A month is 730 hours only when explicitly used in rate conversion.

**Total: unknown.** This product does not publish a verified complete 4-vCPU/8-GiB tariff and/or the service bills a different unit. Fifty concurrent instances and eight-hour sessions are not automatically supported. Neither 30% utilization nor retained snapshots can be converted into free resources. Use the native plan terms above and request the missing CPU/RAM, retention, egress and concurrency quote.

Page captures and documentation indexes/bundles are in `raw/`; provider JSON lists the evidence paths. HN query results were captured separately as `<id>--hn.txt`; they are discovery leads, not current tariff authority. Downloaded docs do not imply every feature was verified; unsupported assertions remain null.
