BuildJet for GitHub Actions (co-founders Adam Shiervani and Lian Duan) is a YC W23 company, listed as 'Active' on YC's own directory as of the check date, but the product itself has shut down: the company announced on 2026-02-06 that 'BuildJet for GitHub Actions is shutting down', stopped new signups immediately, and stopped running jobs on 2026-03-31, 2026, directing users to migrate to GitHub's own hosted runners. The homepage now reads 'BuildJet for GitHub Actions has been shut down.' No funding round, total funding, or revenue figures were disclosed anywhere found (YC page, company blog/pricing/about pages, or web search).

## Caveats

- DISCONTINUED: buildjet.com/for-github-actions reads "BuildJet for GitHub Actions has been shut down" (checked 2026-09-28). Regime flagged legacy so it is never priced.
- Official homepage says BuildJet for GitHub Actions has been shut down, despite YC Active. Historical 4-vCPU/16GB rate $0.008/min and $300/month per extra 100 concurrent vCPUs are retained as historical only; do not auto-rank a discontinued service.
- Inventory exclusion: officially shut down. Card contains no numeric compute modes and no selectable price plan.
- 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. Official homepage says BuildJet for GitHub Actions has been shut down, despite YC Active. Historical 4-vCPU/16GB rate $0.008/min and $300/month per extra 100 concurrent vCPUs are retained as historical only; do not auto-rank a discontinued service.
2. Inventory exclusion: officially shut down. Card contains no numeric compute modes and no selectable price plan.

## 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.
