## Company

- Ownership: independent
- Stage: pre-seed [source](https://www.cbinsights.com/company/warpbuild)
- Accelerators: Y Combinator Summer 2021 [source](https://www.ycombinator.com/companies/warpbuild)
- Total raised: $2M (estimated: Aggregator startupintros.com puts the single Aug-2021 round at $2.0M with 8 named investors; aggregator indexed.vc instead reports $1.5M for the same 'Angel' round; Crunchbase shows the amount as obfuscated (paywalled). No company/press primary source found, so the figure is not company-confirmed.) [source](https://startupintros.com/orgs/warpbuild)
- Last round: pre-seed, $2M, 2021-08 (estimated) [source](https://startupintros.com/news/2021-08-01-warpbuild-seed)
- Investors: Y Combinator, Quiet Capital, AIX Ventures, Atreides Management, Chemistry VC, O'Shaughnessy Ventures, Positive Sum VC, C2 Investment, Launchpad Venture Group, Randall Lloyd
- Revenue: $1M (estimated: Getlatka third-party estimate based on an interview with WarpBuild's CEO) [source](https://getlatka.com/companies/warpbuild.com) ARR, 2024

WarpBuild (Surya Oruganti, YC S21) provides fast GitHub Actions CI runners (Linux/macOS/Windows, x86-64 and arm64) plus newer AI-agent-runner and Helios workflow products. Only one small priced round is publicly documented (~2021, disclosed as Pre-Seed by Crunchbase/CB Insights but as a $2M 'Seed' by other aggregators); no primary press release or company statement confirming the amount was found, and no subsequent round has been reported through 2026. Getlatka quotes the CEO saying the company grew to ~$1M ARR largely on its own revenue rather than follow-on VC funding.

## Caveats

- CI-runner-only product (all modes flagged alt): machines exist only for a GitHub Actions job; not an interactive or agent sandbox.
- Add-ons: cache storage $0.20/GB-month, cache write/restore $0.0001/op, snapshot restore $0.04/job, snapshot storage $0.025/hour per snapshot (~$18.25 per snapshot-month) — not per GiB, so snapshot_gib_month is null.
- BYOC (your AWS/GCP/Azure): $0.002/min per Linux or Windows runner on top of your own cloud bill; not modelled.
- Docker builders ($0.06-$0.88/min) not modelled.
- Free usage amount not published.
- macOS on Apple hardware: Apple macOS SLA: leasing a Mac requires a minimum lease of 24 consecutive hours with sole use by the lessee, and allows at most 2 additional macOS VMs per Mac.
- Card category is "macos" only because the schema has no CI category; every regime sets product_class "ci-runner" and an explicit os, so Linux/Windows runners are not treated as macOS. All regimes keep flag alt (CI minutes); the engine ignores alt when the workload is shopping for a CI runner.
- Snapshot runners: snapshots are auto-deleted after 15 days, so one retained snapshot costs at most ~$9 (360 h x $0.025) unless refreshed.
- SSO (SAML 2.0 or OIDC) is now self-serve from Settings -> SSO at $250/month, billed after the first domain is verified (was enterprise-contact).
- Removed on 2026-06-08: WarpBuild Cloud spot runners, Windows 2 vCPU runners, macOS 13, custom cloud runner configurations (spot now BYOC-only).
- macOS memory: 6 vCPU = 22 GB and 12 vCPU = 44 GB until 2026-09-30; from 2026-10-01 14 GB / 28 GB at unchanged prices (card already uses the post-change values).
- Docker builders auto-scaling in private beta (2026-09-25); prices unchanged $0.06-$0.88/min.

## How this provider charges


WarpBuild sells GitHub Actions runners (Linux x64/arm64, Windows x64, macOS M4 Pro, Linux on Apple Silicon), billed **per minute** with unlimited job concurrency. You can also bring your own cloud (BYOC). It is CI-only: all card modes are flagged `alt`.

## Gotchas

1. **Windows costs 2× Linux x64 per size;** macOS costs 10× Linux x64 for comparable vCPU.
2. **Snapshots are billed per snapshot-hour** (≈ $18.25/month each), not per GiB.
3. There is free usage for new accounts, but the amount is unpublished.
4. Machines live only for a job. There is no interactive/agent use.

## Worked example

Workload: 4 vCPU / 8 GiB for 8,800 h (as if it were CI minutes). One snapshot is kept, and egress is not priced.

| Regime | Size picked | Maths | Monthly |
|---|---|---|---|
| macOS | 6/14 | 8,800 × $4.80 | **$42,240** |
| Windows | 4/16 | 8,800 × $0.96 | $8,448 |
| Linux x64 | 4/16 | 8,800 × $0.48 | $4,224 |
| + 1 snapshot | – | 730 × $0.025 | +$18.25 |
