YC directory confirms Sieve (W22, Active, founded 2022, San Francisco) shares the domain sievedata.com used by the card, so the hint is verified as the same company. The company pivoted from a developer video-processing API/compute product (its 2022 launch) to a 'multimodal data lab' selling curated datasets/environments to frontier AI labs via purchase agreements, matching the card's caveats about the former compute product being discontinued as a public self-serve offer. No priced round after the Nov 2022 ~$4M seed was found in the time available; total funding and stage should be treated as potentially stale given the 2024-2026 pivot and continued 34-person team.

## Caveats

- Discontinued or closed to new customers, confirmed on the live site 2026-09-29. Official March 4, 2026 reintroduction confirms the pivot from video APIs to end-to-end datasets. Current homepage is a multimodal data lab; /pricing returns 404. The company is active, but the card’s former compute/API product is discontinued as a public self-serve offer.
- YC and current homepage position Sieve as a multimodal data lab. Former developer compute may be legacy; current /pricing returns 404. Do not reuse historical per-GPU rates as a current offer.
- Inventory exclusion: pivot; current general code hosting unverified. 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. YC and current homepage position Sieve as a multimodal data lab. Former developer compute may be legacy; current /pricing returns 404. Do not reuse historical per-GPU rates as a current offer.
2. Inventory exclusion: pivot; current general code hosting unverified. 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.
