As answered by people managing Velt and Sourcey.
Sourcey's answer:
Sourcey ties startup offers and Agent Readiness findings to source evidence and versioned releases. A report card describes one agent task, its observed result, blockers, and unknowns. Offer records keep the vendor’s terms and eligibility caveats visible. The public record is free to read through the website, JSON, API, and MCP.
Sourcey's answer:
Founders comparing startup offers, developers evaluating whether an agent can complete a specific task with a service, and agents that consume the public record through HTTP or MCP.
Sourcey's answer:
Choose Sourcey when you need the original source behind an offer or a task-level account of what an agent could actually do. It shows uncertainty and release history alongside the finding. Sourcey does not apply for offers or redeem credits on a founder’s behalf.

Velt lets you skip all of that. You plug it into your app and get comments, presence, notifications, and shared context immediately. You don’t worry about syncing users or handling concurrent updates. Your code stays focused on the UI... - Source: dev.to / 5 months ago
Sourcey is an attempt to fix that by putting the record in public, with the receipts. It is an open registry of startup credit programs and of agent-readiness report cards, built to be read by machines first: an anonymous HTTP API with a... - Source: dev.to / 2 days ago
For example, from the Sourcey agent-readiness release Release_id sha256:371cbf65650abf5756c967b1f1da9df607be4b1bb0c0b93aaf2dcf0a36e75d3e (artifact_sha256:67c4edef061ca4ea60cef1e1bc246d2ce0b7d6b12e227c0811d7405d3d0a63ac, Effective... - Source: dev.to / 4 days ago
Doing all this by hand for every candidate got old fast, so now I lean on Sourcey, a registry that tracks exactly this. It publishes report cards that grade whether an agent can actually sign up, pay, and operate a service on its own,... - Source: dev.to / 16 days ago
