Questions & Answers

As answered by people managing ProtoPie and Sourcey.

What makes your product unique?

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.

How would you describe the primary audience of your product?

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.

Why should a person choose your product over its competitors?

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.
