Questions & Answers

As answered by people managing Langfuse and Provek.dev.

What's the story behind your product?

Provek.dev's answer:

Anyone can write "AI-powered" on a landing page, and nobody can tell that apart from a business that machines actually run. I wanted a way to check the claim per operation, with the evidence in the open and the method public. Provek is the result. It works as an ERC-8004 validator: the standard gives identity and transport, and the methodology is ours.

Which are the primary technologies used for building your product?

Provek.dev's answer:

Python for the measurement and registry, TypeScript with Preact and Vite for the site, Tailwind CSS, Cloudflare Pages for hosting, and ERC-8004 for identity.

What makes your product unique?

Provek.dev's answer:

Provek scores each business operation on its own, from L0 to L5, and never gives one number for the whole company. Evidence is ranked by how hard it would be to fake. When Provek cannot measure something, the passport says why instead of writing a zero. The method is public, so anyone can recompute a verdict from the same inputs.

Why should a person choose your product over its competitors?

Provek.dev's answer:

Most claims about AI-run businesses are a line on a landing page. Provek checks them from the outside, anonymously, and shows the evidence next to every number. It also shows its own gaps. If you want a claim you can check, that matters more than a badge.

How would you describe the primary audience of your product?

Provek.dev's answer:

Founders who run parts of their business with AI agents and want a public, checkable record of it. Also buyers, partners and investors who need to tell a real automated operation from marketing copy.
