A new way to diligence.
Agents replicate the product in minutes. You get the real cost to rebuild - compute, humans, go-to-market.
How It Works
From URL to replication blueprint.
01/Fetch
We scan the target product and retrieve content, assets, and surface area.
02/Extract
Agents identify features, integrations, and technical dependencies.
03/Score
A defensibility score from 1 to 100 with feature-level build estimates.
