Reviews your product spec on every pull request
Reviews every pull request against the product specification and flags drift, inconsistency and misalignment before the code ships. It is a code review tool pointed at the product manager's problem rather than the engineer's.
That positioning is the bet. The buyer who feels the pain is the one who keeps discovering that what shipped is not what was agreed, but the tool has to be installed by the engineering team that caused it.
$1,028 bought 2,010 clicks, or $0.51 a click. Third cheapest traffic in the ledger, and the best return of any developer tool here by a factor of twenty against the worst.
