no sale observed
This is the largest amount Spy has ever observed on PenPool’s own public pages. Read it as a floor. It is not revenue and it is not profit, and money taken before Spy started reading is not in it.

The 3 businesses on this ground with the most money observed. Open any of them and read its file. What each one charges, what it promises and how it asks for the money is what the audit reads.
The audit of PenPool
PenPool has no sale on the record. The audit says whether the ground under it is empty or unasked.
Everything above is free and counted. The audit is written: the market it sells into, the buyer who pays, the 3 beliefs blocking that sale, what its 5 nearest rivals charge and promise, the offer that would take the ground, and the one move to make in 24 hours.
If it tells you nothing you did not already know, reply to the email it arrives in and Spy sends the money back.
The free audit is the whole file on CVBoost, written the same way, with nothing removed. Read it before deciding whether this one is worth $9.
Advertising
No advertising observed. Spy reads Meta’s public ad library across the whole platform, and nothing in it points at PenPool.
