In-house floor engine vs vendor (Assertive/Pubguru): build vs rent the brain

In-house floor engine vs vendor (Assertive/Pubguru): build vs rent the brain
Heard: bigger pubs flirt with building floor optimization in-house to keep the margin and the data.
— Vendor: live in weeks, trained on cross-pub data, but they take a rev-share and see your numbers.
— In-house: full data ownership, no rev-share, tunable to your exact contexts — but you need an ML person and months of log-level training data.
— Vendors win on cold-start; in-house wins at scale once you have months of clean auction logs.
Impact: Under ~$200K/mo programmatic, rent it. Above, the rev-share funds a hire who'll beat the vendor on your own data. (sourced)
