Worth knowing
- Thoma Bravo closed its roughly $8.0B take-private on 2023-02-28; Coupa is no longer listed on Nasdaq.
- Supplier risk (Risk Assess) came from the 2018 Hiperos acquisition, so it is an acquired module rather than native to the core procurement app.
- Costbench data shows auto-renewing contracts with a 1 to 3 year minimum and about 23% average negotiated discount, so list price is not the paid price.
