Our Partners
Stinky Cactus runs on technology from Cactus Wash Systems — the team behind MonsoonOS and Rain Pay.
Cactus Wash Systems
The wash-technology company behind Stinky Cactus. Cactus Wash Systems builds the software and payment hardware that keep our stations humming — for dog washes and car washes alike.

The operating system for the whole wash. MonsoonOS powers the Stinky Cactus app, Wash Club subscriptions, and the machines themselves — it's how you pick a station, match the cactus icon, and start washing in seconds.
Rain Pay
Tap-to-pay at every station. Rain Pay is the integrated payment terminal on each machine — tap, dip, or swipe your card and wash without needing the app.
