Partner and I built a service to do sales attribution and commissions, ingesting data from Shopify / WooCommerce / etc. Works great for any sort of sales organization w hierarchy, but we’ve had success with network marketing / direct sales.

Spending nights and weekends, we scaled enough that we banked about $67k on the side in the first 8 months and then took used that as seed to go full time. 3 years later we’re still at it with a decent team and a ton of fun and cool tech
