Erikas funded and launched Kaching Bundle Quantity Breaks using the money and experience from selling an earlier Shopify app (a product icons/guarantees app) for $250K.

“We have sold this app at $6700 MRR for $250K.”

In the Indie Hackers interview about the current Kaching app portfolio, Erikas describes seeding early users by posting the app for free in Shopify dropshipping Facebook groups; some posts went semi-viral and pushed the app onto the Shopify App Store trending list, reaching 1,000 users in the first month. The interview does not name which specific app this refers to, though it is presented as describing the current flagship.

Merchants who first installed for free later converted onto paid usage-based tiers once the app was monetized; the entry Basic plan is $14.99 with all features, with merchants upgrading to higher tiers as the app drives them more revenue.
