Shopify bundle and upsell apps monetize merchant demand through the app marketplace.
Kaching Bundles around $400K MRR · about 90% profitable
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
Erikas Malisauskas and a cofounder built a portfolio of Shopify apps after he discovered the app marketplace while working as a web designer for $2 an hour. The first product, Kaching Bundles, helps merchants increase average order value through discounts and bundles. The founders later added post-purchase upsell, pop-up upsell, and cart-drawer upsell apps. In the interview, Erikas says the portfolio had five apps, $4.5 million in annual recurring revenue, and about 90% profitability. He says Kaching Bundles alone was around $400,000 in monthly recurring revenue. The apps launched starting in August 2022, and the founders claimed their products had contributed more than $400 million in additional merchant revenue; that is their own attribution, not an independently measured result. Their distribution relies on the Shopify app ecosystem rather than paid advertising. Reviews and customer support help app listings rank for relevant searches. The case is a portfolio-scale reference: platform demand, tight product focus, and fast support can combine into meaningful recurring revenue.
