RevenueCat is a developer tool for managing app subscriptions and in-app purchases.
More than 6K apps use the software, processing more than $1B per year.
And the startup raised a $40M Series B from the Y Combinator Continuity Fund in May.
RevenueCat is part of the app monetization tools meta trend.
Last year, the number of total app downloads increased by 6.9B.
Over the same period, the percentage of paid apps actually fell: from 4% to 3.5%.
But up-front purchases are only a small part of how apps bring in income. 56% of app developers make money through a subscription model, while 47% generate revenue from ads.
Tech that supports these models is in demand. Wappier is an AI-based tool designed to maximize mobile app revenue. And has raised $4M in seed funding.
Other fast-growing startups in the app monetization space include Smartlook (analytics), Braze (customer engagement), and Appy Pie (no-code app builder).
