YC spring 2026 batch shows 4% of startups with native mobile app as main product

Only 4% of startups in Y Combinator's 2026 spring batch listed a native mobile app as their main product, down from 15% in 2013, according to Bloomberg's Parmy Olson. The shift reflects founders concentrating on AI and agent-based products rather than standalone mobile applications. The same report notes that new releases on Apple's App Store surged by roughly 80% earlier in the period, indicating app supply grew even as the share of YC companies centered on mobile apps fell. The figures describe the composition of one accelerator batch and a broader app-store release trend, not a measured decline in mobile usage or revenue.
