Messaging Apps Are the New App Store for AI Agents

Sacha Dumay argues on Substack that messaging apps—not app stores—are becoming the distribution platform for AI agents, and startups must adapt.

Key points:

The old order: Google Play and the App Store ruled for a decade+, with 8.93M apps and 3.5B weekly active users as of mid-2026—a mature, crowded market.
Three shifts happened at once:
Form factor: one chat box handles most use cases and accepts non-deterministic input with zero learning curve—why ChatGPT became the fastest-adopted product ever (1M users in 5 days, 100M in 60 days).
Voice: talking is 3–4x faster than typing, unlocking use cases previously too slow.

Takeaway: for agents, messaging apps are the new distribution entry point, not traditional app stores.
