📈 The Growth Story

Agent Companies as % of YC Batch — With Projection to 2028

The trajectory is clear: In Winter 2024, 35% of YC companies were agent-related. By Spring 2026, it hit 55%. The latest batches show 67%. At this rate, 80%+ of YC companies will be agent-related by 2028. Every service will be delivered by agents.

📊 Overall Landscape (1,632 companies)

Three-Way Split

Composition by Batch

🔮 What This Means

The data shows a clear trajectory: AI agents are becoming the default way services are delivered.

In 2024, 1 in 3 YC companies were building agents. By 2026, it's 2 in 3.

The CaaS (Custom Agents as a Service) infrastructure layer is growing fastest — from 30% to 50% of agent companies in the latest batches.

This suggests the market is maturing: first come the agents, then comes the infrastructure to build and manage them at scale. We're now in the "picks and shovels" phase of the agent gold rush.
