A Cloud for Small Software: founder validation breakdown

Original RFS by Pete Koomen. Source: Y Combinator Requests for Startups.

The RFS in plain English

YC is asking for infrastructure that lets people safely create, run, share, and maintain tiny purpose-built software with agents.

Why now

AI coding agents make it easy to generate custom tools, but deployment, auth, data, maintenance, and permissions are still too heavy for small one-off apps.

IdeaCheck angle

This is a strong founder-market fit idea if the product owns the whole lifecycle: prompt, build, host, update, and retire small software.

Founder trap to avoid

The category can become a generic app builder unless it focuses on the messy operational parts that teams actually fear.

A concrete idea to test

A hosted workspace where ops teams can generate tiny internal apps with built-in auth, data storage, audit logs, and automatic maintenance.
