Bloom

What it is

Bloom is an agentic app builder that generates fully native mobile apps from a text or voice prompt. Each app includes authentication, a real-time Convex backend, and instant sharing via App Clips — no App Store required.

Who it's for

Non-technical founders who want to build and test mobile products without hiring engineers, and technical founders who want to prototype new ideas in minutes instead of months.

Why it's better

• •Goes from prompt to native iOS, Android, and web app in minutes — two words generated a working caffeine tracker with a 7-day chart and FDA data.
• •App Clip sharing lets anyone open your app from a single link, no App Store download, no TestFlight, no invite code.
• •Real-time sync between devices works out of the box in a single prompt — something extremely difficult to implement elsewhere.
• •Two-way GitHub sync on the pro plan: build in Bloom, edit in Cursor or Claude Code, and pull changes back in.
• •Full code access and full data portability — you own your source code and your database at all times.
• •Raised $3.5 million before YC Demo Day. Investors called it the best tech demo they had ever seen.
