Case study
Overview
The brief
A production AI SaaS that turns natural-language conversations into complete, deployable Next.js applications. Multi-agent workflows generate, preview and iterate on real code inside secure cloud sandboxes.
The problem
Non-technical founders and product teams wanted to ship real web apps without hiring engineers. Existing no-code tools were too rigid; existing AI code tools felt like toys. Bloom needed to feel like a real engineering partner — safe, fast, and honest about what it was doing.
Our role
- End-to-end product architecture
- Multi-agent orchestration (planner, coder, reviewer)
- Live sandbox previews via E2B
- Credit-based usage engine + billing
- Auth, workspaces and file persistence

How we built it
Process.
01
Multi-agent design
Separate planner, coder and reviewer agents pass structured context so generations stay grounded and predictable — not a single opaque LLM call.
02
Secure cloud execution
Every generation runs inside an isolated E2B sandbox so users see a real running app, not a static preview.
03
One-click improvements
In-app edits go through the same agent chain, so a small change never breaks the rest of the app.
04
Credit-based economics
Usage is metered per generation with Clerk auth and Stripe billing, tuned so free users can meaningfully try the product.
