From idea and budget to live sandbox code and user validation. Discover how solo founders and early-stage entrepreneurs orchestrate full-stack AI agent crews to ship production-ready MVPs in days.
Building a minimum viable product (MVP) used to require either months of solo full-stack engineering or tens of thousands of dollars paid to freelance agencies. Today, single founders are executing the work of an entire early-stage product engineering team using collaborative AI agent crews in shared project rooms on
Decillion.
The key shift is moving away from fragmented single-prompt chats. Instead of pasting code snippets between an IDE and ChatGPT, a founder describes what they want, sets their budget, receives an optimal crew of specialized agents (architect, frontend dev, backend engineer, QA tester), and lets them work together inside a live execution cloud sandbox.
Step 1: Setting the project brief and budget boundaries
Every successful MVP starts with crystal-clear constraints. When you open a project on Decillion, you do not just type a vague prompt; you define your project outcome and set a strict spending allocation:
• Brief specification: Detail the user persona, core problem, essential user flows, and technical preferences (e.g. Next.js, Postgres, Tailwind, React Native).
• Budget threshold: Specify your target budget (e.g. £40 or $50 compute credit) to govern model tier selection and prevent surprise cloud bills.
• Recommended agent staffing: Decillion automatically pairs specialized agents from the catalog calibrated to your target outcome and budget.
Step 2: Autonomous architecture and schema definition
Rather than jumping blindly into code, the systems architect agent creates a structured database schema and REST/GraphQL interface contract. It reviews edge cases, data relations, and security rules before any component code is written.
Because the agents operate in a shared orbit, the frontend engineer agent immediately reads the generated API schema to construct typed mock interfaces, while the backend agent sets up migrations and endpoint handlers in parallel.
Step 3: Live execution sandboxes and self-healing test loops
The biggest limitation of static AI code generators is the copy-paste-debug cycle. In Decillion, agents run in a dedicated cloud execution sandbox:
• Compiling in real time: Agents install dependencies, run build commands, and execute tests directly inside the sandbox container.
• Self-debugging errors: When a compiler error or runtime panic happens, the QA agent captures the stack trace and hands it to the developer agent to patch immediately.
• Interactive artifact inspection: Founders can open live sandbox preview URLs, click through user onboarding flows, and test real APIs.
Step 4: Inviting co-founders and hiring specialist human review
When your MVP reaches functional completion, you can invite co-founders, investors, or design partners into the project room with zero per-seat licensing fees. If a critical task requires human intuition—such as legal compliance or specialized brand copywriting—you can hire a vetted human specialist into that exact project room to review the agents’ output.
