I Built a Bot That Builds SaaS Products: Introducing MicroSaaSBot
Announcing MicroSaaSBot—the AI system that takes ideas from validation to deployed MVP with minimal human intervention. It built StatementSync in one week.
I had a backlog of 47 SaaS ideas. Most would never get built.
The bottleneck wasn’t creativity—it was execution. Each idea requires:
- Market research
- Problem validation
- Architecture planning
- Actual coding
- Deployment
- Billing integration
Weeks of work before you know if anyone will pay.
So I built a system to do it for me.
Introducing MicroSaaSBot
MicroSaaSBot is an AI system that takes a problem statement and outputs a deployed SaaS product.
Input: “Bookkeepers spend 10+ hours weekly transcribing bank statements to spreadsheets.”
Output: StatementSync—a live product with user auth, PDF processing, and Stripe billing.
Time: One week.
This isn’t hypothetical. StatementSync is live. Users are paying. The AI built it.
The Four Agents
MicroSaaSBot uses specialized agents for each development phase:
Researcher Agent
- Market analysis
- Competitor research
- Problem scoring (0-100)
- Persona validation
Architect Agent
- Tech stack selection
- Database schema
- API design
- Security patterns
Developer Agent
- Feature implementation
- Test coverage
- Error handling
- Code quality
Deployer Agent
- Vercel deployment
- Database setup
- Stripe integration
- Environment config
Each agent is optimized for its phase. The Researcher agent knows nothing about coding. The Developer agent doesn’t care about market research. Specialization enables excellence.
The Workflow
Phase 1: Validation
You provide a problem statement:
“Bookkeepers spend 10+ hours weekly transcribing bank statements to spreadsheets.”
The Researcher agent investigates:
- Who has this problem? (Persona definition)
- How severe is it? (Pain scoring)
- Are they paying for solutions? (Willingness to pay)
- What solutions exist? (Competitive landscape)
Output: Problem score (0-100).
StatementSync scored 78/100:
- Severity: 8/10 (daily pain)
- Persona clarity: 9/10 (freelance bookkeepers)
- Willingness to pay: 8/10 (already paying competitors)
Green light.
Phase 2: Architecture
The Architect agent designs the system:
Frontend: Next.js 15 (App Router)
Auth: Clerk
Database: Supabase PostgreSQL
Storage: Supabase Storage
Payments: Stripe
PDF Processing: unpdf
Hosting: VercelKey decisions are surfaced for human approval:
- “Using pattern-based extraction (faster, cheaper) vs LLM extraction (more flexible). Recommend pattern-based for cost control. Approve?”
- “Flat-rate pricing vs per-file. Recommend flat-rate for user acquisition. Approve?”
You make the strategic calls. The agent handles implementation details.
Phase 3: Development
The Developer agent builds features:
- User authentication flow
- File upload handling
- PDF parsing engine
- Export generation (Excel, CSV)
- Billing integration
- Dashboard UI
Each feature includes:
- Implementation code
- Error handling
- TypeScript types
- Basic tests
Development happens in phases—each phase builds on the previous, with checkpoints for review.
Phase 4: Deployment
The Deployer agent ships:
- Vercel project configuration
- Supabase database setup
- Stripe product/price creation
- Webhook configuration
- Environment variables
- DNS and domain setup
Output: A live URL with working product.
What Humans Still Do
MicroSaaSBot handles the tedious 80%. Humans handle the meaningful 20%:
Strategic decisions:
- Approve/reject validation scores
- Choose between architectural options
- Set pricing and positioning
- Define brand/design preferences
Business operations:
- Marketing and sales
- Customer support
- Financial management
- Legal/compliance
Quality judgment:
- Review generated code
- Test edge cases
- Approve deployment
- Monitor production
Think of MicroSaaSBot as a senior engineer who executes your vision. You’re still the founder. You make the decisions that matter.
The First Success
StatementSync is proof this works:
| Phase | Duration | Output |
|---|---|---|
| Validation | 2 days | 78/100 score, approved |
| Architecture | 1 day | Tech stack, schema, approved |
| Development | 3 days | All features implemented |
| Deployment | 1 day | Live on Vercel with Stripe |
| Total | 7 days | Production SaaS |
The product converts PDFs to spreadsheets. Users pay $19/month. It works.
Why This Matters
The traditional path:
- Have idea (Day 1)
- Research market (Week 1-2)
- Plan architecture (Week 2-3)
- Build MVP (Week 4-8)
- Deploy and iterate (Week 9+)
- Maybe get users (Month 3+)
The MicroSaaSBot path:
- Have idea (Day 1)
- Validated + deployed (Day 7)
- Get users (Week 2)
Speed matters because:
- You learn faster
- You fail cheaper
- You iterate sooner
- You validate with real users, not assumptions
The Bigger Picture
MicroSaaSBot isn’t just a productivity tool. It’s a different way of building.
Traditional: Humans do everything, AI assists with code completion.
AI-first: AI handles the workflow, humans make strategic decisions.
The shift is from “AI helps me code” to “AI builds the product, I run the business.”
This is where product development is heading. MicroSaaSBot is my bet on that future.
What’s Next
The roadmap:
- More product types - Expand beyond web SaaS to APIs, browser extensions, automation tools
- Iteration system - Handle post-launch features and improvements
- Analytics integration - Let the Researcher agent learn from production data
- Template library - Pre-validated patterns for common product types
StatementSync was the first. It won’t be the last.
