From idea to launch in 30 days

When FinanceFlow approached us with their idea for a B2B payment automation platform, they had a tight deadline: launch before their biggest competitor's annual conference in 30 days.

Here's the exact process we followed to take them from concept to live product in record time.

Week 1: Foundation & Core Features

We started with a 2-hour discovery call to understand their vision, target users, and must-have features. Within 24 hours, we had:

  • Set up the tech stack (Next.js, Supabase, Stripe)
  • Created the authentication system
  • Built the dashboard shell
  • Designed the core payment flow

By day 5, users could sign up, log in, and see their dashboard. Nothing fancy, but it worked.

Week 2: Payment Integration & Business Logic

This is where things got intense. We focused exclusively on the payment automation engine—the core value proposition of the product.

Key deliverables:

  • Stripe Connect integration
  • Automated invoice generation
  • Payment scheduling system
  • Email notifications
  • Basic reporting

We deployed to production daily, allowing the founder to test with real data and provide feedback immediately.

Week 3: Polish & User Experience

With the core functionality working, we focused on making the product feel premium:

  • Refined the UI with smooth animations
  • Added loading states and error handling
  • Implemented responsive design
  • Created onboarding flows
  • Added helpful tooltips and documentation

Week 4: Testing & Launch Prep

The final week focused on reliability and marketing:

  • Conducted thorough testing across devices
  • Fixed edge cases and bugs
  • Set up analytics and monitoring
  • Created landing page and marketing materials
  • Prepared launch sequence

Launch Day Results

On day 30, FinanceFlow launched at the conference. The results exceeded expectations:

  • 127 signups in the first week
  • 23 paying customers by week 2
  • $12,000 MRR within 30 days of launch
  • Featured in TechCrunch

Key Lessons

What made this 30-day sprint successful:

  1. Clear priorities: We focused ruthlessly on core features only
  2. Daily deploys: Continuous feedback prevented wrong turns
  3. Modern stack: Using proven tools accelerated development
  4. Single decision maker: The founder could approve changes instantly

This approach won't work for every product, but for MVPs and early-stage products, it's incredibly effective.

This is exactly what we need! Our agency quoted us 6 months. How do you manage to move so fast without sacrificing quality?

Impressive speed. What tech stack did you use for the payment automation? We're building something similar.

The daily deploy strategy is brilliant. We've been stuck in 2-week sprint cycles and missing opportunities.
