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:
- Clear priorities: We focused ruthlessly on core features only
- Daily deploys: Continuous feedback prevented wrong turns
- Modern stack: Using proven tools accelerated development
- 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.

Founder, StartupX·1 day agoThis is exactly what we need! Our agency quoted us 6 months. How do you manage to move so fast without sacrificing quality?

VP Engineering, TechCorp·2 days agoImpressive speed. What tech stack did you use for the payment automation? We're building something similar.

Product Lead, InnovateNow·4 days agoThe daily deploy strategy is brilliant. We've been stuck in 2-week sprint cycles and missing opportunities.
