Key Result
Live with paying customers in 6 weeks
The Challenge
A non-technical founder had an idea for a B2B payment reconciliation tool but needed to validate it with real customers before raising a seed round. They needed an MVP that looked professional, worked reliably, and could handle real transactions - but didn't need every feature pla
ed for the full product.
Our Solution
We delivered a lean, focused MVP that:
Allows businesses to upload bank statements and invoicesnAutomatically matches transactions using smart algorithmsnFlags discrepancies for reviewn Includes basic user authentication and role-based accessnIntegrates with Stripe for billing pilot customers
Built with Next.js, PostgreSQL, Stripe, and Plaid for bank co
ections. Clean UI that looks like a mature product despite being v1.
Technologies Used
The Results
Shipped in 6 weeks from kickoff to production:
3 paying pilot customers in first monthnUsed to process $50K+ in reconciliations in first 2 months
Founder used the working product + early traction to secure $800K seed round
MVP is still in production serving customers while v2 is being built by their new in-house team.
"SJK helped me go from idea to paying customers in 6 weeks. The MVP they built was crucial in raising our seed round. Clean code, solid architecture, and most importantly - it worked."
