The Challenge

Processing $1M+ in daily transactions without a technical co-founder or in-house engineering team. The initial MVP was built by freelancers and couldn't handle the load. Payment reconciliation was manual. Customer onboarding took weeks. The founder needed a technical partner who could architect for scale while shipping features daily.

Our Solution

We partnered with AirBills as their strategic technology advisors—providing CTO-level guidance, architecture decisions, and delivery governance. Our strategic roadmap prioritized automated payment processing, real-time reconciliation, and self-serve onboarding. The architecture we designed handled 10x traffic growth without modification.

  • Automated payment reconciliation reducing manual work by 90%
  • Real-time webhook processing for instant payment notifications
  • Multi-tenant architecture supporting property managers of all sizes
  • Stripe Connect integration for seamless payment splitting
  • Automated compliance reporting for property management regulations
  • Self-service onboarding reducing activation time from weeks to minutes
