What we were handed

TechFlow had a strong founding-team idea — give digital agencies the project-management software they actually want, with workspaces, role-based access, real-time dashboards, and a public API for integrations. Two prior agencies had failed to ship it: one over-architected, one under-shipped. The founder came to us with a half-finished codebase and a hard pre-Series-A demo date 12 weeks away.

How we framed it

We did a one-week paid technical audit. The verdict: the existing code wasn't salvageable — multi-tenancy was wired through every layer in a way that couldn't be unwired without a rewrite. So we proposed a rewrite, fixed-price, 12 weeks, with weekly demos and a shared Slack. We'd ship the demo-able MVP by week 10, harden in week 11, and hit the demo date in week 12.

What we shipped

Laravel 11 backend with a clean multi-tenant abstraction (single database, scoped via middleware on every request). React + TypeScript frontend on Next.js. PostgreSQL with row-level security as a defense-in-depth measure. Stripe for billing with custom usage-metered entitlements. Public API generated via OpenAPI spec with auto-generated SDKs for the most-asked integrations (Slack, Linear, Figma). AWS infrastructure with auto-scaling, Sentry observability, and CI/CD via GitHub Actions deploying to production on every merge to main.

What happened

  • Hit the pre-Series-A demo on schedule. Founder closed Series A 6 weeks later.
  • Onboarded the first 50 paying customers within 90 days of launch.
  • Scaled to 8,200 active users across 340 paying workspaces by month 12.
  • 99.97% uptime over the first 12 months (one 8-minute incident, caught by alerts, fixed in 14 minutes).
  • Currently runs without dedicated ApexGenLabs engineering — handed off cleanly to their internal team.

The fastest agency we've ever worked with — and the only one that owned every layer from strategy to launch. We didn't lose a single sprint to handoffs, and the codebase they handed over was cleaner than anything our internal team would have produced.
