Custom web apps engineered to scale.
Multi-tenant SaaS, internal tools, marketplaces, and dashboards — built on a stack we'd ship our own product on.
We've shipped dozens of production web apps. The stack is opinionated because we've seen what breaks at scale and what doesn't. TanStack Start, Postgres, Stripe, and the operational glue that makes a product actually usable from day one — auth, billing, audit logs, admin tools.

Architecture
Modern frameworks
TanStack Start by default — Next.js or Remix when the product calls for it. TypeScript end-to-end. No legacy stack lock-in.
Multi-tenant data
Postgres with row-level security, tenant isolation, and migrations you can actually run without downtime.
Auth + billing built in
Clerk, Auth0, or Supabase Auth wired with Stripe billing — seat-based, usage-based, or hybrid metering.
Performance budgets
Green Core Web Vitals, edge-rendered where it helps, and a real observability stack from day one.
CI/CD + preview envs
Every PR gets a deploy. Every release has a rollback. Engineering velocity stays high after launch.
Admin & internal tools
Custom admin consoles built alongside the product so your team can run pilots without engineering tickets.
Discovery
1-week scoping sprint. We pin scope, success metrics, and the smallest billable wedge.
Design
End-to-end flows in Figma. Designer and engineer paired daily — no design we can't ship.
Build
Weekly releases. Demos every Friday. Production behind feature flags from week one.
Launch & Handoff
Soft launch, performance tuning, and a handoff doc your future hires can ship on day one.
Every engagement ships these.
No upsell games. The full system is in the base scope so you can measure honest ROI from month one.

- Observability (logs, traces, metrics)
- Handoff documentation + onboarding loom
How long does an MVP take?
6–10 weeks is typical. We scope to the smallest billable surface first, then expand once design partners are using it.
What's your stack?
Default: TanStack Start, Postgres on Supabase, Stripe, Cloudflare for edge hosting, and OpenAI for AI features. We flex (Next.js, Remix, Neon, Clerk, Vercel) when the product needs something different.
Will I own everything?
Yes — code, design files, infrastructure access. From day one. No lock-in.
Do you stay on after launch?
Optional. Most clients keep us on a fractional retainer for 90 days, then hire in-house. Some keep us on indefinitely.
Ship in 6–10 weeks. If we don't pay for ourselves, we work free.
