Positioning

We build SaaS that ships, scales, and survives — not pretty mockups that die in a sprint review.

01 — Built to ship

Most agencies hand you a Figma file and a deck. We hand you a production app, in your repo, with the keys to scale it.

02 — Built to scale

Every product we ship is engineered for the day after launch — typed end-to-end, observable, and designed to support 10× the traffic without a rewrite.

03 — Built to survive

We don't disappear after week six. Retainers, audits, and on-call windows keep your SaaS healthy long after the launch tweet.

What we build

Four things, done obsessively well.

No retainers for the sake of it. No deliverables you can't ship. Pick one — we go deep.

01

Custom SaaS

Multi-tenant SaaS engineered end-to-end — auth, billing, dashboards, integrations, infra. We ship the v1 your investors expected.

Ideal for

Founders with a validated wedge and 12 months of runway.

  • Multi-tenant architecture
  • Stripe / Paddle billing
  • Admin + customer dashboards
  • Production deploy on day one
02

Custom Web Apps

Hand-crafted internal platforms, marketplaces, dashboards, portals — fast UI, typed APIs, real-time where it counts.

Ideal for

Operators replacing internal tools, spreadsheets, and Zapier glue.

  • Bespoke UI / UX system
  • Typed APIs (tRPC / REST)
  • Real-time + offline-ready
  • SSO + audit logging
03

Mobile Apps

Native-quality mobile apps on React Native and Expo — push, payments, offline sync, and in-app purchases. One codebase, two stores, one polished product.

Ideal for

Founders shipping iOS + Android from one codebase, without compromising on feel.

  • iOS + Android from one codebase
  • Push, deep links, biometrics
  • Offline-first sync
  • App Store + Play Store launch
04

Scale & Re-architect

Audits, re-architects, and engineering pods that turn legacy product debt into a platform you actually want to ship on.

Ideal for

Existing SaaS hitting the wall on perf, cost, or team velocity.

  • Architecture audit
  • DB & query optimisation
  • CI/CD + observability
  • Embedded engineering pod

How we work

From a Notion doc to a live product in six weeks.

One process. Four phases. Zero ceremony — every artifact ships.

01Week 0 — 1

Discover

We pressure-test your idea, map the wedge, and write a one-page product spec everyone can stand behind.

Artifacts

  • Product brief
  • Tech approach
  • Estimate & timeline
02Week 1 — 2

Design

Wireframes, then high-fidelity flows in days, not months. We design only what we'll ship.

Artifacts

  • Core flows
  • Design system v1
  • Clickable prototype
03Week 2 — 5

Ship

Daily builds, demo every Friday. Production deploy on day one — your real users live in it long before launch.

Artifacts

  • Daily deploys
  • Weekly demo
  • Production-ready stack
04Week 5 — ∞

Scale

We stay on as your product partner — features, perf, infra, hires — until you don't need us.

Artifacts

  • Roadmap
  • On-call
  • Engineering pod

Selected work

Products people actually pay for.

14 shipped builds across SaaS, mobile, and AI — every one production-grade, most still live today.

Founders, not flowers

Words from the people who wired the bank transfer.

Real outcomes. Real signatures. Tap a name to read the next one.

Zak was an outstanding developer to work with. He delivered work remarkably fast without ever sacrificing quality. He consistently beat expectations on turnaround time, and communication was seamless throughout. What impressed me most was his ability to make smart design decisions independently while still thinking things through thoroughly. He made an effort to understand the product and implement the web solution in a faithful manner. He struck the perfect balance between moving quickly and being deliberate. I'd highly recommend Zak and would absolutely work with him again.

Need to automate the work, not build the product?

Statelift ships SaaS, web and mobile apps. Our sister studio Operwave replaces the manual work behind them — turning repetitive ops, lead capture, billing and reporting into AI-powered workflows that run on their own.
