We build software,
to the summit.
PeakStack is a software studio. We design and ship fast, reliable web and mobile products — from first line to production — with the polish of a senior team and the pace of a startup.
web · mobile · APIs — one senior team, end to end
From idea to a product in the world.
One team that designs, builds, and ships — so nothing gets lost in a handoff between agencies.
Web applications
Fast, accessible web apps and dashboards built on modern React, Next.js, and TypeScript — the same stack that powers this site.
Mobile apps
Cross-platform iOS and Android apps with React Native and Expo — one codebase, native feel, shipped to both stores.
APIs & backends
Typed APIs, auth, payments, and data models designed to scale — with the boring reliability your product depends on.
MVP to launch
Have an idea? We take it from wireframe to a launched, real product — and stay on to iterate once users arrive.
Modern tools, boring reliability.
We build on a proven, type-safe stack — the same one behind products handling real payments and real users.

A clear climb, every time.
No mystery, no month-long silences. You see progress every week and always know the next milestone.
- 01
Scope & shape
We turn your idea into a concrete plan — flows, screens, and a milestone-based roadmap with a fixed first deliverable.
- 02
Design & build
You see working software every week, not slides. Tight feedback loops keep the product exactly on course.
- 03
Ship to production
We launch on infrastructure you own — app stores, your domain, your accounts — with monitoring wired in from day one.
- 04
Iterate & support
Real products are never done. We stay on to improve, fix, and grow the product as your users tell you what's next.
The team you'd hire if you could.
Senior product engineering, without the cost and lead time of building an in-house team.
Startup pace, senior quality.
You get weekly shipped software from people who've built and secured real products — not a junior team learning on your budget.
Security is built in.
We come from an offensive-security background, so auth, access control, and data handling are done right from the first commit.
One stack, end to end.
Web, mobile, and backend from a single team that owns the whole picture — no handoffs, no finger-pointing.
You own everything.
Your code, your repos, your cloud accounts, your app-store listings. No lock-in, no hostage code.
Fixed scope, fixed price, clear milestones.
Every engagement starts with a defined first deliverable at a fixed price — so you know exactly what you're getting before we write a line. No open-ended hourly surprises.
Tell us what you want to build.
Send a few lines about your idea or project. We'll reply with honest next steps — and a fixed-price first milestone if it's a fit. No hard sell.
