Web & product apps
Full-stack web applications built to be fast, maintainable, and easy to grow with your business.
Boutique software engineering
We build software worth relying on.
MarkOne is a small, senior team that designs, builds, and ships web and product software for founders and growing teams. No bloat, no hand-offs — just work that lasts.
What we do
APIs & backends
Reliable APIs, integrations, and data pipelines — the plumbing your product depends on, done right.
AI onboarding & consultancy
Bring AI into your product and your team the right way — from practical strategy and tool selection to building LLM features and getting your people productive with them.
Consulting & reviews
Architecture guidance, code reviews, and a second pair of senior eyes when you need to move with confidence.
A small team by design
We keep MarkOne deliberately small so the people you talk to are the people who write your code. That means clear communication, honest timelines, and software we're proud to put our name on.
