We build
products that
reach orbit.
Jupiter Technologies is an independent software studio. We build and ship our own products — from exam prep games to AI-powered financial tools.
A studio that builds and ships
Jupiter Technologies is a Swedish independent software studio. We identify real problems, build focused products around them, and put them into the world — no clients, no agencies, just software we believe in.
From education to finance to productivity, we look for problems worth solving and build the tools to solve them.
Products, not projects
We don't take client work. Every line of code we write is in service of a product we own, believe in, and intend to grow.
Ship, then improve
We favour getting something real into users' hands over perfecting in private. Feedback from real usage beats speculation every time.
Built to last
We build with quality stacks and clean architecture. Products we can maintain, extend, and be proud of years from now.
What we're building
We identify real problems, build focused products, and ship them to the world. No clients — just products we believe in.

A game-based platform for studying and practising the Swedish university admission test. Learn through interactive exercises, real exam simulations, and instant feedback.

Asterisk Strategies
An investment strategy platform
A tool for building, testing, and refining investment strategies. Asterisk Strategies combines data-driven insights with a clean interface for serious investors.
SAT Game
Study for the American SAT exam
Bringing the HPSpelet formula to the US market. A game-based study platform for the SAT — interactive, adaptive, and built to get results.
From idea to orbit
A disciplined approach to building products people actually want to use.
Identify
We look for real problems in underserved markets. Every product starts with a simple question: what does the world actually need, and why hasn't it been built well yet?
Validate
Before writing a line of code, we validate the concept. User research, competitive analysis, and rapid prototyping — we make sure we're solving the right problem.
Build
Focused sprints, clean architecture, and continuous testing. We build for performance and longevity — products that hold up as they scale.
Launch & Grow
Ship fast, gather data, iterate relentlessly. Our products keep improving after launch. We're in it for the long run, not a one-time release.
Battle-tested tools
We build with technologies that are proven, scalable, and built for the long run.
