About Galaxen
The studio founders keep recommending.
We started Galaxen in 2019 with a simple thesis: most founders waste their first six months building the wrong thing in the wrong way. We fix that.
Galaxen was founded by Daniel Hartley and Sofia Andersen after watching dozens of talented founders lose critical runway to agencies that over-promised, under-scoped, and disappeared after handover. Daniel had lived it himself — spending $120K on an MVP that took 9 months and never found a single paying customer. Sofia had seen it from the engineering side, inheriting three separate codebases at her next role that were essentially throwaway.
The studio was built around a conviction: the best thing you can do for a founder is tell them the truth. That means being honest when an idea won't work, honest when the timeline is tight, and honest when scope needs to be cut. We're not here to take your money — we're here to get you to product- market fit as fast as the idea allows.
Six years later, we've shipped over 60 products, worked with founders across 12 countries, and helped our clients collectively raise more than $180M. We're still a focused studio — deliberately. We don't scale for scale's sake. Every active project has a named lead, a direct Slack line to the build team, and a founding partner who's read the brief.
If you want an agency that treats your product like a contract deliverable, we're not the right fit. If you want a team that argues with you when you're wrong, ships fast, and picks up the phone on launch day — let's talk.

What we believe
Four principles we don't negotiate on.
Say the hard thing
We tell clients when an idea won't work, even if it costs us the project. Our job is to get you to product-market fit, not to take your money.
Ship to learn
A live product with 50 real users teaches you more in a week than 3 months of spec documents. We build to ship, not to polish indefinitely.
Own the outcome
We measure ourselves by the results our clients achieve — funding rounds, user growth, revenue — not by deliverables handed over.
Code you'd be proud to inherit
Every codebase we hand over is documented, tested, and structured so your next developer can hit the ground running.
Leadership
Built by people who have shipped.
