About us.
A small, independent studio for rental and resale businesses on TWICE Commerce — run by someone on the TWICE Commerce team. One person does the work, with a few trusted helpers for the parts that need them.
Founder
Karri Hiekkanen.
Founder · Growth Lead at TWICE Commerce
GROU.Studio came out of four years on the TWICE Commerce team — answering the same setup questions and building the same things for rental and resale businesses, again and again. This makes that available to book.
Karri still works at TWICE Commerce and runs the studio from Helsinki on the side. The help comes straight from someone inside the platform — not an outside agency that has to guess.
Principles
How we work.
Four things we always stick to. They've helped us avoid small problems becoming big ones, and they guide which jobs we take and which we don't.
We know TWICE Commerce from the inside.
Four years on the TWICE Commerce team means we know how it actually works — the useful bits most people miss, the shortcuts, and where it's going. Less time guessing, fewer dead ends.
We do the work ourselves.
The person you hire does the work — no passing it to someone more junior, nothing handed off to someone else. If we can't do it properly ourselves, we say no.
We keep it small.
We keep the number of active clients small, so each one gets proper attention — not just a place in the queue.
Short jobs with a clear price.
We keep jobs to a week or two, with a clear price before we start and something working at the end.
By the numbers
Four years inside.
These are Karri's numbers from working at TWICE Commerce — not the studio's. But they're why the studio exists.
