I’m Hans Kristoffer, a product and technology consultant who turns good ideas into products people use.
Founder, investor and full-stack developer. I scope it, build it and ship it.

2025-2026Investor & MVP developerInvested capital and work, and built the first version of the product.
Bookli
2019-2023Founder · ExitedPadel booking platform I built alone: booking, memberships, payments, admin and light/door control. 200+ courts and 130,000 users at the sale after 2½ years.
I thrive where good ideas need to become products. I connect business, product and technology, and build it myself, from the first decisions until the solution is live.
My experience comes from my own companies, where both capital and work were on the line. I built the padel booking system Bookli alone, and at the sale it ran 200+ courts and 130,000 users. Since then I’ve invested in Geysier, Barma and Snowii, taking their products from first version to thousands of users.
As a consultant I help scope the first version, get it in front of customers fast, and lay a technical foundation a team can keep building on. Based in Aarhus, open to Copenhagen, working in Danish and English.
