Founders

People behind the Stockholm challenge studio

Linnea Forsmark

Linnea leads participant experience and keeps every cycle clear, realistic, and easy to follow from the first week.

Jonas Halder

Jonas develops digital workflow structure so participants can track routines with low friction and clear visual feedback.

Shared vision

The team prioritizes balanced routines, transparent communication, and informed user choice.

Our operating principles

We design challenge journeys that are understandable, measurable, and moderate in intensity. Product decisions are tested against clarity, inclusiveness, and legal transparency.

Founder commitments

No unrealistic promises

We communicate process and structure, not guaranteed personal outcomes.

User rights first

Data handling, consent options, and support contacts stay visible and accessible.
