Technology that brings people together.
Shadow Particle is a small, independent studio in Stockholm. We build social products with care, polish and a little playfulness, starting with HeyU.
Small studio, big standards.
Founded in Stockholm in 2018, Shadow Particle started with one belief: software should help people feel more connected, not less. That belief became HeyU.
As an independent studio we get to move carefully and keep a high bar, from the first pixel to the last edge case. HeyU 3.0 is a complete rebuild of everything we learned, designed to scale and to feel effortless.
Software should help people feel more connected, not less.
Innovation
We turn hard problems into experiences that feel simple and inviting.
Playful
The best products spark a little joy. We never forget that.
Craft
Details matter. We hold a high bar from the first pixel to the last edge case.
Impact
We build things that brighten people's everyday, not just their screen time.
