Martin Källström

Twenty-five years of building tools for memory, expression and belonging — blog search with Twingly, a wearable camera for human memory with Narrative, same-day eyewear with Heywear, a creative operating system with Multiply, AI-native work at Elysium and Kindship, and now — as co-founder and CTO of Nūvai — the clinical platform and AI tools behind precision psychotherapy. This site is one life on the record: every claim traceable to the second it was said or the page it was printed on.
