Top SchoolMarcus Elwin is an AI Lead based in Stockholm with 11 years of cross-industry experience building practical ML and AI products that drive business value. He has progressed from quantitative roles at Nasdaq to founding data-science efforts at ICA and scaling ML systems at Tink, before architecting LLM-powered legal automation as Lead AI Engineer at Pocketlaw and now leading AI at Kustom.

He mentors teams, speaks at industry meet-ups, and is comfortable translating regulatory and production constraints into robust AI solutions. Trained in machine learning (M.Sc., KTH), he pairs strong academic foundations with a pragmatic, service- and sales-oriented mindset. An early adopter of agentic AI patterns, he focuses on deployable, auditable systems rather than research for research’s sake.
