The round brings total funding to $47 million.

Founded in 2024, Larridin links AI adoption, productivity and spend data to the work of people and agents, showing leaders where AI delivers value. It has measured over 2 billion AI sessions and 82,000 workflows, reporting a 47% average increase in team output and a median $2.4 million in optimized AI spend within the first year.
