Guardinex
This startup from Aravind Immaneni WG06 is enlisting machine-learning models in the fight against identity fraud. Fresh off $5 million in funding last year, Guardinex has attracted attention for its patented technology that crunches data and continually learns new tactics to protect businesses and their customers from threats. Formerly global head of operations and fraud prevention at Citi, Immaneni laid the foundations for Guardinex in 2018 and officially got the company off the ground two years later.
