Codrin Arsene

Codrin Arsene is the CEO and co-founder of PerformanceX, a Chicago AI startup that monitors employee communications to tell CEOs exactly who is performing, who is coasting, and who is about to quit. He built PerformanceX after running Digital Authority Partners, a $6M marketing agency where he discovered his most trusted VP was silently destroying the team. After interviewing 24 employees who were all suffering in silence, he reduced turnover from 30% to 4% using the same approach PerformanceX now automates for every client.

Before founding his companies, Codrin led digital strategy at Sears Holding Corporation and Ricoh International, managed ShopSEARS (50,000 users, $30 to $40 billion processed), and worked with 20+ AI startups. He holds an MA in Marketing from the University of Chicago on full scholarship and currently oversees $8.4 million in monthly ad spend across 74 healthcare practices.
