Roenen Ben-Ami is the Co-Founder and Chief Risk Officer of Justt, the AI-native chargeback management platform named to the 2026 Forbes Fintech 50. Since co-founding the company in 2020, he has shaped Justt’s product and vision, building an AI-driven chargeback automation platform that enables merchants to fight and win disputes more effectively.

Justt has raised $100 million in funding and today serves over 250 global enterprise merchants and more than 50,000 SMBs, operating from offices in New York, London, and Tel Aviv, with the United States as its largest market. Because Justt was AI-native from day one, and built on the belief that the right technology must be combined with deep domain expertise and methodology, the company was positioned to deliver the most powerful enterprise-grade tailored chargeback solution designed to recover more funds for merchants than traditional approaches.

Roenen is widely recognized as an expert in chargeback mitigation, payments, and risk management, and is passionate about creating a fairer, more efficient dispute ecosystem.

Prior to founding Justt, he built and led the Chargeback and Merchant Risk teams at Simplex (acquired by Nuvei), where he developed strategies that recovered millions of dollars annually for merchants. A sought-after speaker, he regularly appears on stage at conferences like Money20/20, MRC and others, and contributes to leading payments podcasts and publications. Roenen holds a B.S. from the University of Illinois at Urbana-Champaign.
