Pedro Chiamulera

Pedro Chiamulera

Founder & CEO

Pedro founded ClearSale as a small start-up; it is now an international innovator in fully outsourced fraud prevention with more than 800 employees, operations in Brazil and the US, and global clients including Sony, Dell, and Chanel.

A two-time Olympic athlete, Pedro believes employee empowerment and creative problem solving yield the best results for clients. With ClearSale, Pedro changed CNP fraud management in Brazil. He also built a corporate culture of creative exploration, continuous learning, self-awareness, and fun to support employees’s personal and professional growth. The result is an employer of choice for top talent. ClearSale has ranked among Brazil’s Top IT and Telecom Places to Work for four consecutive years, and ranked among the country’s best workplaces overall in 2014.

Pedro earned his bachelor computer science degree from Point Loma Nazarene University in San Diego, California. After competing in the 1992 Summer Olympic and 1994 Winter Olympics in the 110-meter and 400-meter hurdles, he began his IT career.

Early on, Pedro developed the first e-commerce anti-fraud systems used by Submarino and C&A, two of the largest retailers in Brazil. Pedro founded ClearSale in 2001. By 2007, integrated manual order analysis allowed clients to outsource the entire risk management process. In 2010, ClearSale was Brazil’s second-fastest growing company. In 2011, New York’s Endeavor Global organization named Pedro a high-impact international entrepreneur.
