Nakachi will assume the new role as former CEO and Co-founder, Kirk Wylie, shifts his focus to the overall product vision and development of OpenGamma. Wylie will remain Executive Chairman of the Board and focus his efforts full time on continuing to make technology innovations for the industry-leading OpenGamma Platform together with his co-founders Elaine McLeod (OpenGamma's Chief Quantitative Officer) and Jim Moores (OpenGamma's Chief Technology Officer). Wylie will be joined on the Board of Directors by Nakachi, as well as industry veteran, Steve Gibson, Managing Director at Euclid Opportunities.

"Mas is the perfect candidate to serve as CEO of OpenGamma. During his time as COO, Mas quickly proved his ability to transform our commercial operations, while clearly showcasing his capabilities to run a successful risk technology business," said Wylie. "I could not think of a better candidate than Mas. I believe the two of us working together is the best way for OpenGamma to continue its mission of becoming the de-facto standard for risk and analytics software for capital markets."

"This move is part of the natural evolution of OpenGamma and is a very positive step toward the overall growth and expansion that Kirk envisioned at the outset," said Bruce Golden, Partner at Accel Partners and the first investor in OpenGamma. "With Kirk establishing a firm foundation during the company's first few years, Mas can now take the company to the next level, allowing Kirk to focus full time on product and technology innovation."

"I am extremely excited to take on this new role and spearhead the continued global expansion of OpenGamma," said Nakachi. "I have had the pleasure of working with a fantastic team here since joining as COO, and I look forward to building upon the innovative vision that the three founders had when they started the company in 2009."
