Cyrus Hessabi, who is passionate about transformative technologies, joined the OpenOcean London office in early September as an Investment Associate.

With a background at Salesforce and DN Capital, he’s supported enterprise software founders across Europe and the U.S. As an aerospace engineer by training, Cyrus draws a comparison between building a transformational company and building an aircraft: it takes thousands of moving parts assembled correctly to take off. Cyrus also holds an MBA with Distinction from Harvard Business School and he’s supported early-stage founders at Harvard, Stanford and Wharton with first-check investments at the MBA Fund
