Who is the ex CEO of Vertex?

Can you please tell me who the former Chief Executive Officer of Vertex was? I'm curious to learn more about the individual who previously led this company, especially in the realm of cryptocurrency and finance. It would be great if you could provide some context about their background and any notable achievements or accomplishments they had during their tenure at Vertex. Additionally, I'm also interested in knowing if there have been any updates or changes in leadership since their departure.
