From having a handful of employees in 1997 to roughly 1,000 today, we have always been about creative collaboration, fostering diverse perspectives and being good corporate citizens. While we've always worked to exemplify these traits in how we do our jobs, terms like sustainability or ESG weren't really part of our corporate vocabulary for a long time. I invite you to follow our progress into the years ahead and the future we all share and look to shape." fectly LEE OLESKY Chief Executive Officer & Co-Founder, Tradeweb Markets Inc.
