Brock Arnason

Brock Arnason is the founder and CEO of Droit, a New York regtech firm that turns the live text of financial regulation into auditable, machine-readable logic - a discipline it calls computational law. A Cornell-trained engineering physicist and former Morgan Stanley fixed-income e-commerce executive, he started Droit in 2012 to solve the Dodd-Frank derivatives mess from the inside. Droit's Adept platform now answers 'can I trade this?' and reports trades for clients including Goldman Sachs, Wells Fargo and UBS, and in 2025 the company was acquired by capital-markets technology giant FIS.
