I partner closely with founders, institutional investors, and internal product teams to structure fundraising strategy, scale commercial workflows, and deliver high-trust advisory outcomes in complex financial environments.Prior to Diadem, I spent nearly a decade at Citi, most recently as a Vice President on the Citi Velocity Credit platform. There, I led enterprise client engagement across institutional asset managers, drove sustained adoption of electronic trading and analytics tools, and served as the commercial business owner for multiple global platform initiatives in partnership with product, design, and engineering teams.I specialize in consultative, enterprise selling; scaling platform-driven businesses; and translating market and customer insight into durable commercial and product execution.
