Under his stewardship, the company has grown from modest beginnings to a thriving enterprise employing 30 staff members and serving 25 clients, the majority of whom are acquired through referrals.

Mr. Santiago's vision for S4 Market Data was shaped by his observation that many financial institutions approached market data spending tactically, lacking the specialized expertise required for optimal results.

In addition to his executive responsibilities at S4 Market Data, Mr. Santiago has contributed his expertise as an advisor to Tractiv from 2020 to 2025 and Korzo from 2022 to 2025.

Academically, Mr. Santiago's background includes a Master of Business Administration from Florida International University College of Business, completed in 2018 and a Bachelor of Business Administration in management information systems and services from Lubin School of Business at Pace University, earned in 1998. The technical foundation gained during his undergraduate studies proved instrumental when he first entered the field of vendor management and market data sourcing—a path he discovered while working as an undergraduate after being introduced to the profession by a friend.

Mr. Santiago's credentials are further distinguished by his attainment of the Lean Six Sigma Yellow Belt certification from GoLeanSixSigma.com in 2016. He is also an active member of industry-related organizations, such as the Financial Information Services Division.
