What SDI International Corp does

SDI International Corp is a privately held, women-owned procurement and extended workforce solutions provider founded in 1992 by Carmen Castillo and headquartered in Boca Raton, Florida. The company serves Fortune 500 and large multinational clients across more than 70 countries, with delivery centers in 20+ countries and multilingual support in 20+ languages. SDI operates two main service divisions: Procurement Solutions (Master Vendor Programs for tail and tactical spend consolidation, Procurement Process Services covering sourcing, supplier enablement and contract lifecycle management, and Procurement Strategy & Advisory) and Extended Workforce Solutions (Managed Services Programs for contingent labor and SOW governance, Payroll Solutions via Employer of Record and Agent of Record, and Workforce Strategy & Advisory including VMS implementation).

The company's revenue model is dominated by managed services and professional services engagements priced on custom enterprise quotes rather than published rate cards. SDI monetizes through program management fees on Master Vendor/MSP contracts, payroll processing fees on EOR/AOR engagements, and project or retainer-based advisory work. Customer concentration skews toward Fortune 500 enterprises in regulated, complex spend categories—energy and utilities, pharmaceuticals, technology, and retail—with named programs delivering measurable outcomes such as 10% average annual tail-spend savings, 70% supplier-base reduction, and 60% faster contract execution in pharma engagements.

Technology underpins the service delivery through an AI-augmented procurement platform combining GenAI, predictive analytics, anomaly detection, and computer-vision document processing, integrated into client environments including Coupa. The company emphasizes women-owned business certifications (WEConnect International, WBE Canada, CAMSC) as a structural procurement advantage for Tier 1 diversity reporting. In October 2025, SDI announced a strategic merger with HCMWorks Inc., with Allison McCrea assuming the CEO role and founder Carmen Castillo transitioning to Strategic Advisor, creating an enlarged combined entity spanning North America, Latin America, Europe, and Asia.
