What SEI does
SEI (legal name Systems Evolution, Inc.) is an employee-owned U.S. management consulting firm founded in 1992 in Cincinnati, Ohio, by Dan Pierce, with current CEO Bill Gallagher in seat since 2014. The firm operates a nationally connected, locally committed network of 14 offices across major U.S. metropolitan markets and employs between 501 and 1,000 people, including senior consultants averaging roughly 18 years of industry experience. SEI delivers professional services — not a software product — across five capability areas: AI & Technology (agile transformation, application development, cloud strategy, DevOps, solution design), Concept to Delivery (change management, design thinking, product management, rapid prototyping, solution delivery), Data & Analytics (advanced analytics, governance, modernization, strategy, visualization), Security, Risk & Compliance (compliance, data privacy, information security, risk management), and Strategy & Operations (M&A, operational transformation, organizational design, process improvement, strategy and execution).
SEI's go-to-market is sales-led and direct, targeting Fortune 1000 enterprise accounts and mid-market organizations through locally staffed offices and senior practitioner-led engagements. Revenue is generated through project-based and multi-year advisory consulting engagements with quote-based pricing; no standardized pricing is publicly disclosed. The firm has completed 230+ AI projects in the past two years and holds a FedRAMP 20x Class C Certification, with a proprietary four-phase AI Transformation methodology underpinning the AI practice. SEI divested its family offices services unit to Aquiline in July 2025 and participated as a strategic investor in Avantos's $25 million Series A in February 2026, indicating both portfolio rationalization and selective ecosystem capital deployment. The firm maintains implementation partnerships with Microsoft, AWS, Snowflake, ServiceNow, Workday, and other major enterprise platforms, and has been recognized as the nation's #1 Best Consulting Firm to Work For by Consulting Magazine in 2023 and 2024.
