Accordion

Accordion is a value creation consulting firm exclusively serving private equity sponsors and their portfolio companies across the CFO's office. Founded to sit at the intersection of PE sponsors and their portfolio CFOs, Accordion's 1,000-person team delivers financial consulting, data and analytics, AI implementation, and operational improvements across the full investment lifecycle. Their solution areas span foundational accounting and FP&A enhancement, CFO technology implementation, performance acceleration, data and analytics, exit planning, transaction support, and turnaround and restructuring. Accordion does not offer NetSuite-specific services; they work across multiple ERP platforms as part of broader finance transformation engagements, and in 2025 they acquired A5 to expand Salesforce capabilities. They are recognized for deep PE ecosystem relationships and an unchallengeable heritage working directly with finance teams.
