What The Developmental Edge does
The Developmental Edge (TDE) is a privately held leadership development firm founded in 2013 in Atlanta, GA, that delivers methodology-anchored programs for senior leadership teams undergoing transformation. Its core offering is the Developmental Sprint, a 4-week peer-driven accelerator grounded in the Immunity to Change (ITC) framework developed at Harvard by co-founders Dr. Robert Kegan and Dr. Lisa Lahey. The product suite extends to the Super Sprint (one-week AI-intensified alumni accelerator with an AI Coach embedded in the TDE E-Tool), Developmental Workout (peer coaching applied to live business challenges), Team Sprint (collective transformation), and the 90-Day Senior Team Accelerator that integrates Sprint, Team Sprint, and Workout into a single multi-month engagement. Supporting offerings include Executive Coaching (ITC-based and Values-Based via the Hall-Tonna Values Inventory), No Fault Formula communication training, keynotes, and a Sprint Leader Training & Licensing channel.
TDE's go-to-market is enterprise field sales targeting CEOs, transformation leaders, CHROs, and senior leadership teams; supplemented by a community-led licensing channel that enables independent coaches and internal L&D functions to deliver the methodology, and a self-serve Public Sprint funnel. The firm operates globally, with documented delivery across 75+ countries in 11 languages and engagements for named clients including Google, General Mills, Cisco, US Navy, Uber, Novartis, EY, McKinsey, US Bank, Cirque du Soleil, Sweetgreen, and WellMed. Revenue derives from professional services fees on enterprise engagements, licensing and training fees, public cohort registration, executive coaching, and keynote fees; pricing is quote-based and not publicly disclosed. The firm is bootstrapped, founder-owned, and operates with 1–10 employees following the 2025 transition of co-founders Kegan and Lahey to emeritus roles, with Andy Fleming (CEO) and Claire Lee (Chief Business Officer) continuing as operating leaders.
