Founders Are Retaking the CEO Chair at B2B Incumbents Losing to AI-Native Competitors

Jason Lemkin has been tracking a pattern: founders retaking the CEO seat at established B2B SaaS companies large enough to survive but growing too slowly to stay competitive against AI-native entrants. Daniel Dines returned to UiPath after four months under Rob Enslin, following a growth slowdown from 21% to 12% ARR and cut guidance — under Dines, the company has since posted four consecutive quarters of GAAP operating profit while holding 109% net revenue retention. Aneel Bhusri resumed leadership at Workday in February 2026 after Carl Eschenbach’s two-year tenure, with the company guiding to just 11% growth despite $10 billion in revenue, prompting take-private interest from investors. Eoghan McCabe returned to Intercom, renamed the company “Fin” after its AI agent product, and executed a roughly $3.6 billion acquisition by Salesforce.

Lemkin’s argument is that hired CEOs generally can’t execute the pivots these moments demand — cannibalizing existing pricing models, accepting margin compression — because they lack the voting control to force through decisions the board or the team will resist. Founders with that control are willing to make the trade. He’s careful to note reacceleration has remained elusive even for the founders profiled; coming back doesn’t guarantee the turnaround works.

Forrester’s own market-disruption framework, published three weeks earlier, sorts markets into Disrupted, Neutral, Contested, and Accelerated categories and states plainly: “AI’s effects will not be distributed evenly. While some markets and vendors face extreme headwinds, others are poised for historic acceleration.” UiPath’s RPA category and Workday’s HR-suite model both sit closer to Contested-to-Disrupted territory in that framework — automation and AI agents compress the value their core products used to deliver standalone. The founder-return wave Lemkin is describing is what that disruption model looks like from inside a boardroom, one earnings call at a time.
