Lenders Take Control of Medallia After Thoma Bravo Wipeout
Thoma Bravo is handing Medallia to a consortium of lenders — Blackstone, KKR, Apollo Global, and Antares Capital — via a debt-for-equity swap after its 2021 $6.4 billion acquisition. The transaction erases roughly $5.1 billion of equity from Thoma Bravo and its co-investors. Blackstone Secured Lending co‑CEO Brad Marshall said lenders plan to inject new capital, de‑lever the balance sheet, and that “Medallia is highly profitable today.” Core VoC capabilities (feedback collection, text analytics, journey mapping, contact-center intelligence) are expected to remain, but product “edges” and some recent AI feature bets face uncertainty until restructuring closes in the coming months. The episode highlights vendor risk for marketers buying from PE‑backed SaaS firms and prompts guidance on contractual protections, data portability, and product-roadmap commitments.
