The investment comes from WTSL, an investment firm led by Patrick Whitesell, the co-founder of talent agency WME and former executive chairman of its successor company, Endeavor. WTSL, which Whitesell launched in 2024 with backing from private equity firm Silver Lake, did not disclose the size of its investment in Unwell, though the deal establishes a $500 million pre-money valuation for the company, according to Unwell. Cooper and Kaplan, who self-funded Unwell since founding it in 2023, retain majority ownership of the business. Unwell said the company has been profitable since its founding and is treating the new capital as growth funding rather than a lifeline. The funding announcement lands just weeks after a pair of media investigations detailed allegations of workplace dysfunction at Unwell.
