Summary
Headcount expansion differed meaningfully between the two firms. Apollo expanded its London workforce by 39 positions to 340 total employees, but this growth came exclusively from administrative staff additions, with investment professional roles actually declining. Conversely, KKR grew from 169 to 182 employees, with expansion concentrated in executives and associates while administrative headcount contracted. These hiring patterns suggest divergent operational strategies: Apollo appears to be scaling operational infrastructure while potentially optimizing professional staffing levels, whereas KKR prioritizes revenue-generating talent.
Compensation metrics reveal the complexities of comparing the two organizations. Apollo's average per-employee pay rose 18% to $618,000 in 2025 from $521,000 in 2024, while KKR's increased 15% to £196,000 ($259,000) from £171,000 ($226,000). However, these figures obscure substantial structural differences. Apollo maintained 27 members (partners) while KKR reported 88 members—more than three times as many despite being smaller by revenue. This partnership density variation materially affects average compensation calculations, as partner compensation typically far exceeds professional staff compensation. The data suggests KKR's lower per-employee average reflects a broader partner base sharing profits, while Apollo's higher figure reflects a more concentrated partnership structure combined with the administrative hiring that dilutes the overall average less severely than at KKR.
Both firms have maintained hiring momentum and revenue growth despite recent industry headwinds affecting compensation packages broadly. The results demonstrate that leading private equity and private credit platforms continue to attract talent and scale operations in London, though their divergent approaches to organizational structure and staffing composition reflect distinct business models and market positioning strategies.
