About Daniel McCarthy
I help companies lead through crucible moments—those high-stakes periods when growth has stalled, strategy is unclear, or the business model must evolve. As a seasoned CEO and advisor, I’ve partnered with private equity firms and leadership teams to drive transformation across information services, data, SaaS, marketplaces, and other recurring revenue businesses.I’m currently CEO of Atheneum, leading the transformation of a global expert-insights and information services platform, while continuing my work through Gallarus Advisors, where I partner with private equity firms and leadership teams on value creation, operating cadence, and strategic clarity.Across three decades as a CEO, operator, and advisor, I’ve led platform transformations, integrated acquisitions, rebuilt go-to-market engines, and scaled recurring-revenue businesses across data, information services, marketplaces, and SaaS. My work consistently sits at the intersection of business data, operating discipline, and human performance.Through Gallarus, I’ve also developed The Authentic Growth Project (TAGP) — a structured, self-guided reflection and decision framework designed to help leaders and individuals operate with greater clarity, alignment, and intention during periods of change. TAGP is built as a method, not a personality-driven practice, and reflects the same discipline I bring to operating and advisory work.
