Overview
Unity Advisory provides non-audit CFO advisory services for upper mid-market, private equity-backed companies through three pillars: Finance, Deals & Value Capture, and Tax Matters. It operates with an AI-first delivery model that embeds artificial intelligence into core operations from day one to optimize processes, support deals, and manage tax affairs, while offering flexible, value-based fees. The firm differentiates itself by eschewing audit work, being privately backed, and led by former Big Four leaders, using a technology-native architecture to deliver concise, outcome-focused engagements. Its goal is to be a trusted, conflict-free CFO advisor that delivers measurable value in finance transformation, deal execution, and tax strategy.
