What NDH Group does
NDH Group, operating commercially as Prosperity Partners and Prosperity Partners CPA, is a US professional services firm providing accounting, tax, and advisory solutions to mid-market and enterprise businesses as well as high-net-worth individuals and families. The firm operates through two legal entities — NDH Advisors LLC (tax, accounting, advisory) and NDH CPA LLP (attest services including audits and reviews) — and delivers a full-service portfolio comprising Client Accounting Services, Tax Services, Family Office Services, Assurance, Transaction Advisory Services (with sub-modules for Sell-Side and Buy-Side Quality of Earnings, M&A Readiness, and M&A Integration), and Special Projects. The Transaction Advisory practice is the most strategically emphasized line, targeting M&A due diligence and integration work.
Since a May 2023 platform investment from Unity Partners LP, NDH has pursued a PE-backed roll-up strategy, completing two acquisitions within roughly twelve months (Jain & Jain in Houston in January 2024 and McGowan Guntermann in Santa Barbara in June 2024) and expanding to ten offices across major US metros including Chicago, New York, Houston, Santa Barbara, Detroit, Kansas City, the Washington DC area, Burlington, and Iselin. The firm pairs this acquisition cadence with an employee ownership program under which acquired-firm employees receive equity, intended to retain talent and align incentives across the platform.
The revenue model is professional services billing — recurring client engagements plus project-based fees for Transaction Advisory and Special Projects — with pricing not publicly disclosed and contracts negotiated by engagement scope. Go-to-market is enterprise field sales via direct client engagement. No core technology or AI capability is disclosed in the available sources, despite the firm's stated innovation values. Externally, NDH was named to Accounting Today's Top 100 Accounting Firms of 2026 and ranked #3 on the Fastest Growing Firms list, with CEO Jeremy Dubow recognized as a Forbes 2026 Best-in-State Top CPA, providing third-party validation of the growth trajectory.
