What CTM CPAs & Business Advisors does

Withum Smith+Brown, PC, doing business as Withum, is a U.S.-based professional services firm organized as a Professional Corporation that delivers accounting, tax, and business advisory services to enterprise clients across sixteen specialized industry verticals. Service delivery is organized into six core practice areas — Assurance and Accounting, Business Advisory Services, Digital Workplace Solutions, Forensic and Valuation Services, Risk Advisory and Assurance, and Tax Services — supported by additional offerings in Wealth Management and Investment Banking. The firm is led by CEO and Managing Partner Pat Walsh, maintains offices nationwide across the United States, and operates as an independent member of HLB – The Global Advisory and Accounting Network, which extends its international reach to 150+ countries. Vertical coverage spans Construction, Dealership Services, Energy and Oilfield Services, Financial Services, Government Contractors, Healthcare, Industrial and Consumer Products, Labor Unions, Life Sciences, Multiemployer Benefit Plans, Not-For-Profit and Education, Private Equity, Professional Services, Real Estate, Technology and Emerging Growth, and Theatre and Entertainment.

Revenue is generated primarily through professional services engagements — recurring annual audits, tax compliance and planning, transaction advisory across the M&A lifecycle, risk and cybersecurity consulting, and outsourced accounting (OASyS) — under a quote-based, RFP-driven engagement model with no publicly disclosed pricing. Customer acquisition is consultative and relationship-led, executed through dedicated industry-practice teams, content marketing (resource library, podcasts, case studies, videos), and industry events such as the Healthcare Symposium and AI-focused roundtables. The firm's Digital Workplace Solutions practice represents its technology-oriented layer, built on Microsoft cloud infrastructure and encompassing AI consulting, business process automation, CRM/ERP planning, implementation and migration, data analytics, and Microsoft Viva-based employee experience services. No public revenue figures, funding rounds, or completed M&A transactions are disclosed; the most prominent recent organizational signal is the promotion of 18 new partners in 2026, indicating capacity expansion across U.S. offices.

The AI capability is positioned as an advisory and implementation service helping clients adopt AI tools — including generative AI — primarily within the Microsoft ecosystem, rather than as proprietary models, research, or patents. As a privately held PC with no external capital, the firm relies on organic partner growth, service-line extension (Investment Banking, Wealth Management), and ecosystem partnerships (Microsoft, HLB) to scale.
