What RBSM does
RBSM is a private, New York-based certified public accounting firm that delivers auditing, tax compliance, professional accounting, and assurance services. Founded in 2000, the firm operates with 101-250 employees, placing it in the mid-tier band of U.S. accounting practices by headcount. The firm's website (rbsmllp.com) signals a partnership-style structure (LLP), consistent with the typical legal and governance form for U.S. CPA practices carrying professional liability exposure.
The firm's product set is service-only and human-delivered: recurring audit and attest engagements, tax compliance and filings, and broader professional accounting and assurance work. No proprietary technology platform, software products, or AI/ML components are disclosed in the supplied data, and the technical layer underlying delivery (audit methodology, tax-preparation tooling, internal systems) is not described. There is no evidence of productized offerings, recurring software/SaaS revenue, or technology licensing.
The business model is a professional services fee structure — billable hours and engagement-based fees for audit, tax, and assurance work — targeting clients who require regulated CPA services. Customer segments, pricing details, channel mix, and GTM motion are not specified in the input, so go-to-market mechanics cannot be characterized. Corporate history beyond the 2000 founding year, management team, ownership structure, and operating geographies beyond the New York headquarters are likewise not documented in the supplied data.
