What Big4.com does

Big4.com (DBA "Big 4") is a privately held financial advisory and consulting firm headquartered in New York that exclusively serves AmLaw 200 law firms — the 200 highest-revenue law firms in the United States. The firm is led by CEO Mary Johnson, who brings 15 years of hands-on experience as a law-firm CFO across top-tier firms and holds a BA in Economics and an MBA from Duke University.

The company's offering is organized into five integrated service lines: Strategic Finance (planning, M&A advisory, long-term financial planning, lateral partner evaluation, and practice group strategy); Operational Finance (FP&A, treasury and debt management, financial systems implementation, peer benchmarking, and collection-cycle reduction); Pricing and Legal Project Management (fee optimization, LPM frameworks, implementation support, and team mentoring); Partner Compensation and Training (compensation framework design, training development and delivery, and partnership agreement evaluation); and Fractional CFO services (on-demand executive financial leadership). All engagements are delivered as bespoke consulting work; Big4.com does not operate a software platform, proprietary technology product, or AI-driven analytics layer.

The business model is professional services on a quote-based/engagement-by-engagement basis, sold directly to law firm leadership through a consultative enterprise field-sales motion. Pricing is not publicly disclosed. No customer logos, headcount data, revenue figures, funding history, or partnership ecosystem are disclosed in the available sources, and there is no evidence of institutional or venture capital backing. Marketing is concentrated on the firm's website (big4.com), which serves as its principal thought-leadership and lead-generation channel.
