What Aderant does
Aderant is a global provider of cloud-based legal business management software, headquartered in Atlanta and operating as a wholly-owned business unit of Roper Technologies (Nasdaq: ROP). Founded in 1978, the company serves more than 2,500 law firm clients across 21 countries, including 97% of the Am Law 200 and 86% of the Global 100. Its platform addresses the full revenue cycle for law firms, spanning practice management, AI-powered timekeeping, outside counsel guideline compliance, bill delivery, pricing optimization, docketing, calendaring, and people management.
The company's technology architecture is anchored by the proprietary Stridyn cloud platform, with MADDI serving as the embedded, pre-trained AI engine across all cloud solutions. Core products include Expert Sierra (the #1 practice and financial management system for law firms), iTimekeep (AI-powered timekeeping with 62.5K+ monthly active users), BillBlast (bill delivery processing 4.5M+ eBills annually), Onyx (OCG compliance automation), Virtual Pricing Director (AI-assisted pricing), and the vi suite for people management. In May 2026 Aderant launched Agent Center, a framework of three AI agents for collections, e-billing appeals, and talent evaluation. The technology stack is supported by integrations with Microsoft 365, AWS infrastructure hosting, and a flagship strategic partnership with Harvey AI.
Aderant operates a sales-led enterprise go-to-market targeting law firm CFOs, COOs, and CIOs, with revenue generated primarily through annual or multi-year SaaS subscription contracts priced on a quote basis by firm size and module selection. Distribution is direct enterprise sales, supplemented by the annual Momentum Global user conference and a content-driven marketing program. The company has grown through serial acquisitions, most recently Virtual Pricing Director in October 2025, and maintains SOC 2 Type 2 certifications across its major cloud products.
