“Everything here is great. He knows what he’s doing. He’s a thoughtful leader with a smart approach so far, not a bull in a china shop. He triaged our marketing team and was mindful, smart, and graduated in terms of goals. He didn’t try to do everything at once and did exactly what I hoped he would do. His energy & ideas are being embraced throughout the firm.”

James J. Stapleton
For nearly two decades, James Stapleton has driven business development, marketing, and client service excellence as the head of these functions at four prominent AmLaw 100 firms in the United States, including Blank Rome, Dickinson Wright, Littler, and Fenwick & West. Across those firms, he built industry sector-specific business development platforms.
His proven track record in accelerating organic growth, enhancing client relationships, and leveraging data-driven strategies has positioned him as a trusted advisor in the legal industry. His leadership coincided with:
Transformational improvements in institutional client development
Sector penetration unlike any other law firm
Client satisfaction improvement
Record growth rate & AmLaw ranking improvements
Today, as Managing Principal of Client Sciences—a Silicon Valley-based firm founded in 2023—Mr. Stapleton partners with both corporate clients and law firms to optimize legal service ecosystems. For corporate clients (including in-house legal departments), he helps:
Cultivate an optimal mix of law firms and alternative legal service providers (ALSPs) through AI-powered evaluations and sector-specific indices.
Enhance the overall client experience with external legal providers via proprietary frameworks like the Client Code of Service Excellence.
Maximize value from legal spend by shifting to predictable, value-based fee structures and improving operational efficiency.
For law firms, he provides strategic guidance to:
Deepen industry sector penetration using custom indices (e.g., Sector Penetration Index and Client Service Excellence Index) that benchmark performance in areas like Life Sciences.
Boost revenue generation through advanced business development, proposal optimization, and client feedback integration.
Build high-performing marketing and sales teams, drawing on his experience in restructuring departments and training rainmakers.
This dual-sided approach ensures mutually beneficial relationships, informed by thousands of client feedback interviews, post-mortem analyses, and over 7,500 proposal processes.
