Manager, Client Services (Private Equity)

Every day, somewhere in the world, important decisions are made. Whether it is a private equity company deciding to invest millions into a business or a large corporation implementing a new strategic direction, these decisions impact employees, customers, and other stakeholders. 

Consulting and private equity firms come to proSapient when they need to discover knowledge to help them make great decisions and succeed in their goals. It is our mission to support them in their discovery of knowledge. 

We help our clients find industry experts who can provide their knowledge via interview or survey: we curate this knowledge in a market-leading software platform; and we help clients surface knowledge they already have through expansive knowledge management.  

We’re hiring a Client Services Manager to help scale our Private Equity business at proSapient. 

This is a hands-on leadership role for someone who thrives in high-pace, high-expectation environments and wants real ownership: of people, of clients, and of outcomes. You’ll build and lead a high-performing team, partner closely with senior PE clients, and help define how proSapient scales its Private Equity offering through consistently high-quality, insight-led projects. 

You’ll sit at the intersection of people leadership, client strategy, and commercial performance, reflecting proSapient’s values while helping define what excellence looks like in our Private Equity offering.

Project Management: 

• Oversee the delivery of multiple, fast-moving Private Equity projects, ensuring quality, speed, and consistency.

• Build trusted, long-term relationships by understanding investment strategies and portfolio needs.

• Work closely with commercial and delivery teams to turn client insight into action. 

People Management: 

• Lead, coach, and develop a team of client services professionals (from Associate to Team Lead). 

• Create an inclusive, high-performance culture with clear expectations and regular feedback. 

• Plan team capacity and resourcing to meet demand without compromising quality. 

• Support career development and progression as the PE team continues to scale. 

• Key previous experience needed for this role includes:
