About Us

Who We Are

Wavestone US is the North American arm of global management and IT consulting firm Wavestone. Over the past 15 years, we have supported the transformations of more than 200 Fortune 1000 companies across a wide range of industries. Our model is unique in that it leverages a strong peer-to-peer culture, offering a practitioner's perspective on IT strategy, cost optimization, operational improvements, cybersecurity, and business management. It is our mission to help business and IT leaders successfully deliver their most critical transformations and achieve positive outcomes. We drive change for growth, lower cost and risk, and create the trust that gives people the desire to act. We believe in helping our clients to innovate and grow on their own so that they can be successful long after we depart. That is what we call The Positive Way.

Wavestone's IT consultancy in the US was formerly known as WGroup, an IT consultancy firm comprised of consultants with over two decades' experience as former C-suite executives and leaders. It built its reputation on a pragmatic outcome-driven, customer-specific, agnostic approach that optimizes IT operations and minimizes costs. Following the merger of WGroup and Wavestone in July 2019, the Wavestone US brand was officially launched in January 2020.

Our Model

We are more than career consultants. We are industry leaders. Our team is a blend of former C-suite executives and industry leaders, and high-quality talent at all levels who can tackle your most complex issues with a fresh approach. With a globally connected network of 3,000 employees, Wavestone US is designed to help you get results. All our consultants thrive on complex challenges, enjoy blazing new trails, and are committed to your organization’s success.

Our Approach

Whatever your needs, our goal is to help you set new standards of excellence that drive your business forward. Our approach is threefold:

Strategy First

At Wavestone, we believe the more superior the strategy, the more superior the results. We collaborate with our clients, service providers, software partners, and each other to develop a results-driven strategy that adds value to our clients’ projects. Through custom analysis and a robust database of aggregated cost and performance data, we build in-depth financial models tailored to your environment.

Adaptable to Your Business

Though business goals across many organizations may be the same, the path to achieving those goals is different for every client. At Wavestone US, we value these differences in industry, culture, and requirements. We work collaboratively to tailor solutions to answer our clients’ distinct IT needs. Whether we’re setting up unique pricing structures or redesigning operational processes or negotiating outsourcing contracts, there are no requests too big or details too small for our team of experts to consider.

Hands-On Execution

Whether you come to Wavestone US for M&A, shared services, or sourcing advisory, we recommend solutions that look at facts and consider all the possibilities. We’ve built business plans, presented to management committees and Boards of Directors, and had the accountability for achieving results in our own careers. We bring our “been there before” experience to every engagement, we understand the human sensitivities of change, and we drive practical solutions that fit within your culture.
