WilliamsMarston acquires AIT Consulting Services

WilliamsMarston, a Boston-based accounting and consulting firm, has acquired AIT Consulting Services, a Houston-based OneStream Software consulting firm.

Founded in 2018, AIT is a diamond partner for OneStream, an enterprise finance management platform. The firm helps enterprises and private equity-backed companies implement and optimize solutions in financial consolidation, budgeting and forecasting, and monthly close processes.

AIT has 37 employees listed on LinkedIn and has completed over 250 OneStream projects since its founding. The firm says over 30% of its employees are CPAs.

WilliamsMarston’s acquisition of AIT will expand its service offerings for the Office of the CFO.

“AIT’s technical expertise, strong client relationships, and values-driven culture make them a natural fit for WilliamsMarston,” said Sanjay Ramaswamy, CEO of WilliamsMarston. “With the integration of AIT, we’re now uniquely positioned to deliver more integrated and scalable solutions to CFOs and Controllers nationwide.”

WilliamsMarston was founded in 2014 and has more than 250 professionals across eight US offices. The national firm provides accounting, tax, valuation, and transaction advisory services to pre-IPO, public, and private equity-backed companies.

“We are thrilled to join forces with WilliamsMarston,” said Ryan Diehl, Ben Novak, and Mathew Shirley, managing directors of AIT Consulting Services. “This partnership gives our clients access to a broader range of services while providing our team with exciting new opportunities for collaboration and growth.”
