Riveron acquires Effectus

Riveron, a Dallas-based national business advisory and consulting firm backed by Kohlberg & Co., has acquired Effectus Group, a San Jose-based accounting advisory and financial operations firm specializing in advising technology and life sciences companies. 

The move bolsters Riveron's presence in the San Francisco Bay area and builds its accounting, finance and capital markets experience. Effectus includes alumni from the Big Four and offers managed accounting and risk advisory services.

Riveron has over 1,180 professionals, while Effectus has more than 150.  "The partnership with Effectus Group represents a pivotal step in Riveron's growth strategy," said Riveron CEO Sam Shaw in a statement Tuesday. "Their deep expertise in technical accounting, capital markets, and their strong presence in the life sciences and technology sectors complement our existing strengths. Together, we are well-equipped to provide unparalleled service to our clients, particularly in the fast-evolving venture capital and public markets spaces."

Riveron has been growing in Southern California and New York City and will be serving an even broader range of clients in high-growth markets.

"Joining forces with Riveron allows us to accelerate our growth and expand our service offerings to a wider audience," said Effectus Group CEO Mike Montgomery in a statement. He  will take on a senior leadership role at Riveron as well as retain significant equity ownership in the combined company. "Our cultural alignment, combined expertise, and shared passion for helping our clients succeed make this a natural fit."

In 2022, Riveron acquired Clermont Partners, a women-owned consultancy based in Chicago that focuses on environmental, social and governance communications and strategy, investor relations and transaction communications.
