Acquisition now positions consulting firm Riveron as a leader in accounting advisory

Riveron (or the “Company”), a leading business advisory and consulting firm backed by Kohlberg & Company, today announced the acquisition of Effectus Group, a San Jose-based accounting advisory and financial operations firm specializing in advising high-growth technology and life sciences companies. This strategic move significantly enhances Riveron’s presence in the San Francisco Bay Area and builds depth in core accounting, finance, and capital markets capabilities, reinforcing its position as a premier advisor to the office of the CFO.

Scale to address clients’ capital markets and accounting advisory needs

The partnership with Effectus expands Riveron's already robust accounting advisory services. The talent pedigree at Effectus includes “Big Four” accounting firm alumni, and its leading technical accounting and capital markets prowess aligns well with Riveron’s existing capabilities. Both firms are adept at supporting client organizations through transformation and growth—across the venture capital and private equity arenas, IPO readiness, and beyond.

Further benefitting the office of the CFO, Effectus’ managed accounting and risk advisory capabilities blend well with Riveron’s long-term focus on helping clients solve their day-to-day operational accounting and GRC needs, respectively.

With more than 1,200 professionals across Riveron, this combination creates a strong team of 300-plus accounting advisory professionals uniquely positioned to deliver comprehensive solutions to clients.

“The partnership with Effectus Group represents a pivotal step in Riveron’s growth strategy,” said Sam Shaw, CEO of Riveron. “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.”

Expanded market reach and alignment to client-centric culture

This combination strategically broadens the firm’s reach into key markets. Building on Effectus Group’s strong presence in the San Francisco Bay Area and Riveron’s ongoing growth in Southern California and New York City, the combined firm is poised to serve an even broader range of clients in high-growth markets across the country.

“Joining forces with Riveron allows us to accelerate our growth and expand our service offerings to a wider audience,” said Mike Montgomery, CEO of Effectus Group, who 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. We are excited to continue our work in the technology and life sciences sectors while also leveraging Riveron’s strengths in private equity and broader office of the CFO capabilities.”

“Our focus has always been on achieving great outcomes for our clients,” added Shaw. “The combination of Effectus with Riveron enhances our ability to tackle the most complex challenges facing CFOs today. Together, we will exceed the high standards of service and expertise that our clients expect.”

The Effectus partnership reinforces a marked period of client-centric growth for Riveron, as the event closely follows Riveron’s acquisition of Yantra a few weeks prior, which strategically expanded Riveron’s business transformation capabilities and breadth of end-to-end technology solutions tailored for the office of the CFO and private equity-backed organizations.

Guggenheim Securities, LLC and Blue River Financial Group served as financial advisors and Baker McKenzie served as legal advisor to Riveron. Haynes Boone served as legal advisor to Effectus Group.
