Accordion Partners, a new model financial services firm delivering cost-effective deal and project execution services to private equity firms and corporate development groups, announced the promotions of two senior executives at the company. Sonny Thadani will step into the role of chief of staff, while Mow Wong takes over as the new chief operating officer.

In the chief of staff role, Thadani will lead the recruiting, talent development, prospecting and engagement management process at Accordion. Thadani moves into the new position from his previous role as vice president of Business Development at Accordion. Prior to Accordion, he led a real estate investment sales team at real estate firm BHS, where he focused on client development and investment strategy. He also co-founded ECS, an executive search and consulting start-up focused on finance, technology and healthcare.

As chief operating officer, Wong will lead new client/product channel development at Accordion, the financial matters at the company and the quality control of output to clients. He steps into the new position after serving as a director at Accordion. Prior to Accordion, Wong was a consultant for Solaia Capital Advisors LLC, an operationally focused private equity sponsor making control investments in middle-market companies. Before that, he was vice president in the FIG Investment Banking group at Bear Stearns, where he completed several capital raisings, including initial public offerings, secondary offerings and forward sale equity agreements.

The promotions come on the heels of a string of recent successes for Accordion. Last month, the firm announced the completion of a capital raise led by Eagle Proprietary Investments, a Dubai-based investment firm registered with the Dubai International Financial Centre (DIFC), with additional investments from strategic investors, including Peter Lehrman, of AxialMarket, and Alec Guettel, co-founder of Axiom Law.

“I’m thrilled to announce these promotions that reflect the roles and responsibilities taken on by key leaders of our team, Sonny and Mow, throughout our early growth,” said Nick Leopard, founder and CEO of Accordion. “Sonny and Mow have both been phenomenal assets to the company, and their hard work has helped Accordion to become a pioneering new model in the financial services industry. I look forward to seeing their leadership shape the company in years to come.”
