Founded by Boris Onefater (CEO and co-founder) and Greg Farrington (President and co-founder), Constellation Advisers provides comprehensive customized solutions to a range of traditional and alternative investment management firms including Private Equity, Real Estate, Private Credit, Venture Capital, Hedge Funds and Family Offices.

Employing 115 professionals located across its six U.S. offices – New York (HQ), Dallas, San Francisco, Los Angeles, Chicago and North Carolina – Constellation Advisers provides a high touch, customized, boutique style service.

Following this acquisition, IQ-EQ’s newly combined U.S. business totals more than 320 U.S. based employees with scale in regulatory compliance, fund administration and outsourced services, providing the Group with significant cross-sell opportunities and a solid footprint for continued future growth in the U.S.

Services provided include: 

  • Outsourcing of accounting, CFO and financial services
  • Outsourced COO services including middle office, operations and trade support mainly to the buy-side dealing with the public / liquid markets
  • Compliance and regulatory services including program design, surveillance and ongoing maintenance 
  • Business advisory and consulting services to support projects including fund set-up, due diligence, strategy development and wind downs

This acquisition confirms IQ-EQ’s commitment to the U.S. market, the largest and fastest growing fund services and regulatory compliance market in the world, and takes the Group one step closer to achieving its strategic objective of becoming the leading independent investor services provider globally.

With immediate effect, Mark Fordyce, CEO of Blue River and IQ-EQ U.S. Funds, will assume overall responsibility for the Group’s expanded U.S. operations. Constellation Advisers co-founders, Boris Onefater and Greg Farrington, will assume the roles of Chairman, Global Head of Outsourced Services and President and Head of Outsourced Services, Americas, respectively.

IQ-EQ will retain the Constellation Advisers brand name in the short to medium term and will move to rebrand the business to IQ-EQ as part of its longer term business strategy.

Speaking about this transaction, IQ-EQ Group Executive Chairman Serge Krancenblum commented:

“I’m delighted to start 2021 on such a hugely positive note and to welcome Boris, Greg and the rest of the Constellation Advisers team to IQ-EQ. This latest transaction represents yet another significant milestone made possible by the ongoing investment in our U.S. operations and takes us one step closer to realizing our longer term commercial ambitions in the region. Constellation Advisers’ sector expertise and singular focus on delivering client service excellence make them a strong and natural fit for our business and an important part of our U.S. expansion plans.”

Mark Fordyce, CEO Blue River and IQ-EQ U.S. Funds, added:

“The acquisition of Constellation Advisers enhances IQ-EQ’s position in outsourced and co-sourced back-office solutions for the U.S. alternative asset industry. The addition of the 100+ Constellation Advisers team brings the total U.S. headcount to more than 320, giving the combined firm increased scale and presence in all key financial markets across the U.S. and the ability to successfully leverage the depth and strength of the entire IQ-EQ Group operating across all of our 23 strategic jurisdictions around the globe. I look forward to working closely with Boris and Greg and building the premier service provider to the U.S. alternative asset industry.”

Commenting on this transaction, Boris Onefater, Constellation Advisers CEO, said:

“Greg and I along with the entire Constellation management team are delighted to join the IQ-EQ family.
