Featured Testimonials

"We very much appreciate the work of Eric, Maria, and the AGC team in advising Booz Allen on its divestiture of its commercial Managed Threat Services business. Their extensive knowledge of the security landscape, deep industry relationships, and close attention to detail resulted in an efficient process and excellent outcome for MTS's various stakeholders. We thank them for a job well done and look forward to working together again in the future."

Matthew Calderone, CFO, Booz Allen Hamilton

"The AGC Team led by Maria and Eric have been extremely instrumental in bringing our acquisition to a successful outcome. The entire team working with us have been super committed to any need or request regardless to time limitations or work hours. Having AGC with us through the process allowed both our board and the deal team to gain confidence that the process is managed well. Would definitely engage again with AGC for future opportunities."

Uzi Krieger, CEO, Reposify

"To us, it was essential that our banker could fundamentally understand the Promon technology and offering. The AGC team quickly gained such understanding. By doing so, they could 'connect the dots' very rapidly; providing us with deep insight into which partnerships would long-term create the greatest return for all parties. On top of that, they don't forget the small details, which ultimately will lead to a timely and satisfactory transaction. We can give AGC our strongest recommendations as an M&A advisor in the IT security industry."

Gustaf Sahlman, CEO, Promon
