Alto Litigation is a powerhouse litigation boutique based in San Francisco representing some of Silicon Valley’s most coveted companies and entrepreneurs in high-stakes litigation and regulatory matters, ranging from securities class actions and SEC investigations to trademark disputes. 

Alto’s lead attorneys received degrees from the nation’s most elite law schools and have successfully represented Fortune 500 companies over the last two decades. The firm represents technology companies, entrepreneurs, officers, directors, employees and shareholders in Silicon Valley and beyond in complex matters. 

Alto prides itself on being lean and efficient, with a close team of litigators achieving positive results for top executives and companies. In addition, Alto’s size allows it to offer alternative rate structures, including flat fee or contingency arrangements when appropriate. The results speak for themselves. On the plaintiff side, the firm has achieved millions in judgments and settlements. On the defense side, the firm has achieved dismissals, arbitration wins, and early settlements. 

These results have not gone unnoticed. The firm and its partners have been consistently recognized for their outstanding work.

In addition, the National Law Journal named Bahram an “Elite Boutique Trailblazer” in 2018.
