Marion Mariathasan's Profile

Marion Mariathasan Related Seminars and Products

Co-Founder & CEO


I have been involved in the cannabis industry since 2015 - initially as an investor.  Today, I serve as the CEO and Co-Founder of Simplifya - the leading regulatory and operational compliance company in the cannabis industry.  SImplifya provides compliance technology for licensed operators, banks, insurance, law firms and consultants. 

I am also the Founder and Chairman of Ceylon Solutions - a software development company that partners to build innovative software in many verticals that includes cannabis.  Some of the more recognized names in cannabis include New Frontier Data, Simplifya, Leafwire and Empyreal Logistics.   

I currently serve on the boards of five different companies - three of which are in the cannabis industry.   As a supporter of the cannabis movement, I have 18 active cannabis investments – two of which are international.   

I immigrated to Kansas from Sri Lanka when I was 7 years old. I attended both University of Kansas and Emporia State University studying Architecture, Computer Science and Computer Information Systems. After graduation, I took on my first technical role with a medical software company. Since then, I’ve been fortunate enough to have held management and executive level positions with incredible companies – large and small. In addition, I’ve been blessed with the opportunity to have either founded or be involved with many new startups over the years – four of which I’m highly involved with even today.

But I have to admit that some of my most valuable experiences have come from travel and from people I’ve had the opportunity to meet along the way. I’ve learned that humility and kindness is a virtue that I admire most about people and that no matter the level of education, wealth, power and status, everyone is equal. 

In my opinion, some of the most important things we can do in this life as human beings is to help others, give back to the community and treat all living things with respect and kindness.

Perkins Coie LLP

Barak Cohen represents two kinds of clients: companies and individuals facing government enforcement actions and investigations in highly regulated industries, particularly the healthcare and government contracting industries, and companies that need strategic business advice regarding compliance and regulatory matters in the cannabis industry. Barak is a partner in the White Collar & Investigations practice, and co-chair of the firm’s Cannabis Law group. He also works with the firm's Digital Media & Entertainment, Gaming & Sports industry group as the co-lead of the Gaming vertical, providing regulatory review and counseling to clients in the regulated gaming industry, including matters involving gambling and sports betting.

A former prosecutor in the U.S. Department of Justice (DOJ), Barak led numerous white-collar investigations throughout the United States. That inside experience informs Barak’s representation of companies and individuals in diverse matters that touch on alleged foreign and domestic fraud and bribery, financial misconduct, tax crimes, false healthcare and government contracting claims, campaign finance and election crimes, antitrust crimes, and environmental crimes. Barak has particular experience representing companies that do business with the government, such as technology companies, medical labs, medical device companies, and pharmaceutical companies, and in investigations regarding the False Claims Act (FCA), the Anti-Kickback Statute (AKS), and the Eliminating Kickbacks in Recovery Act (EKRA), as well as in investigations led by agency inspectors general. He has also represented multinational companies in sensitive international investigations involving international corruptions laws, such as the Foreign Corrupt Bribery Act (FCPA) and the U.K. Bribery Act. Notably, Barak’s work has included representing high-profile public officials, including multiple sitting members of Congress, in investigations regarding alleged campaign offenses and election crimes, as well as in state and federal ethics investigations. Barak is a co-chair of the American Bar Association’s (ABA) Public Corruption Sub-Committee.

With respect to his cannabis practice, Barak was quick to identify the growth potential in the cannabis industry. He works with well-established international brands, multistate operators, and startups, advising on a wide breadth of matters (including marijuana, CBD (cannabidiol), CBG (cannabigerol), and hemp products and services) that intersect with other diverse industries, ranging from e-commerce and technology platforms that facilitate cannabis transactions, to product-handling dispensaries and brands. He is a member of the board of directors of the U.S. Cannabis Council, a vice-chair of the ABA’s Cannabis Law Sub-Committee, and a former member of the National Cannabis Industry Association’s Policy Council. A recognized thought leader in cannabis matters, he edited and co-authored the first-of-its kind treatise, Cannabis Law: A Primer on Federal and State Law Regarding Marijuana, Hemp, and CBD, published by the ABA in February 2021.

Before becoming an attorney, Barak served as an infantry officer in the U.S. Army. He is the co-founder of Perkins Coie’s Veterans Resource Group. Chambers USA: America’s Leading Lawyers for Business has recognized Barak in two areas: (1) Litigation: White-Collar Crime and Government Investigations and (2) Cannabis Law: Eastern United States. Commentators have noted that “he is very savvy," and that "Barak is a fantastic lawyer, cool under pressure and laser-focused."
