New Platform Investment to Further Accelerate Rapid Growth Amid Escalation in National Cyber Threat Landscape

ARLINGTON, Va., November 15, 2023-- Washington Harbour Partners LP (“Washington Harbour”), a leading private investment firm that specializes in partnering with founders and management teams to unlock their next phase of growth, announced today it has acquired SIXGEN Incorporated (“SIXGEN”), a world-class cyber solutions company for the U.S. national security, intelligence, and defense communities, and critical commercial industries.

“We are thrilled to have this opportunity to partner with SIXGEN and help them continue their growth journey,” said Mina Faltas, Founder and Chief Investment Officer of Washington Harbour. “In SIXGEN, we see a company with best-in-class capabilities, outstanding reputation and qualifications, and a strong culture of excellence in delivery and commitment to the national mission.”

The acquisition of SIXGEN is a natural fit for Washington Harbour’s operational and domain expertise in high-growth companies in non-cyclical industries, including government services, defense technology, cybersecurity, software, and tech-enabled business and consumer services. SIXGEN will continue to be led by the Company’s founder and CEO, Ethan Dietrich.

Mr. Faltas added, “The national security cyber domain and threat landscape is rapidly evolving, and we are aligned with Ethan’s strategic vision for SIXGEN, bringing their exceptional talent and solutions to every corner of our national cyber needs. We look forward to investing behind our shared intent to accelerate growth and make a broader impact on our nation’s security. SIXGEN is a truly innovative technology-enabled cyber firm, and it’s an honor to partner and further their position as a leader in high assurance, zero trust security."

"Mission impact is in our DNA. The shared values we have around innovation and technological advancement create massive possibilities to shift the cyber landscape to our country’s advantage," said Ethan Dietrich, CEO of SIXGEN. "Our partnership with Washington Harbour will bring significant financial, strategic, and operational resources as well as global cyber expertise to help us in our next stage of evolution. Our aim is to fundamentally alter the landscape in which we operate, addressing our customers' ever-evolving needs and serving the unique and critical missions of our government. Together with Washington Harbour, we will make larger impacts and significant leaps forward in national cyber capabilities."

This acquisition is Washington Harbour’s second platform investment in the U.S. Federal Government IT sector. As a market leader and innovator, SIXGEN’s cyber services and high-end product suite are critical to the national security mission and designed to meet the unique and specific needs of the nation’s most important cybersecurity problems. With a world-class team of operators, pioneering developers and engineers, and cyber data science and threat prediction utilizing cyber-AI platforms, SIXGEN offers industry leading red team capabilities, with bespoke expertise in emulating and assessing real-world threats, supported by a portfolio of next generation intellectual property.

“The excitement around this partnership transaction has created a number of unique and strategic opportunities for our next chapter as a pioneering cyber solutions company that I look forward to capitalizing on alongside all of our SIXGEN teammates and partners,” said Shawn Devroude, SIXGEN’s Chief Strategy Officer. “Since joining SIXGEN earlier this year after a 20-year career in national security operations with the FBI, I have been keen on bringing our cutting-edge cyber solutions to new and existing customers across DoD and the US Intelligence Community, while also forging key partnerships within the cyber capabilities industry. Our partnership with Washington Harbour will only further strengthen our potential and underpin our industry leading offerings.”

"SIXGEN has cultivated a team of world-class cyber operators who aim to solve the most difficult challenges faced by their customers with a focus on innovation and customer mission success," said Ralph Kahn, Operating Partner at Washington Harbour. " One of the biggest challenges in the cyber space today is developing and deploying new cutting-edge cyber solutions quickly and at scale. With SIXGEN’s world class capabilities combined with Washington Harbour’s resources, I believe we can quickly make a game-changing impact that will strengthen our nation’s cybersecurity at scale. We look forward to supporting the continued growth of the business to further enhance and accelerate the team’s impact on customers and the nation."

Washington Harbour was advised by Crowell & Morning on legal matters and PwC on financial. Holland & Knight served as the legal advisor and KippsDeSanto & Co. served as financial advisor to SIXGEN.
