Charles Clark, CEO

Charles is an experienced and well-regarded senior executive. He co-founded Rosslyn Data Technologies Plc and Darkbeam whilst also serving as an advisor for a number of other successful technology and investment companies.

Charles’ particular interest is helping young companies achieve their dreams. With an MBA from City University Business School, Charles focuses his skills on raising capital, building sales distribution channels and marketing.

Prior to this he was an Executive Director of the asset management division of Panmure Gordon, managing £1.3bn globally, where he had a particular interest and focus on technology.

Charles’ passion for intelligence insights stems from his time serving with the British Army where he served on active service in theatres of operation. Today, Charles is proud to be a mentor for ex-servicemen and actively supports charity work. When he’s not busy trying to change the world, Charles loves his golf!

Justin Leary, COO

Justin Leary is a former Police Officer with a background in intelligence. Working as both a practitioner and a manager within the Metropolitan Police Service, Justin had roles in the Telecommunications Intelligence Unit and the Open Source Unit – using the internet as an investigatory tool.

Justin was also project lead on a change program aimed at implementing and improving open source capabilities and social media analytics across the organisation ahead of the 2012 London Olympics.

Since leaving the police service, Justin has performed a number of roles focused around providing open source and analytical software designed specifically for law enforcement and public sector practitioners.

Today as a co-founder of Darkbeam, Justin is dedicated to bringing his domain expertise to Darkbeam clients and helping organisations to thrive in complex risk environments.


Steve Tyrens, CTO

As Chief Technology Officer at Darkbeam, Steve heads up our research efforts and leads the development team to deliver a consistently evolving offering in the threat visibility space.

Previously serving as an intelligence analyst in the British Armed Forces, Steve has more than 20 years of experience in the development of IT and cybersecurity solutions.

He co-founded Darkbeam with Justin to address what he saw as the indefensible lag in actionable threat intelligence needed by technical teams to defend against cyberattacks and bad actors.

Never afraid to build something innovative or challenging, Steve was first placed military contestant in the GCHQ/US Department of Defence Cyber Forensics Competition in 2013.

Today, Steve's focus is on building a new generation of risk visibility and threat assessment tools to protect Darkbeam users from attacks via their supply chain.

Jet White, Head of Development

As Head of Development, Jet is responsible for the delivery of the Darkbeam platform.

His experience spans a wide range of sectors, including a number of years delivering significant full-lifecycle projects for big players in UK government cyber intelligence, as well as a range of public sector organisations. More recently he has been delivering highly respected and successful products in the EdTech sector.

Jet's passion and interest in engineering is not just limited to software. His background and experience in electronic, automotive and civil engineering gives him a unique approach to delivering complex projects.


Andrew McConnell, Partner Manager

Andrew joins us to manage Darkbeam’s customer and partner community. With more than thirty years’ experience working in commercial roles within the IT industry Andrew brings a wealth of relevant knowledge.

Prior to Darkbeam Andrew has also managed major partners for the likes of Cisco and Rackspace, as well as being a divisional manager in the Morse Group.

In his downtime Andrew’s real passion is scuba diving, with his annual trips to far-off and exotic dive sights only being interrupted by the need to earn enough money for the necessary funding.
