SUMMARY

  • London-based cybersecurity company ThreatSpike has raised $14 million (about €12.2 million) in a Series A funding round.

The investment was led by Expedition Growth Capital, a software-focused growth equity firm with offices in London and Boston.

The firm provides funding to help companies grow, gives shareholders a chance to cash out, and supports businesses with expert guidance.

“ThreatSpike has the highest level of customer referral-driven growth and satisfaction that we have seen across the cybersecurity industry,” says Will Sheldon, Partner at Expedition Growth Capital. “The company has been growing rapidly and profitably without investment and we are proud to partner with Adam and Kate as they fuse software and services into a unique platform that delivers tangible cybersecurity outcomes for sophisticated customers globally.”

Along with the funding, ThreatSpike also announced that Will Sheldon from Expedition and Emily Orton, co-founder of Darktrace, have joined its Board of Directors.

“Adam and Kate are both impressive technology entrepreneurs,” says Emily Orton, Co-Founder of Darktrace. “I am excited to join them on ThreatSpike’s board and use my experience to help scale the business in this new phase of growth.”

The funding will help the UK-based ThreatSpike grow globally by expanding its teams in engineering, security operations, and sales. Last year, the company set up subsidiaries in Singapore, France, the USA, the UAE, and China.

“We will be bringing on employees in these countries to support our global customer base in their local languages and time zones. We have grown our development team 300 per cent since taking the investment and built out a GTM team when we had only two people in sales previously and none in marketing,” says Adam Blake, CEO and Founder at ThreatSpike to Silicon Canals.

ThreatSpike currently has around 50 employees and plans to grow the team to 75 by the end of the year. The company will also speed up its innovation efforts across its platform, including ThreatSpike Blue (24/7 managed detection and response) and ThreatSpike Red (unlimited penetration testing).

“Having worked with large companies, we had seen how much they struggled with detecting even basic security threats despite having invested £millions in solutions like intrusion detection, proxies, and SIEM (Security Information and Event Management), as well as having tried to build internal security operations centres. Despite investing heavily, even tier 1 companies had intrusion detection sensors cabled up incorrectly, SIEM solutions with no working rules, broken event feeds, brittle detections, and lacked threat modeling capabilities,” says Adam.

ThreatSpike aims to solve a big problem in cybersecurity: traditional security tools are often scattered and don’t work well together.

“Companies were trying to detect threats by correlating logs from disparate point solutions (e.g. proxies, intrusion detection, OS, firewalls), but the logs were in totally different formats, often missing key details and companies had all kinds of different solutions, or even none at all,” explains Adam.

This lack of standardisation in security systems created a major gap in detecting and understanding threats.

“The most urgent priority was to create a standardised set of data from which you could detect and investigate threats. To do this, we built the first engine capable of monitoring network traffic (which is standardised across all networks) and generating telemetry event data to describe what was happening. So if a user uploaded a file or logged into a file share, then the events were always generated irrespective of what technology platforms the company had deployed or what security solutions they were using,” adds Adam.

ThreatSpike makes cybersecurity easy for businesses with an all-in-one platform that tackles the high costs, complexity, and gaps caused by using too many different tools.

It provides key protections like real-time threat detection and unlimited penetration testing, helping companies stay safe from evolving cyber threats.

Based in the UK, ThreatSpike’s AI platform tracks billions of events daily across hundreds of thousands of users, with expert analysts working around the clock to keep customers secure.

“We use AI to speed up triage and remediation of incidents, as well as detect more complex attacks. With AI, we can triage and respond to incidents within 3 minutes, compared to humans who take at least 15 minutes or even hours, depending on their workload,” explains Adam.
