The round was led by growth equity firm Expedition Growth Capital, with key additions to ThreatSpike’s board including Will Sheldon, Partner at Expedition, and Emily Orton, co-founder of Darktrace.
Founded in 2011 by computer scientists Adam and Kate Blake, ThreatSpike was built in response to the complexity and cost of traditional cybersecurity tools. The duo, drawing on their experience in some of the world’s most sophisticated financial institutions, bootstrapped the company to profitability without outside capital—until now.
ThreatSpike aims to replace fragmented, multi-tool security strategies with a single platform that combines advanced technology and expert human support. Its flagship offerings, ThreatSpike Blue (24/7 managed detection and response) and ThreatSpike Red (unlimited penetration testing), are used by more than 200 customers across 90 countries in sectors including hospitality, industrials, investment management and professional services.
“Cybersecurity has become far too complicated and costly for most organisations,” said CEO Adam Blake. “We take a fundamentally different approach—transparent pricing, no aggressive upselling, and a focus on delivering real-world protection. With this investment from Expedition, we’ve found a partner that shares our values and can help us scale our platform globally.”
Investor Will Sheldon said ThreatSpike’s strong organic growth and customer retention set it apart. “This is the highest level of customer referral-driven growth and satisfaction we’ve seen in the cybersecurity sector. We’re thrilled to partner with Adam and Kate as they continue building an innovative and outcomes-focused platform.”
The company plans to use the funding to expand its engineering, security operations, and go-to-market teams while accelerating development of its core product roadmap. This includes further investment in automation, behavioural analytics and real-time threat detection across cloud and hybrid environments.
Darktrace co-founder Emily Orton, who joins the board as a non-executive director, called the founders “impressive entrepreneurs” and said she looks forward to helping them scale the business during its next phase of growth.
Longtime customer Inchcape Shipping Services praised the firm’s reliability and innovation. “ThreatSpike has consistently delivered on their promises and gone above and beyond to tailor their services to our evolving needs,” said Lee Scott, Head of Cyber Security. “We trust them completely with our cyber defence.”
As demand grows for simplified, outcomes-based cybersecurity in an increasingly fragmented market, ThreatSpike is positioning itself as the antidote to complexity—offering a fully managed, single-platform solution for enterprise-grade protection.
