Keyfactor, the trust infrastructure specialist for the AI and quantum era, has received a strategic growth investment exceeding $1bn as enterprises race to secure machine identities ahead of the post-quantum transition.
The round was led by Summit Partners, with existing backers Insight Partners and Sixth Street Growth retaining substantial stakes once the deal completes. The fresh capital is earmarked for scaling the business globally, funding product development, entering new geographies, hiring, and pursuing acquisitions. Summit Partners managing directors Andy Collins and Colin Mistele will both take seats on Keyfactor’s board when the transaction closes.
The deal lands as several pressures collide to push trust infrastructure onto boardroom agendas. Machine identities now vastly outnumber human ones and are multiplying more quickly than businesses can cope with using disparate tools and manual workflows. At the same time, certificate lifespans are getting shorter, regulation is tightening, and organisations face the shift to post-quantum cryptography. Policymakers are adding to the pressure, with the White House issuing executive orders in June 2026 designed to speed the US transition to post-quantum cryptography before 2030.
Keyfactor enables organisations to govern digital trust through a single unified platform rather than a patchwork of disconnected products. Its Trust Control Plane gives businesses centralised visibility over machine identities, cryptographic assets and trust systems, automating lifecycle management and enforcing consistent governance across cloud, on-premises and hybrid environments, covering devices, workloads and AI agents.
The CyberTech firm is growing from a strong financial base, with accelerating annual revenue growth and sustained profitability. It issues and manages billions of machine identities each year for more than 2,500 customers globally, counting half of the largest banks in the US and Europe, 80% of leading US retailers and over 40% of Fortune 100 companies among them. It also holds deep footholds in financial services, technology, healthcare, telecoms and the US federal government, having gained FedRAMP certification earlier this year to serve federal agencies with cloud-based certificate lifecycle automation.
Keyfactor CEO Jordan Rackie said, “Trust infrastructure has become the foundation that every enterprise, government agency, and AI-driven organization depends on, and Keyfactor is the platform built to manage it at scale. This investment is a powerful validation of what our team has built and where we are headed. Summit Partners shares our conviction that the opportunity in front of us has never been larger, and this partnership gives us the resources and runway to capture it. For our customers and partners, this is a moment of continuity and acceleration: the same leadership, the same mission, and an even stronger platform.”
