Simplify Jobs

Simplify's Take

What believers are saying

  • AI-ready talent and cyber training are expanding priorities for banks and public employers.
  • CAPSLOCK joining mthree in June 2026 broadens cross-sell into security-skills budgets.
  • The merged group gains scale for cross-selling staffing, upskilling, and expert consulting services.

What critics are saying

  • Inspirit owns mthree and Peregrine, so portfolio leverage pressure constrains strategic flexibility.
  • Hiring depends on employer demand in finance and tech; contract slippage hits utilization fast.
  • If clients internalize graduate training, mthree's hire-train-deploy model loses its core value proposition.

What makes mthree unique

  • mthree merged with Peregrine in January 2026, combining private and public-sector HTD reach.
  • CAPSLOCK acquisition adds cyber, AI, and digital resilience training to mthree's pipeline.
  • Custom hire-train-deploy programs place 250+ people across North America, EMEA, and APAC.

Mthree acquires CAPSLOCK to boost cybersecurity training capabilities

London-based training provider Mthree has acquired cybersecurity education firm CAPSLOCK to strengthen its capabilities in cybersecurity, artificial intelligence and digital resilience training for finance, technology and public sector employers. Founded in 2019, CAPSLOCK has trained over 1,200 adults for cyber careers, working with organisations across financial services, telecoms, aerospace, defence, manufacturing and broadcasting sectors. Mthree CEO Alex Headley said cybersecurity and AI are workforce challenges as much as technology issues, noting employers cannot rely solely on hiring from a limited pool of experienced specialists. CAPSLOCK co-founder Lorna Armitage said joining Mthree provides a platform to expand their mission of removing barriers to cybersecurity careers as cyber and AI risks grow more complex.

Leumi ABL backs Mthree–Peregrine merger with £10M facility

Leumi ABL has provided a £10 million asset-based lending facility to support the merger of Mthree and Peregrine International Limited, both portfolio companies of UK private equity firm Inspirit Capital. The deal combines Mthree's private sector recruitment focus with Peregrine's public sector operations in the hire-train-deploy market. The merger aims to deliver increased scale, strengthen management and unlock cross-selling opportunities across both sectors. This marks Leumi ABL's third financing arrangement with Inspirit portfolio companies, following its backing of @Spaldings Ltd's acquisition in June 2023. The combined group operates across the UK and US. Inspirit Capital highlighted asset-based lending's flexibility and scalability for PE-backed businesses, whilst Leumi ABL emphasised its expertise in cross-border transactions and understanding of private equity requirements.
