Sam Kendall

Founder & Director

Sam is the founder of Harpoon Consulting. He started in the recruitment sector before transitioning over to work as a digital transformation consultant for central government, where he specialised in building out full delivery teams for government technology projects.

“I founded Harpoon Consulting because I saw a growing need for specialized expertise in securing and optimizing operational technology environments. As industries evolve and become more interconnected, the risks and complexities of managing critical infrastructure continue to rise. I wanted to create a consultancy that not only understands these challenges but also provides practical, hands-on solutions tailored to each client’s unique needs. What makes Harpoon Consulting different is our holistic approach. We don’t just offer one-off services; we partner with our clients to provide end-to-end solutions, from strategic OT security frameworks to resource management that fills critical skill gaps. Our focus is on delivering real-world results that drive enhanced security, scalability and improved efficency for the long term.”
