In 2024, TowerBrook Capital Partners became our majority equity investor.

TowerBrook is a purpose-driven investment firm with deep experience in industrial infrastructure – including aerospace, automotive, construction, and transformative technologies.

It’s an exciting evolution for JSM. But while our capacity has changed, our DNA has not. We remain founder-led. John Scanlon (COO) is still running the business, alongside Michael Booth (CEO). We now have the backing to expand our customer base, enter new international markets, and invest in capability at pace – without losing what made us succeed in the first place. Expect the same entrepreneurial drive, now powered for scale.

Upon acquisition, Joseph Knoll and Sumit Dheir of TowerBrook said:

“We are excited to be working with the founders and management team at JSM. We have spent several years following the infrastructure services sector and JSM stood out as an exceptionally high-quality asset with an impressive development in the past few years. We are convinced that with our extensive industrial services experience we are the right partners to support the founders and management team in the next phase of growth, both in the UK and internationally.”
