Inside STI: Building a Culture of Excellence and Collaboration

STI’s transformation over the past two years has not only reshaped the business operationally but has also marked the beginning of a renewed internal culture focused on excellence, collaboration, and accountability.

Following a period of change and transformation, the company has strengthened its foundations by developing clear values, improving communication across teams, and creating an environment where people can take pride in their work. These values of being capable, transparent, reliable, enjoyable, and accountable are now embedded in how STI operates every day.

The emphasis is on delivery and teamwork. Across both the Hook and Poynton sites, colleagues are encouraged to share ideas, take ownership, and work together to solve complex challenges for customers. This collaborative approach underpins STI’s reputation for quality and reliability, attributes that are critical in the defence and aerospace sectors.

With new leadership under Chief Executive Tom Garvey and the support of investor, Rcapital, the business continues to build on this progress, reinforcing a culture that values performance and integrity while supporting personal growth and development.

“STI’s people are our greatest strength,” said Tim Hair, Chairman. “Our focus is on creating an environment where individuals can excel, teams can collaborate effectively, and customers can rely on us to deliver every time.”

As STI enters its next phase of growth, its commitment to excellence, transparency, and collaboration remains central to the company’s success and its role as a trusted partner in the UK defence supply chain.
