Our story

From in-house to independent

Catalyst started as an internal marketing function within Shire Leasing PLC, created to support and market to its extensive existing customer base. As demand and capability grew, Catalyst was established as an agency in its own right.

This marked our move to the centre of Birmingham and the start of operating as an independent business.

Sarah & Paul take over Catalyst

The business had been in operation for six years, but had been in decline, accruing large director’s loans. As a result, the director was let go.

This is when existing co-owners, Sarah Groves and Paul Houston, were headhunted. It was their job to turn things around, and that’s exactly what they did…

Growth through tough economic times

Fast forward five years, we’ve seen Brexit, Covid and a recession, but Catalyst is still here and stronger than ever before.

All director’s loans were paid off, turnover had increased by over 70%, and FY 2021/22 achieved the highest net profit in the 10-year history of the business.

As of January 2023, Paul & Sarah now own 100% of the business.

Scaling the agency

In January 2025, Catalyst rebranded to reflect our growth as an agency and the breadth of specialist skill sets across the team, with search, websites, content, brand, social and CRM each given a designated colour to clearly define how we deliver integrated growth.

We also opened our first overseas office in Dubai, enabling us to better support clients operating across the UK and Middle East.

Alongside this, we launched a dedicated PR arm, led by Dean Enon, strengthening our ability to deliver reputation-led growth, thought leadership, and media coverage as part of a fully integrated marketing strategy.

Leadership expansion & brand launch

At the start of 2026, Catalyst expanded its management team to support continued growth. Shannon Morrall and Nick Floyd joined Sarah and Paul from within the business, alongside Dean Enon, Director of Catalyst PR, strengthening leadership across the agency.

With a strong management team now in place, Catalyst is on track to deliver its highest turnover on record, driven by long-standing client relationships and consistent results.

Alongside this, Catalyst launched a dedicated brand arm led by Lee Jones, further strengthening our specialist offering and supporting the next phase of the agency’s growth.
