Origins of Progressive TSL

After a successful career in the energy sector at Enterprise Oil and Shell, Progressive TSL was formed in 2004 by Marianne Walcot (our Founder and CFO). Read more about Marianne’s experiences in her profile interview.

Using her expertise and experience of financial systems, and specifically Infor SunSystems, within the energy sector, she quickly built a reputation for on-time delivery, with the added extras of knowledge and understanding of asset-intensive industries and the ability to challenge and push for the right solution for clients.

Her husband Chris, a highly regarded business systems professional, gave up corporate life in a global IT systems provider shortly after to become the CEO of Progressive TSL. Progressive TSL has since diversified to implement HxGN EAM (formerly Infor EAM), Infor OS and IBM Maximo along with IBM Envizi as part of their solution offering – covering all aspects of finance, asset management, ESG and supply chain.

Progressive TSL has seen demand for their holistic approach to business solutions grow. They now employ more than 30 experienced industry specialist consultants with backgrounds in accountancy, engineering and system administration to deliver on specific aspects of their projects. Most consultants also hold accreditations in Progressive’s partners Infor, IBM and Hexagon products.

We now serve a global client base in asset-intensive sectors, including mining, energy and engineering. The founders still have a presence on all projects.
