Whether that’s using the latest technology to automate processes, provide an outsourced finance function, or leading growing businesses through VC funding rounds and more. In 2019, we were joined by Kate Holden ACA, who brings significant industry experience, business transformation expertise and a strategic vision. Harriet and Marianna make up the team – they make sure our clients are well supported at every interaction. How can we help your business?
