About Elixirr 

Elixirr International plc is a global consulting firm with a bold ambition: to become the best consulting firm in the world. 

Founded in 2009 to challenge a declining industry standard, we’ve grown from a single vision into a powerhouse of entrepreneurial talent, delivering boardroom strategy through to execution. 

After IPO-ing on AIM in July 2020, Elixirr moved to the Main Market of the London Stock Exchange in July 2025. In that time, our market cap has grown from £98 million to over £350 million – a testament to our differentiated approach and relentless pursuit of excellence. 

With a presence across the UK, US, EU, and South Africa, and a client base spanning industries and geographies, we’ve welcomed seven boutique firms into the Group. This has broadened our capabilities across creative, digital marketing, data and AI, procurement, transformation, and more. 

Our vision of becoming a services unicorn is firmly within reach – and this is just the beginning. We’re looking for exceptional talent to join us on this exciting growth journey and shape the future of consulting.
