Our story

Born in Cyprus
based in London

Our founder Christos Pishias has always done things differently. Super-commuting between his island home in coastal Cyprus where he lives with his wife and children and ROI(ή) HQ in buzzing central London, he has dedicated the past 20 years of his life to helping social good organisations do better. Working primarily with teams in health, education, charity and local government, Christos brings a bold but evidence-based approach to consultancy for social good and can confidently help solve even the most complex problems faced by purpose-driven organisations.

Since establishing ROI(ή) in 2005, he has expanded the agency to offer a full suite of consultancy services and grown a team of carefully selected experts in specialist consultancy areas. Christos lives and breathes the sector and is driven by a core belief in the importance of helping others.

ROI Operations Director and CEO


Know your community

We ‘get’ the public and third sector. It’s what we live and breathe. We can help you better understand your community and how to solve the complex issues they face through tailored analytics and insight services. We strongly believe that when you make good decisions based on evidence this makes a positive difference. That’s why we work with our clients to develop the insight models that support their decision-making processes.


Making a difference

We bring together analytical capabilities and subject matter expertise to help clients define, implement and deliver change in their organisations and the people they support. We work with our clients to define the impact they want to make and develop the mechanisms to measure this throughout a project and beyond.
