Our Partners


Our Partners

Equation Research

Our preferred partner for quantitative research and analytics is Equation Research, a full service strategic research agency working with an extensive list of fortune 1000 clients.  

We have worked together on many projects, always with the same values at heart:

  • One size does not fit all - Equation believes in a tailored approach rather than tying clients to a specific methodology or model.
  • Humans aren't lab rats - Equation employs innovative interviewing methods that reflect how people make choices in the real world.
  • Business focus, not a research focus - Equation always stays focused on business outcomes for clients.



We partner with +rehabstudio, a digital design and production company, in a process called Triage. It's a rapid research and prototyping process for branded experiences
and products.

The Triage process is a series of short creative and technology sprints, where we ideate, hack and prototype concepts, while developing insight into the user’s needs. 

Founded in 2005, rehabstudio has a team of over 75 people and offices in Belfast, London and New York.

The studio creates interactive advertising, marketing and products - the project output covers a wide range of
digital experiences including desktop, mobile, social and physical.
