We work with organisations to help deliver marketing transformation, enabling more effective and efficient customer conversations. We have significant project experience as well as the ability to deep dive into specific issues and opportunities.

Managing Director Grant Denholm has 30 years database marketing experience, is a Fellow of the Institute of Direct and Digital Marketing and is a certified Lean Six Sigma practitioner. Grant has also spoken at several CRM and Database Marketing conferences and has been a guest lecturer at Edinburgh Business School, Strathclyde University, Caledonian University and Napier University.



The Summercall philosophy is that the customer is at the heart of any successful organisation and our starting point for any project is to interrogate the customer data to fully understand the different purchasing behaviours and patterns across the base. Awareness of the customer journey across online and offline channels is a key driver to understanding the moments of truth where marketing effort is required.


We take customer data and make sense of it, spotting trends, patterns and opportunities to either help business sell more to customers or help them retain their most valuable customers. We then develop these insights into CRM strategies and provide the client's communication teams with powerful propositions.
