Our story

Who we are



Reacting to a market demand for better integration and a simpler user experience within Microsoft 365, Microsoft MVPs Suzy Dean and Wes Hackett founded AddIn365.

In a direct response to Microsoft’s expansion of Microsoft 365 capabilities to include new services such as Delve, Stream and Sway, AddIn365 announced a mission statement to help support those organisations wanting to make the most of these new capabilities.

With a product-led approach for cost-certainty and to provide maximum business value, AddIn365 produced three pioneering products, bringing them to market in November 2015: AddIn Intranet for publishing, AddIn Work Hub for productivity and AddIn Analytics for insight. These products revolutionised our customers’ investment in Microsoft by plugging the gaps in the Microsoft 365 platform and bringing together different Microsoft services into set packages, to meet specific business needs.

Within a busy first 12 months of starting AddIn365, Suzy and Wes had secured contracts with some of the world’s largest pharmaceutical, financial and advertising companies. This led to the accelerated growth of AddIn365 to becoming one of the most trusted and pioneering innovators of digital productivity solutions in the Microsoft 365 marketplace.

Microsoft were early and highly vocal advocates of AddIn365, for providing an enhancement and better augmentation of Microsoft services such as Microsoft Teams and SharePoint, which helps Microsoft customers to get return on their investment in Microsoft 365. Microsoft’s unwavering support for the AddIn365 approach is evidenced in Microsoft’s positioning of AddIn365 at their flagship conference Ignite every year since 2017 alongside AddIn365’s Charter Partner status.  


In a year that has delivered new and unforeseen challenges, Addin365 has launched AddIn Modular; a create your own service offering. AddIn Modular is designed to ensure organisations no longer pay for ready-made product packages that are only partially used. You, the customer, can now prioritise and select which product modules you need to meet your business objectives and park those that you don’t.


In partnership with Microsoft, AddIn365 have launched a Viva Connections Dashboard Tile collection, to help organisations boost their productivity using Microsoft’s new Viva Connections mobile experience.

Driving deep personalisation of Microsoft services, the new Tile collections bridge the traditional gap between publishing and productivity experiences.
