Exclaimer is an accredited Microsoft Gold partner and its products support the full array of Microsoft‘s email solutions including MS Office 365, Microsoft’s rapidly growing cloud deployed business platform. Exclaimer’s software gives users complete flexibility and control over email signatures and disclaimers. This helps to ensure regulatory compliance whilst also enabling consistent brand promotion and innovative marketing campaigns.


Signing off global success

  • Our investment is helping the business invest in expanding relationships with partners, add scale by broadening its suite of products and invest further in infrastructure and customer services to ensure Exclaimer capitalises on its market leading position.
  • Our in-house talent team is working closely with Exclaimer to augment its senior team at pace. We introduced a chairman, CEO, CFO, CMO and CTO since completion, enabling the founders to step back from the business. 
  • In 2019, Exclaimer featured in the Sunday Times' Profit Track's Ones to Watch guide, which seeks to identify British firms that have either had or predict good profit growth, with selection criteria looking at the strength of their management, the challenges they have overcome, innovation, past growth and future prospects.


“In the last 16 years we have taken a very simple concept and turned it into a global success.  The investment from Livingbridge will enable us to push on even further, adding scale and firepower to our business while still maintaining our entrepreneurial culture of innovation to ensure our customers continue to receive excellent product and services. We are delighted to be working with the Livingbridge team and I know I speak on behalf of the whole team when I say that we are incredibly excited about our future.”
