EfficientEther Appoints Barry Flanagan to Support US Growth
Barry Flanagan joins EfficientEther as Non-Executive Director and US Sales Advisor to grow its US customer base and MSP relationships.
On 29 October 2026, EfficientEther announced that it has appointed Barry Flanagan as a Non-Executive Director and US Sales Advisor to support its next phase of commercial growth. Barry joined the board in October 2026, and his focus is on developing the company's US customer base and its relationships with managed service providers (MSPs) across the Microsoft-focused software portfolio.
About Barry
Barry brings more than 25 years of enterprise technology, sales and alliance experience, including senior roles at Citrix, VMware and ControlUp.
As Non-Executive Director and US Sales Advisor, he will advise CEO Ryan Mangan and the board on commercial strategy, US market development and partner opportunities.
Why this matters for IT teams and MSPs
EfficientEther's growth priorities are to reach more IT teams, expand its partner network and increase adoption of EtherInsights, EtherAssist and EtherApps Forge.
The portfolio addresses practical priorities for organisations running Microsoft environments:
- Controlling cloud and licence costs, the work behind cloud cost optimisation.
- Improving IT support and compliance, covered in IT operations and compliance.
- Preparing applications for modern Windows and Cloud PC deployments, from legacy application readiness to Windows 365 migration.
For MSPs, these capabilities support services spanning assessment, migration and ongoing management. If you run Microsoft 365 for customers, see Microsoft 365 for MSPs and the EfficientEther partner network.
In their words
Ryan Mangan, CEO of EfficientEther, said:
Our ambition is to grow EfficientEther's customer base and give more partners the tools to build services around our products. The US is an important part of that ambition. Barry brings experience in turning technology into a scalable business, and his advice will help us sharpen our commercial priorities and build the relationships that support sustainable growth.

Barry Flanagan, Non-Executive Director and US Sales Advisor at EfficientEther, said:
EfficientEther addresses problems that customers already need to solve, from managing Microsoft cloud costs to getting applications ready for migration. That gives us a clear starting point for growth. I look forward to working with Ryan and the board to develop the US opportunity and help partners build a compelling business around the portfolio.
