Chris Huntingford

Chris Huntingford

Hi there, I’m Chris!

I'm a seasoned tech leader, keynote speaker, and technology consultant with expertise across the full tech stack, from enterprise architecture and data platforms to advanced AI (including Agentic AI and Responsible AI / Trustworthy AI). I’ve led large-scale, high-value enterprise projects and initiatives across industries (with a strong focus on government), helping organizations harness emerging technology responsibly to solve real-world challenges - I try to remove the fluff and cut to solving the real problem.

My style is bold, straight-talking, and deeply authentic. I'm a natural connector who brings people together to spark collaboration and creativity. A lifelong tinkerer and excessively curious, I thrive on exploring new ideas and building communities around innovation. I encourage teams to think differently, color outside the lines, and always remember to stay human in a tech-driven world.

As an international keynote speaker, I've energized audiences with talks on AI, Ethics in Tech, data strategy, and true concepts around digital transformation, infusing humor and real-talk into every session. Whether I'm advising C-suite leaders on AI strategy or coaching teams on the latest tech, my goal is to inspire innovation, enable people to do awesome things and drive positive change. If you're on the verge of the next big breakthrough and need a dynamic speaker or consultant, let's connect. I'm all about helping to #BuildAwesomeThings and making sure we all #StayExtraHuman along the way.

Infrastructure Engineer during the day, tinkerer during the night!
When I'm not pushing code or fixing servers, you can find me trying to automate anything that moves (or doesn't move - I'm not picky). I'm a firm believer in the power of memes, using duct tape to fix just about anything, and the occasional brainstorming session with my sidekick rubber duck (who is a great listener, by the way).

Since joining Microsoft in 2018 through the FSLogix acquisition, I’ve been deeply involved in shaping Windows 365 and its community—starting from its earliest days as a Visio stencil. I’ve contributed to key innovations like Windows 365 Boot, Switch, and the Windows 365 app, and helped incubate the vision behind Windows 365 Link. My mission is to drive innovation across Windows 365, AI, Windows, and Microsoft Intune, while empowering customers through community and technical enablement.

I’m the author of five books, including the newly released Mastering Windows 365, and am currently working on Mastering Microsoft Intune – 2nd Edition, a follow-up to the 20k+ bestseller. I hold seven patents across cloud and virtualization technologies and have won six internal Microsoft Hackathons.

Before Microsoft, I was a Global Black Belt for Azure Virtual Desktop and have been recognized with community honors including Microsoft MVP, Citrix CTP, VMware vExpert, Parallels VIPP and Nvidia NEPA—an achievement held by only five people globally before I joined Microsoft.

I also co-lead the #DAASLIKEAPRO community survey, founded the Microsoft meets Community: Windows 365 event (aka.ms/w365event), and host the Windows in the Cloud video podcast (aka.ms/WindowsintheCloud). I regularly speak at global conferences like Microsoft Ignite, Citrix Synergy, VMworld, and more.

Please note that Sessionize is not responsible for the accuracy or validity of the data provided by speakers.

Most Active Speakers 2025

Every year, we put together a list of the most active speakers. This list features the top 3% of speakers who have participated in events using Sessionize during the 2025.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2025. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 39,000 unique accepted speakers this year, the 3% is 1163. Not all of them have their speaker profiles set as public, and we respect that, so the list doesn't show all of them.

The calculation is based on the number of accepted events, that's the main criteria, but to get more refined results we also look at things like multiple sessions per event, sharing a session with a co-speaker and how big the event is. Number of submissions and declined sessions don't affect the list.

Please note that the count of events and sessions in this list does not represent the number of events and sessions from the year 2025. Instead, it shows the number of events and sessions featured on the speaker's public speaker profile; these numbers have nothing to do with the award itself.
