Kim Berg

Kim Berg

I started my career in a service desk role, which quickly sparked my interest in how technology is built, operated, and scaled. From there, I moved into data center hosting where I gained a solid understanding of infrastructure, reliability, and what it takes to keep critical environments running. I don’t have any formal education in IT, but I’ve always been a lifelong learner who grows through curiosity, hands‑on experience, and a drive to constantly improve.

Almost a decade ago, I discovered my passion for the cloud and specialized in Microsoft Azure. Since then, I’ve focused on modern Ops, platform engineering, and enabling teams by taking ideas from early concepts into secure, scalable, production‑ready solutions. Over the years, I’ve expanded my expertise across data, AI, and IoT and IIoT, and I most often work with clients in the role of Solution Architect, helping them design and build practical, outcome‑focused architectures tailored to real enterprise needs.

I’ve worked across a wide range of domains including defense, public sector, manufacturing, and energy, which has shaped how I approach architecture, security, and complex enterprise environments. I also contribute to the open‑source initiative Enterprise Scale AI Factory and enjoy collaborating with others to advance how we build and deliver modern solutions.

🗣 Sharing knowledge is a big part of who I am. I’m passionate about public speaking and mentoring, and I enjoy helping others grow by making technology more accessible and actionable.

Today, I work with enterprise‑scale AI, data, and IIoT solutions with large companies in Sweden, turning ideas into real, measurable impact.

As Principal AI Product Manager at Microsoft, my focus is on helping customers reimagine what’s possible with Cloud, AI, and virtualization technologies, as we move “From a computer on every desk in every home, to a PC in the Cloud on any device and AI in every service”.

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.

Sander Hoogendoorn

Sander Hoogendoorn

Sander Hoogendoorn is an independent dad, avid traveler, and lifelong software developer. With over 40 years of hands-on coding experience under his belt, he still ships code every day — because once a developer, always a developer.

Currently the CTO at iBOOD, Sander has led technology at companies such as ANVA, Quby, and Klaverblad, and was once Capgemini’s global agile thought leader. But don’t expect corporate buzzwords — Sander’s known for cutting through the fluff with a post-agile mindset and a healthy disregard for outdated best practices.

He helps teams and organizations break rules that need breaking — replacing heavyweight processes with lightweight thinking, and agile dogma with actual flow. If something’s slowing your team down, chances are he’s already ranted about it in a keynote.

Onstage, Sander brings code, stories, and sharp insights — whether he’s talking disruption, continuous delivery, microservices, monads (yes, really), software architecture, or the lost art of elegant code. His talks are fast-paced, thought-provoking, and never just theory.

Sander believes in small steps, critical thinking, and building stuff that works. No silver bullets. Just better software, made by better teams.

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.
