Peter Ward

Peter Ward

Peter Ward is CEO of SoHo Dragon, a New York–based Microsoft Partner — though he began as a CTO and never entirely stopped behaving like one.

While much of the technology industry focuses on what’s new, Peter is more interested in what works. He has spent years helping organizations implement Microsoft cloud solutions by mastering proven capabilities and executing them without unnecessary drama.

A co-author of four SharePoint books and author of Leadership in a Zoom Economy with Microsoft Teams, Peter continues to contribute to GitHub and remains closely involved in Azure and Microsoft 365 delivery. He has a mild distrust of unnecessary complexity, a preference for projects delivered on time and on budget, and a habit of asking what organisations are really trying to optimize.

He believes most expensive technology mistakes look impressive at the time — and that simplicity is still enterprise IT’s most underused advantage.

Other traits
- Good O365 trainer and motivator
- Good at thinking on my feet in meetings or complex situations
- I find myself often being able to get to the heart of the issue whilst not ruffling too many feathers
- Love yoga, vegetarian food, and reading Malcolm Gladwell books

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.
