Paul Swider

Paul Swider

30 years building tools that add hours back to a clinician's day
CEO at RealActivity | AI Pioneer | BOSHUG Founder | Microsoft Keynoter

I've spent my career at the intersection of healthcare and technology, not talking about AI transformation, but actually building it. In 2001, I designed a symbolic AI triage engine that eliminated pre-op anesthesia visits and accelerated same-day surgery pathways.

In 2023, my team shipped RealActivity Physician Activity Copilot, the world's first AI harness focused on hospital administration. And 2024, we shipped Wheelhouse, a model fine-tuned on PeopleSoft healthcare operations data and executive prompt workflows.

What happened in between? I trained 3,000+ engineers across GE, IDX, and Microsoft in enterprise software patterns. I migrated 50+ HIPAA workloads to Azure. I built the CMS compliance and activity reporting platforms that health systems still rely on. I earned Microsoft MVP recognition and was named Azure Most Influential, not for evangelism, but for implementation.

Today I'm CEO & Chief AI Officer at RealActivity, a boutique Microsoft partner delivering mission-critical AI for academic medical centers and health systems across the Northeast. Our focus? Tracking system wide clinical time (cFTE), CMS complaint AI, and improving operational efficiency, the problems that keep CMOs and CMIOs up at night. I'm also the founder of OCS Labs, an AI lab building industry-specific AI for government, and sectors where getting it wrong isn't an option.

I founded BOSHUG, the Boston Healthcare Cloud & AI Community, which has grown into a global network serving 40k. I'm a Cloud Wars healthcare AI analyst, a top 3% rated global speaker (Microsoft Ignite, Cloud Wars, and beyond).

Global citizen based in Greater Boston. When I'm not building healthcare AI, you'll find me at a Sicilian bakery arguing about lemon cake, sailing, snowboarding, diving, or planning the next adventure. 114 countries, and counting.

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.
