Martina Grom

Martina Grom

I’ve spent almost three decades in IT, always drawn to the places where technology can make work better for real people. Long before cloud, governance, and AI became mainstream, I was already exploring how to make these technologies practical, secure, and human‑centric.
As the Principal, Co‑Founder & CEO of atwork, I help organizations modernize how they operate—bringing together Microsoft 365, Azure, security, governance, and AI to create workplaces that are built for the future, not just for today.
I’m a long‑time Microsoft MVP and have been a Microsoft Regional Director since 2015. I also founded the Global AI Community – Vienna Chapter to give people a welcoming, accessible place to learn about AI and experiment with what’s possible.
Sharing knowledge has always been a big part of who I am. Whether I’m consulting, speaking, writing, or building community, I want to empower others to understand technology deeply and use it confidently. I hold a master’s degree in International Business Administration from the University of Vienna—but the real learning has come from helping people navigate change every day.

Most Active Speakers 2023

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 2023.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2023. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 25 thousand unique accepted speakers this year, the 3% is 771. 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 2023. 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.
