Lorenzo Barbieri

Lorenzo Barbieri

From the moment I turned on my Vic-20, 40 years ago, I knew my life was aimed at technology. I've always been the first in line to test out new products, services, gadgets, especially those which promised to change people’s lives. I’ve always been a tech superhero.
After all these years, my personal mission went from changing the world through technology to improving the world, one human interaction at a time. Changing the way people live in the digital age is possible only by addressing the human factor, together with technology.
My proven track record of driving sales involves creating connections, building communities, challenging views, delivering value, and going the extra mile.
As a Cloud Architect and Evangelist, I’ve presented technical and business content to a wide range of different audiences, from executive meetings to large developer conferences, including many online and in-person events, and I was recognized as the “best speaker” multiple times, thanks to a clever mix of storytelling and technology.
I have a deep technical knowledge of Application Innovation and Modernization in the Cloud, Cloud Native solutions and, of course, on-premises solutions. I can drive product development and technology teams.
I have a deep business knowledge of Manufacturing, Automotive, and Construction business, coupled with a broad knowledge of ISVs and Microsoft partners.
So, if you're ever in need of an evil genius being able to impact deals through human interactions and technology, look no further. I’m the right person to help with your business!

Rachel Dubois

Rachel Dubois

I believe that we can create products and services that make the world a better place. And that we can learn and grow in the process of doing so. Our challenge is that we waste time and money and human energy on untested ideas that, too often, turn out to be something that the customer does not want. Or, if we have an idea that is really good, we get in our own way by not executing it well, by not being able to communicate, inspire, and empower our collaborators and stakeholders as we must in order to do the impossible: launch and grow good ideas that the world needs, fostering sustainable and ethical growth.

I work to solve that.

Most Active Speakers 2024

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 2024.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2024. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 38,000 unique accepted speakers this year, the 3% is 1036. 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 2024. 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.
