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.

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.
