Joy Curtis

Joy Curtis

Joy Marie Curtis started her career as a Kindergarten teacher. Today, she is a Senior Project Manager implementing AI solutions for governments, hospitals, insurance companies, and beyond.

If you think that’s a jump from Kindergarten to Senior Project Manager, think again—because good project management should be as simple as the ABCs.

Joy currently runs the NeuralSeek Internship Program, where she mentors emerging talent and helps bridge the gap between theoretical AI knowledge and real-world implementation. Through this work, she focuses on building practical skills, ethical awareness, and delivery discipline in the next generation of AI professionals.

Joy believes too many AI companies overcomplicate implementation. Her approach is to simplify the landscape by guiding organizations through metacognitive strategies—thinking about how we think about AI—to get back to the fundamentals of what AI is, what it is not, and how it can create measurable impact.

She is not afraid to highlight both her project successes and failures, because her ultimate goal is to move AI from the imaginary into real-world impact.

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.
