Fabien Billiet Vandeschrick

Passionné d'histoire, de culture agile, de jeux, de science fiction et de généalogie, j'aime m'inspirer de ce que j'observe et de mes rencontres.
Agiliste convaincu, je ne considère pas l'agilité comme une finalité, mais comme un levier pour révéler le potentiel d'une organisation. Mon rôle est donc d'accompagner les équipes dans leur quête d'efficacité, de collaboration ou de sens. Qu'il s'agisse de concevoir des produits, relever des défis organisationnels ou renforcer une dynamique collective, je m'engage à construire des solutions durables.

Josh Ether

Josh Ether

For the past 15 years, I have been an integral part of many successful organizations due to my experience and dedication. My coaching and consulting has allowed clients to achieve excellence as well as exceed their goals. It has been a privilege to be associated with such great achievements.

My Human Centered based methods have been proven to be successful, having been applied in a variety of projects with resounding results. My approach is comprehensive, taking into consideration all contributing factors to obtain the desired outcomes for clients that provide real value.

I'm passionate about empowering individuals and systems to identify and tackle the obstacles they face on their journey to success. Building trust within their systems through means of inspection, experimentation, and adaption we revise collaboration, & communication. I'm committed to helping my clients achieve long-term results. My ultimate goal is to support them in C.E.C. so that they can make lasting progress in life.

Collaboration is critical for the success of any solution. Working with a diverse group of people helps produce more effective results, and that's why I always strive to create an atmosphere where such collaboration can take place. By leveraging the skillsets of different individuals, we can develop high-quality solutions in a timely manner.

Experimentation is an invaluable tool in finding suitable solutions. To approach a problem in an effective manner, it's important to look beyond the traditional methods and explore something new. This might include using different techniques or tools to test out potential ideas and uncover the best solution. Experimentation gives us a chance to discover and try something that could potentially be groundbreaking, so it shouldn't be overlooked when dealing with complex problems.

Trust is essential for any team or organization to be successful. This confidence is established through effective communication and how information is shared. It's important to understand the power of these interactions, as they can create a feeling of reliability that allows everyone in the group to collaborate confidently.

The challenge organization’s face today is how to sustainably provide for the needs of growth while simultaneously protecting what has been built. A balanced approach is needed, one that combines sustainability with modern innovations. We must build a foundation for future prosperity that takes into account the needs of the organization, individual and the consumer.

Please note that Sessionize is not responsible for the accuracy or validity of the data provided by speakers.

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.
