Natacha Fourmy

Qui suis-je? 🤔
Imaginez un chef d’orchestre, mais au lieu de baguettes, j'utilise des post-it colorés et des stylos à paillettes. Je suis Natacha, Scrum Master, passionnée par la magie de la collaboration et l’art du développement agile.

Ma Philosophie 🌱
1. Transparence Totale: Comme une fenêtre sans rideaux, j'aspire à une communication claire et honnête.
2. Collaboration Joyeuse: Travailler ensemble, c'est un peu comme une danse. Parfois, on se marche sur les pieds, mais on finit toujours par trouver le rythme parfait.
3. Amélioration Continue: Le Kaizen est mon mantra. Je crois que même les meilleures pratiques peuvent toujours être affinées.

Anecdotes & Talents Cachés 🎭
• J'ai une collection de stylos de tableau blanc. On ne sait jamais quand on aura besoin d'inspiration arc-en-ciel!
• Mon superpouvoir? Je peux détecter un blocage de projet à des kilomètres, un peu comme un chien de chasse flairant une piste.

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.
