Paula Bria

Paula Bria

Especialista en Business Intelligence con enfoque estratégico. Conecto datos, psicología y storytelling para impulsar decisiones que generen impactos positivos.

Soy Licenciada en Psicología y Magíster en Psicodiagnóstico y Evaluación Psicológica (UBA). Comencé investigando variables emocionales y cognitivas, hasta que decidí traducir ese pensamiento analítico al mundo del análisis de datos.

Trabajo con lo que hay. Optimizo procesos. Profesionalizo reportes. Ordeno el caos. Y convierto intuiciones en métricas accionables. He creado y desarrollado sectores desde cero, instalando cultura data-driven en organizaciones que no siempre contaban con grandes presupuestos, pero sí con desafíos complejos.

Además, soy creadora y host de “La Cocina del Dato”, un espacio donde entrevisto a referentes tecnológicos desde una mirada humana, demostrando que la cultura de datos también se construye desde la comunicación, la comunidad y la creatividad.

Mi motor es claro: abrir puertas. Mostrar que el mundo de los datos no es exclusivo ni inaccesible. Y ayudar a que más personas se animen a dar el salto.

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.
