Qubole Qatalysts
Introducing Qubole Qatalysts
2019 is the inaugural year for a Qubole-focused big data community program called Qubole Qatalysts! Qatalysts are our biggest marketplace champions. They are energized about putting big data into active use. They want to share and collaborate with others in this community. In return, we equip them with a private online community site for sharing, access to technical resources, and a pat on the back for their leadership and active participation.
Qatalysts are nominated for their portrayal of one or more of The Four E’s:
- Expertise – Has achieved a deep big data proficiency and an ability to effectively communicate it to others
- Engagement – Willing to interact with the community-at-large, and in doing so, provides a personal touch
- Educator – Capable communicator who provides opportunities for others to learn about the value of big data applications
- Evangelist – Has experienced success from data activation and is shouting his or her story from the rooftops!
We are proud to announce our charter class of Qatalysts. Will you be next?
