Letter from Vik Paruchuri

I am excited to announce some updates on our leadership team with the addition of Celeste Grupman, CEO, Anna Pershyna, CTO, and Casey Bates, Technical Program Director. In the next year, Dataquest will expand its course offerings with a focus on AI literacy, add new assessment features, and continue  its mission to provide the best resources to learn data and technical skills online.

I started Dataquest to help anyone learn data science and programming the way I did – through hands-on projects and challenges. I led Dataquest for eight years, and we helped more than 1M students reach their goals. I’m excited for Celeste, Anna, Casey and the rest of our team to continue our mission and reach the next million.

While I have stepped away from working on Dataquest full time, I will continue as the Chairman of the Board, close advisor, and content contributor as I pursue working on AI research projects like Marker and Surya.

Keep learning,

Vik
