About Jesse Mostipak
My career has made sense to exactly one person: me.

The short version
I started as a high school science teacher, became a data scientist, moved into developer relations, and ended up running growth. From the outside it looks like four careers. From the inside it’s one job: figure out what people need to understand, then make the right answer easy to find and easy to trust.
That used to mean a classroom. Now it means engineers, buyers, and the AI systems they ask for answers. I bring a data scientist’s habit of checking the numbers and a teacher’s habit of explaining them, and I build things so they keep running after I hand them off.
The route here
01 · Teaching
High school science in New York City. Built a curriculum from five years of Regents exams, and passing rates went up 42%.
02 · Data science
Predictive models for esports, program evaluation for a 25,000-member Girl Scout council, and the reporting that kept grants funded.
03 · Developer relations
Kaggle, Posit, and Baseten. YouTube programs, a 2,500-person virtual conference built in two weeks, and a certificate now past 3.3 million enrollments.
04 · Growth
Search, AI visibility, email, analytics, and paid media, now as Director of Growth at Voxel51.
Also
I co-wrote Data Science in Education Using R (Routledge, 2020), and I founded the R for Data Science Online Learning Community, which grew into one of the largest R learning communities online. When members wanted to lead, I coached them to build and run their own programs, including a reading group, a mentorship program, and a YouTube channel.
I studied biochemistry at Northland College, earned an MA in secondary science education at Hunter College, and was an Agency Fellow with Harvard’s Strategic Data Project.
I take on a few projects a year for small businesses and nonprofits. Here’s what that looks like.
