Founder & CEO
Data Scientist

Mike Zawitkowski

Mike Zawitkowski is a full stack data scientist with experience solving big data and machine learning problems since 1999—before “big data” and “machine learning” were trendy.

In 2016 Mike founded Acorn Analytics and has since led the team to strategically guide organizations towards more data-driven approaches. Past clients include software companies, startups, other consulting firms, and publicly traded companies in the Fortune 100. Mike and Acorn’s work has converted petabytes of data into millions of dollars of value.

Mike dreams of one day having alpacas (and one guard llama) on his property.

Liz Mitnick

Liz, who has been part of the Acorn team since early 2019, earned her B.A. from Washington University in St. Louis, followed by a Ph.D. in Earth Science from the University of California – Berkeley. During her academic tenure, she gained experience in analytics, data visualization, and programming.

After earning her degrees, Liz pivoted from academia to the tech universe, taking her analytical science training and putting it to work as a data-whisperer. Not only does she excel at finding nuggets of insight amid messy datasets, Liz is also expert at communicating findings to her clients – making sure recommendations are actionable, concrete, and of course – backed by data. 

In her spare time, Liz enjoys making free-form art, writing, practicing yoga, and hanging out with her cool neighbors in Haight-Ashbury.

Amber Bruce

At her last company Amber was involved in the creating incentive programs for customers, telling the company origin story in a podcast, and developed/co-lead their culture hack program for employee-driven initiatives.
She holds a bachelor’s degree in English Literature. She’s used this skill to create project roadmaps and presentation decks. Her early “career” started as a live-in volunteer with an intentional community in the remote forests of Oregon. There she learned conflict resolution, committee management, and the value of hard labor tending her farm and 80 acres of forest.
She’s most excited to be part of a company whose values are beneficial to the LGBTQ community and her lifelong home in the SF Bay Area.
