Andrew Mao is a founder-led CEO and product-focused technologist with 13 years of experience building personalized learning products and machine learning systems. He co-founded Parsnip, a gamified cooking-learning app with a 4.9⭐ rating and notable early backers from Duolingo and culinary circles, blending education science with consumer product design. Previously he architected scalable, personalized time-series ML platforms and productized momentary-event EMG detection at CTRL-labs, bringing both research rigor and hands-on engineering to hardware-adjacent ML. His background spans academic research (PhD level) and industry experimentation—he shipped open-source research tools and contributed bug fixes and docs to the well-known Meteor JavaScript platform. Comfortable switching between code, experiments, and go-to-market execution, he has a rare mix of teaching-oriented product vision and deep technical fluency. An avowed learner and cook, he applies the same research mindset to designing systems that help others learn faster.
