What I've Learned Working with 12 Machine Learning Startups

I have worked with 12 startups. They have spanned verticals from fintech and healthcare to ed-tech and biotech, and ranged from pre-seed to post acquisition. My roles have also varied, from deep-in-the-weeds employee #1 to head of data science and strategic advisor. In all of them I worked on interesting machine learning and data science problems. All tried to build great products.
