Teasha Feldman-Fitzthum from Commonwealth Fusion Systems
For the thirty third episode of One the Come Up, I was honored to be joined by Teasha Feldman-Fitzhum. Feldman-Fitzthum’s career began at MIT as a physics major. Originally intending to pursue graduate school, she pivoted to entrepreneurship after enrolling in MIT’s 13.366 entrepreneurship class, where she and her cofounder successfully launched EverVest. Originally known as Cardinal Winds, and a company a little bit beyond my understanding to explain, EverVest used copula modeling to predict wind in order to calculate the revenue of future wind farms, and was acquired by UltraCapital in 2016. Currently, Feldman-Fitzthum works at Commonwealth Fusion Systems, the largest fusion energy company in the world, in technoeconomics – yes autocorrect, that is a word, it is just a new field. Ms Feldman-Fitzthum, your course can’t come soon enough.
Also on this podcast, perhaps my favorite piece of advice that I’ve learned so far: you just need to increase your luck surface area! The crux of the lesson, put yourself out there and good things will (hopefully) happen.
