ZUNY FESTER
Biomedical engineer from Universidad de los Andes turned tech corporate girl.
By day I'm Head of Operations & Marketing at Loopfour.ai.
The rest of the time I help businesses adopt new tech and AI,
and I tutor when I can.
I trained as a biomedical engineer at Universidad de los Andes and found my place inside startups: the part where ambiguity has to turn into process, a message, a team that ships.
Today I run operations and marketing at a YC-backed fintech, build websites and apps for brands through my studio, and tutor on the side. I write about tech, women in tech, startups and life in my 20s.
