Hi, I'm Jyllian. I build products people love to use.
For as long as I can remember, I've wanted to make friends with computers, and to make them friendlier for everyone else. For me, that means getting curious about what people really need, then working with the team to shape it, design it and get it out the door.
Games came first: I founded player research at Harmonix, on Rock Band and Dance Central, and learned how much people care about the things they play with. Since then I've been a researcher, designer, product manager and head of product, often the first product or design person in the room, across healthcare, marketplaces and platforms. I move between industries a lot, because I pick up new things very quickly, and I love the learning. Most recently, at Coviu, our design partners helped us shape an MVP that our small, AI-native team shipped in four months.
