Some of the products in my portfolio haven’t launched yet. That’s why I need to keep an eye on where they end up.
Please leave me your name and e-mail, and I will be glad to share with you, how I gain customer insights, how I help teams come up with ideas, how I design and build prototypes and how I validate assumptions.
