Monetization

As the former Head of the App Store, I help app-driven businesses grow from initial concept to successful scale. My clients include startups, mid-sized companies, and some of the world's most successful apps.

About me

Successful apps are built on more than great technology. Lasting success requires a clear strategy, a sustainable business model, and effective go-to-market execution.

This is where I help my clients. I combine extensive marketing experience with deep App Store expertise to position products, optimize monetization, and scale businesses for long-term growth.

Depending on the challenge, I collaborate with a trusted network of specialized experts to bring together the right capabilities for each engagement.

Most of my clients work with me over the long term - as a strategic advisor, trusted sounding board, and, when needed, as an interim executive or investor.
