Bio

Welcome to my profile 🎊 I'm amazed how mentoring has helped me advance my career and would love to help you work through startup growth or personal development challenges. I started out in strategy and communications before moving into startups in 2019. I led the product-growth relationship at what3words, analysing AB tests using SQL & DataStudio and teaching teams about experimentation. I then moved into a pre-seed sex therapy app called Ferly, where I started the growth process, monetised the product and ran growth marketing channels. That led me to my latest role at series A startup Peanut. As Product Growth lead, I worked across monetisation, activation and retention. I'm now a growth consultant helping early stage startups grow their mobile app and web presence 🌱 You can find me writing on Medium for UX Collective & Bootcamp: https://medium.com/@rosiehoggmascall Past talks and podcasts: - Monetising subscriptions - App Promotion Summit - Appy Hour Podcast - App Growth Summit
