    “I had the opportunity to work with Jennifer and Christoph. They came with the right mindset and deeply understood and honed in on specific unmet needs of their target group. They were customer-centric in their approach and while they have a clear big-picture vision,they demonstrated business agility by iterating and pivoting on their concept. They took a 360 view of not only the opportunity but also had an operator-centric mindset to understand the nuances of going to market and making changes as needed to build a product that can potentially scale.
