Welcome to the second episode of Sunlight Matters. In this episode, we explore the fascinating connection between real estate, artificial intelligence, and the importance of sunlight with Giulio, the founder of Masterkey. Masterkey is revolutionizing the home buying experience by giving buyers the tools to make more informed decisions through AI-powered property analysis.

One of the most exciting features of Masterkey is its integration of sunlight mapping, a game-changer for anyone looking to understand how natural light affects a home. Sunlight plays a crucial role in real estate, influencing everything from property values to daily comfort and even well-being. In cities like New York where high-rise buildings cast long shadows, knowing how much sunlight a property gets can make all the difference.

In this conversation, we dive into how AI is helping home buyers analyze properties more efficiently, why sunlight is a key factor in making a smart investment, and how tools like ShadowMap provide valuable insight into a home’s exposure to natural light.
