Are you associated with Rightmove at all? I couldn't find an API on their site.

If not, how are you planning on monetizing this? You've got what appears to be quite a large team for a product that mentions nothing on pricing or "how it works".

Design wise, its very clean. I love the colors and the logo. However, the very first screen is part of a trend that really irks me. Why use the entirety of my machine's viewport to show me a screenshot, a couple words, and a CTA to request an invite when I know nothing about the product other than "list properties"? It looks good, don't get me wrong, but I feel there is a missed opportunity to sell.
