LEAD IN is a home-buyer app: search for projects, chat with the sales team and book a site visit, all in one place. For property developers, sales teams receive messages from Messenger, Instagram, LINE and in-app chat in a single back office. Built by BuildSphere.

From the first message to the site visit, your sales team keeps every conversation in one place.

For sales teams and project owners
Sales teams use the BuildSphere back office to receive customer messages from the app and from connected channels such as Facebook Messenger, Instagram, LINE and TikTok (where supported by the platform) in one inbox, manage leads, reply to chats and follow up on project visits. Administrators authorize each channel connection themselves and can disconnect at any time.
