Central Hub. Sphere helps you manage and grow your real estate business. Sphere was designed by top agents. It gets rid of the post-it notes, whiteboards and spreadsheets and tracks of everything in one place - every aspect of all transactions, To Do lists, contacts, deadlines, doc archive, and much more. It is easily accessible to anyone with a Sphere account from any device (laptop, phone, tablet). 20% More Sales. The average Sphere user sales increased by over 20% in the first 12 months. Top users exceed 100%. A solid system for managing your business results in higher closure rates and creates more time to pursue new sales (as well as more free time). Business Plan. In just a couple of minutes, Sphere creates an annual business plan tailored to your business. It then generates a daily dashboard and monthly reports to keep you up to date on your progress. To help hit sales targets it creates a daily lead generation contact list and makes it easy to see whether you are hitting your referral goals. Gmail & Outlook. Sphere syncs with Google and Outlook calendars so every date and deadline from open houses to house anniversaries are always with you. It also syncs and organizes Gmail and Outlook emails so you always have a searchable list of all conversations with each client. Coaching. Sphere highlights important action steps each day for sales growth. It provides monthly ideas for ways to engage your sphere. It creates birthday and housiversary notifications, as well as detailed monthly and annual business reports with metrics on progress toward goals, opportunities for growth, and best practice tips. Teams. Sphere recently rolled out functionality for teams. Different roles have different privileges and access to different data and functionality. Team leaders have access to a dashboard with performance metrics on each team member as well as the team as a whole. Organization is even more important for teams and a collaborative platform is essential. TCs. Sphere will shortly roll out Transaction Coordinator functionality we believe will be the best TC software on the market and will allows TCs to easily be included in any agents transaction. Full CRM. Including functionality that automatically finds and integrates your contacts’ social media accounts so you always have current details and easy insight into what’s new in their lives (e.g. “Wow, Jessica Lee just had twins. I wonder if they need a new place.”) Email Marketing. Sphere makes it easy to send email blast or newsletters to clients (similar to MailChimp). External Services. Sphere already integrates a service that provides realtor supplies (branded signs, hats, shoe covers) for which we receive a percentage of sales. We plan to add additional services in the future. Sticky. Most agents who try it even very briefly feel it's a really valuable tool. Our conversion and retention rates have been far higher than we’d thought was possible. More than 90% of agents enter a goal or a single transaction convert from trial to premium users. Free for New Agents. Sphere is free for any new agent (licensed in the last 12 months) until they hit $2M in transactions. We hope by providing Sphere we’ll meaningfully increase new agents chances of becoming successful and they stick with us once they are.
