What do we do?

Close.io allows startups to close more deals and make more sales. It's a sales platform with fully integrated VoIP calling and two-way email communication that syncs with your existing mailbox. Salespeople can spend more time communicating with their customers and less time on data entry because all activities are automatically tracked.

Why join us?

1) Profit is the best form of capital to raise.

2) Remote and travel friendly. Want to work from Berlin or Singapore or Bali or a month? Go for it!

3) We value elegant, novel approaches to all problems whether it's how to present customers with a mobile experience without being a standalone app on their homescreen to finding RFC-compliant hacks to uniquely identify and track emails opens and clicks per user.
