Close.io is a CRM focused on sales, designed originally as an in-house tool for Steli Efti and his crew at Elastic Sales. Sick of doubling your work by contacting people via email or on the phone, then going back and logging it in the system later? Close.io, among other things, reduces that workload by tracking communications via close.io. Spend more time pursuing and closing your leads and less time doing data entry.
