Your current tools

All relationships equal

Manual data entry

Lots of poor connections

at your service


You can access your company’s rich database after just one central email sync, and it will stay updated forever.


Algorithms process the duration, consistency, reaction speed and volume of a user's correspondence to give accurate insights into relationships.


Index automatically pulls in information from email metadata and public websites, so there's no need to enter data manually.

Index maps your company's network in real time

See your company's network grow as it happens, without any manual data entry. Our system continually updates to include new reachable contacts and reevaluate existing relationships.
