The 600 million numbers that Truecaller has in its directory have been collected via crowd-sourcing. Truecaller’s users can share their contacts and in return they get access to search in the collaborative database. Thanks to this collaborative data solution, the directory is growing and being updated continuously. It also contains numbers that no other directories have, e.g. pre-paid phones.
Sustaining an effective engagement campaign can take a surprising amount of work. You could limit yourself to following the leads from the data you collect, but following without interacting first will get you a very low follow-back ratio. More importantly, if you follow and then forget people, they may follow back, but they’ll soon forget you. A high number of followers who don’t reply to, mention or retweet your account are of no value. True engagement is long-term and repetitive.
