Truecaller is a Sweden-based reverse-lookup phone directory service that has around 45 million users. Truecaller has raised $18.8 million in funding led by Sequoia Capital. The company has partnerships with Yelp and Twitter.
The partnership with Yelp entails these features: When you get a call from a restaurant, you will see what restaurant it is and Yelp will show ratings and pictures of it.
Truecaller started around two years ago and has grown to 35 employees. The company is expecting to hit 60 employees by the end of the year.
Truecaller said that they make it easier to identify spam callers and they maintain a crowdsourced database of marketers. Truecaller can also be used for searching names and phone numbers to see who they are assigned to. Users can also upload their phone contacts to help the community identify callers.
