The Swedish caller ID and blocking service Truecaller, which has proven particularly big in India, has been around since 2009. However, the company’s growth has been particularly impressive of late.
Back in January we reported that Truecaller had amassed 10 million users. On Wednesday, the firm said it had hit 20 million – that’s twice as many users in just under 5 months.
Truecaller is effectively a huge, international reverse-lookup phone directory. Its data is derived from official phonebook services and also from users’ personal phonebooks, and is generally used to combat spam callers and telemarketers.
