Every day, we receive calls from unknown numbers, with no clue who’s calling or why. This disrupts our work, invades our personal lives, and raises fears of falling victim to fraud.

The rise in spam calls and scams has led many of us to ignore calls from unknown numbers. Unfortunately, this means we often miss important calls that genuinely require our attention—whether from a recruiter, government office, doctor, childcare, delivery service, or even a friend whose number we haven’t saved.

Koll’s mission is to bring phone calls into the modern age, removing the insecurity and discomfort that comes with them. With the Koll calling app, you'll always know who is calling and for what reason. You'll never again receive a call from an unknown number.

Koll is launching a revolutionary app that solves the problems associated with phone numbers and the safety of calls. Instead of dialing phone numbers, the Koll app connects you to verified people and businesses. Phone numbers will lose meaning and disappear.

Our vision is that within a few years, the world will switch to making calls through the Koll network—just like it shifted from SMS to WhatsApp a decade ago. The word "call" will be replaced by "koll."

Now, you have the chance to be a pioneer in this transformation. Download the free Koll app from the App Store or Google Play and join us in new era of communication.
