DoubleTick.io's answer:
DoubleTick.io was founded by Deepak Bhagchandani in 2021, born from a recognition of the growing use of WhatsApp by businesses for customer communication and commerce. He noticed that while many businesses relied heavily on WhatsApp, they lacked tailored solutions that fully utilized its potential. Thus, QuickSell, and later DoubleTick, were developed to provide robust mobile technology solutions that transform how businesses engage, retain, and monetize their customer base using WhatsApp.
