Davinder Singh is the founder of Bosun. He builds the product - the WhatsApp assistant, the owner dashboard and the admin - and personally handles setup and support for the businesses that launch on it.

The numbers in these guides come from that work: the measured cost per message, the eight test suites that run against a live instance before every release, and the three defects that only appeared when those suites were run fifteen times in a row.

Task tracking for small teamsWhy job software goes unused, and what has to be true before people keep it current.
WhatsApp Business APITemplates, the 24-hour window, verification, and what it costs to send.
Testing AI featuresWhy a suite that passes once proves little, and how repeated runs surface what a single pass hides.

How these guides are written

Numbers on this site come from running the product - the measured cost per message, the test suites, the security review - or from a named, linked source with the date it was checked. Nothing is presented as a customer result until a real customer has agreed to share it. Read the editorial policy.
