About Hotzapp
A CRM built by people who sell on WhatsApp every day. So you can serve more customers without working longer hours.
Hotzapp is a CRM that lives inside WhatsApp Web: quick messages, kanban and scheduled messages, in the same tab where you already talk to customers. Founded in 2017 in Brazil by Guilherme Rangel (PhD, Technical University of Berlin, Germany) and Eneida Pereira. The extension has over 2,500 users and a 4.7 rating on the Chrome Web Store.

Our story
In 2017, Guilherme built Hotzapp to recover lost sales over WhatsApp instead of email. It took off.
If you sell on WhatsApp, you spend all day in chats: explaining the payment options one more time, figuring out who's just asking and who's ready to buy, juggling the schedule. And more people keep coming in. The chat that went quiet sinks down the list, and you lose track of who you still need to get back to.
In 2025, with ad costs climbing, we saw you could sell a lot more to the people already messaging you on WhatsApp. So Hotzapp started looking at your whole workday, not just at recovering one sale. And every tool that promised to help made you leave WhatsApp and retype everything somewhere else.
That's how Hotzapp became what it is today: a CRM that stays in the same tab as WhatsApp. You reply with one click, move the customer to the next stage without leaving the chat, and the follow-up goes out at the time you set, even while you're in another tab. The result: you serve a lot more customers in a day, without working longer hours.
Hotzapp is for people who handle their customers themselves: clinics, stores, consultants, real estate agents, course creators, media buyers. People who sell one-on-one and can't leave anyone waiting for a reply.
