Product Idea
WhatsApp API service for Brazil: Mably Clone - Focus on guaranteed uptime, automatic number rotation, and high-volume message processing (10M+ msgs/month).
Evidence

Mably processes 10M+ messages/month with 99.9% uptime as an official Meta Business Partner. Zero blocking, gradual warming, automatic rotation and 24/7 monitoring. Two products: Mably Cast for campaigns and Mably Hub for customer service. Would love your feedback! +”

Why this opportunity matters
This opportunity surfaced from multi where Growing Brazilian businesses using WhatsApp for customer communication are actively describing the problem in their own words. We classified the demand intensity as high — meaning users are not just complaining, they are openly looking for paid solutions and willing to switch tools to find one. When users self-select to post a problem on a public platform like multi, they are usually already trying to solve it — which makes them strong candidates for the right paid alternative.
How to validate this before you build
Before writing a single line of code, three lightweight steps will tell you whether this opportunity is worth pursuing:
- Read the original conversation. The evidence links above lead to the exact threads where users described this problem in their own words. Read every comment — what people argue about in the replies often matters more than the original post.
- Talk to five real users. Find five people who match the target user description above and ask how they handle this today. You are looking for two signals: a consistent workaround they hate, and a willingness to pay for something better. If both show up in three of five conversations, the demand is real.
- Test willingness to pay before building. Put up a one-page landing site describing the proposed product, with a deposit or pre-order checkout. If even a small fraction of traffic converts to a real payment, you have validated more than most products that ship to production.
