About MUMU Filter

About MUMU Filter

We help businesses verify phone numbers across 60+ social platforms so they can reach real people, not dead ends.

Our Story

MUMU Filter was built by a team who spent years in cross-border e-commerce and data analytics. We saw firsthand how much budget was wasted on invalid phone numbers — messages sent to unregistered accounts, campaigns targeting people who never received them, and marketing teams frustrated by poor results.

We built MUMU Filter to solve this at the source. Instead of buying lists and hoping for the best, our platform lets you verify every single number before you spend a dollar on outreach.

Today, MUMU Filter serves hundreds of businesses worldwide — from e-commerce exporters to online educators to B2B manufacturers — helping them reach real, active users on the platforms that matter.
