Know exactly where your users come from. From day one.

We built 28 apps before we built Attribr.

And for most of them, we had no idea which marketing channels were actually working.

Downloads were happening. Users were coming in. But the link between "we posted this" and "these people signed up" was always a guess. Gut feel dressed up as strategy.

So we built our own attribution SDK. Lightweight, privacy-first, zero third-party dependencies. Drop it into any iOS or Android app in about 10 minutes and start tracking installs, attribution sources, and 30-day retention from day one.

We've now got it running across the entire MRVL portfolio — 28+ apps, real data, real decisions.

Attribr is what we wished existed when we launched our first app. If you're building mobile products and making marketing decisions based on vibes rather than data — this is for you.
