Some insight I got while working alongside a small app dev-team.
A startup was spending $9,000 on Meta ads. 640 installs. 8 people actually used the app.
That's a 1.25% activation rate.
They didn't have an ads problem. It was their funnel towards the end that was an issue.
So in the end they stopped ads before fixing the main issue.
Three things they were missing that I see constantly with early-stage apps
Fix activation before touching acquisition. If under 20% of installs do the thing your app is supposed to do, no amount of ads or marketing will saves you.
Team sitting on best acquisition channel/s. They had a LinkedIn, a real point of view, and a target customer who's specifically burned out on every other app in the category. "Here's why we built something different" from the actual founder converts better than any ad in a skeptical audience.
Product has shareable output but no content. If your product generates a result a report, a score, a visual , then that's your organic content engine. Design a share moment into it.
Happy to look at anyone's numbers in the comments if you want a second pair of eyes.
