Where it sits in the data

Boomrang's $1.6K a month is higher than 47% of the 6,604 projects with founder-reported monthly revenue in our dataset; the median across them is $2K. Snapshot: 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

My view is that demand is specific: the buyer is someone who wants to prank a friend by phone. Distribution would need an app-install surface, free credits, and a free first call, while the product would need usable scenarios, responsive conversations, and recordings that can be shared.

The hard parts are handling calls and recordings, maintaining reliability, managing user support, addressing regulation around prank calls, and competing for attention. Those requirements make this more involved than a basic app that only makes a fixed call.

Verdict: Needs real work.

One thing to take from it

A focused app can present a simple activity through a short product flow: choose a prank, send the call, then get the recording. Boomrang’s visible offer combines that flow with free credits, a free first call, AI responses, and shareable recordings.
