Boomrang

What Boomrang does

Boomrang is a consumer mobile application that enables prank phone calls, operated by Impulz Technologies and founded around 2020 by Tjerk Wolterink in Utrecht, Netherlands. The app lets users place recorded or AI-driven prank calls, with audio content supplied through voice actors and an expanding layer of generative features including an Autopilot mode (audio listening and response), an AI voice changer, and AI-generated prank scripts. Distribution is via the Apple App Store and Google Play, with telephony delivered through Twilio, payments processed via Stripe and Google, and the marketing site showing a catalogue of user-submitted "Top Calls."

The business model is consumer-facing and usage-based: users access the app freemium-style and purchase credits to place prank calls, with small per-call fees driving a low-average-revenue-per-user monetisation structure. The company has integrated multiple third-party infrastructure providers (Twilio for voice/SMS, Apple and Google for distribution, Stripe for payments) but discloses no funding rounds, suggesting a bootstrapped operating posture.

Headcount is reported at 1-10 employees, consistent with a small team led by its founder. User-engagement indicators are modest — 100,000+ total calls and a public Top Calls feed dominated by recordings roughly a year old — and the company maintains geographic restrictions in multiple US states due to regulatory constraints on automated/prank calling. No financial, growth, or hiring metrics have been publicly disclosed.

Revenue model

1. Prank Call Credits: Users pay per prank call using credits. Phone calls cost money to send, so a small fee is charged for every prank call. First-time users receive free credits. Users can also earn free credits by referring friends.
2. Love Calls: Revenue generated from connecting lovers through phone calls using the same credit-based system.
