The challenge
People with a large following get far more messages than they can answer. The product had to turn that attention into paid messages, calls and digital products, and make buying one feel as simple and as safe as sending a text. It had to work on iOS, Android and in any browser, stay fast when traffic spiked, and protect everyone using it from misuse.
What we built
Paid messages with a reply promise
Every paid message comes with a reply window. If it isn't answered in time, the charge is refunded automatically, so nobody pays for silence.
Live voice and video calls, priced per minute
Real-time calls with the price per minute shown up front and a live meter during the call, built on a managed real-time video service so calls hold up on mobile networks.
Digital products
Products that unlock straight after purchase, from a profile link that can be shared anywhere.
Discovery that rewards being active
An explore feed that favours profiles that are active and quick to reply, so people see the ones most likely to answer.
Privacy protection
Protection against screenshots and screen recording in the mobile apps, so conversations stay private.
Trust and safety
Automated checks on profile and product images and on message text, reporting and blocking tools, and a published list of what can't be sold.
One product, three platforms
Native apps for iOS and Android, plus a full web app, so people can use it without installing anything.
How we worked
We designed, built and run it as one team: regular releases across both app stores and the web, monitoring and alerts on calls and messaging, and support tooling for a large, active user base.
The result
Over 200,000 users, a 4.8-star average rating on the App Store, and a platform that held up through sudden traffic spikes when it was featured by major media outlets.
