The text describes a rapidly expanding productivity application that enhances email inbox management and privacy, available on iOS, Android, and through a web interface. In the past year, the app has generated $2.6 million in revenue, with a peak of $211,000 in May 2025. It has consistently achieved over $120,000 in monthly earnings before interest and taxes (EBIT) over the last three months and reached a high in web subscribers. Privacy-conscious users find the app appealing due to its capability to shield inboxes and block emails, with desktop access available via a browser extension. Key performance metrics include 775,000 downloads in the past 12 months, $831,000 in EBIT, and 31,000 monthly active users, with a notable opt-in rate of 37% on iOS. A significant audience segment is represented by three countries accounting for 72% of iOS downloads, and the app achieved a record EBIT of $142,000 in March 2025. Recent revenue growth strategies include a hard paywall on iOS, increasing revenue per user (RPU) by bypassing platform fees, and enhancing web app conversion rates. The early data suggests that the Android hard paywall could generate $1.7 million in a year. The app has also leveraged social media, achieving over 10 million organic views and launching 600 videos. The founders are open to selling the business, as they focus on its initial growth stages and seek flexible offers, including options that allow future involvement. Their lack of marketing expertise presents an opportunity for potential growth through professional marketing efforts.
