# This simple app makes $250K per month Source: https://www.youtube.com/watch?v=wvYej-2KWDg Recap page: https://rapidrecap.app/video/wvYej-2KWDg Generated: 2025-11-24T18:38:24.265+00:00 --- ## Quick Overview Anton Lebedev's app, Letterly, achieves $250,000 in Monthly Recurring Revenue (MRR) by focusing intensely on user experience, simplicity, and leveraging a validated idea rather than creating something entirely novel, which allowed them to iterate quickly and build a highly usable product. **Key Points:** - Letterly generates $250,000 in Monthly Recurring Revenue (MRR) with 20,000 paid subscribers and 30,000 total monthly active users. - The core strategy for success is built on three pillars: prioritizing user experience, simplifying functionality, and using a proven idea. - Prioritizing user experience (UX) helps onboarding, increases retention, converts more sales, and attracts more users through recommendations. - The app's simplicity is a competitive advantage, allowing users to record speech and get transcribed text instantly, which is easier than typing. - The initial prototype focused on achieving simplicity and usability, which took significant iteration (thousands of hours) before launch. - The tech stack utilizes React Native for the front-end (mobile apps) and Swift/Python for the back-end/web, relying heavily on AI tools like ChatGPT for core functionality. - Anton advises aspiring builders to focus on simple, validated ideas that solve existing problems better, rather than trying to invent something entirely new. ![Screenshot at 00:02: Anton Lebedev introduces himself and states his app, Letterly, makes $250k MRR, immediately establishing the success metric discussed throughout the interview.](https://ss.rapidrecap.app/screens/wvYej-2KWDg/00-00-02.png) **Context:** The video features an interview between Pat Walls of Starter Story and Anton Lebedev, the founder of Letterly, an app that transforms speech into well-written text, primarily emails. Anton discusses his journey, which involved years of failed startup attempts before finding success with Letterly, which now generates substantial monthly revenue. ## Detailed Analysis Anton Lebedev shares the success story of his app, Letterly, which generates $250,000 in MRR from 20,000 paid subscribers and 30,000 total monthly active users. After 15 years of trying and failing to create startups, Anton landed on Letterly, a simple app that converts speech into well-written text for various uses like emails, notes, and meeting takeaways. He explicitly attributes their success to a three-part strategy: prioritizing user experience, simplifying functionality, and using a proven idea instead of inventing something completely novel. Prioritizing UX is shown to directly improve onboarding, retention, sales conversion, and user attraction via word-of-mouth. The simplicity of the app, where users can record and instantly receive transcribed text (which is easier than typing), is a key competitive advantage. The development process involved extensive iteration (thousands of hours) focusing heavily on prototyping and user feedback to ensure simplicity. The tech stack includes React Native for the front-end (mobile apps) and Python for the back-end, heavily utilizing AI tools like ChatGPT for core transcription and rewriting features. Anton's final advice is for new builders to focus on solving existing problems simply and validating their ideas before investing significant time or money, emphasizing that simplicity is often harder to achieve than complexity. ### Introduction and Revenue - Anton is introduced, stating Letterly makes $250k MRR - He spent 15 years building failed apps before Letterly - The app was launched two years ago. ### Letterly's Secret Strategy - 1. Prioritize user experience (Helps onboarding, Increases retention, Converts more sales, Attracts more users) - 2. Simplify the functionality (Free demo without signing up) - 3. Use a proven idea (Not something entirely novel, but something that can be done better than existing options like ChatGPT). ### Focus on Simplicity and UX - The core goal is simplicity and easy user experience, which multiplies the value of every feature - UX is treated as a feature, not an afterthought - Simple onboarding and high retention are direct results of good UX. ### Product Development & Iteration - The first iteration involved prototyping and discussing ideas - They iterated heavily, spending thousands of hours to make the product simple and usable - They aim to simplify the process of starting a recording with a single button. ### Tech Stack - Front-end uses React Native (for iOS/Android) and Swift (for Apple) - Back-end is built with Python - Core functionality relies on AI tools like ChatGPT and OpenAI API. ### Final Advice - Don't spend excessive time and money validating completely new ideas; focus on improving existing, validated concepts simply - If you have a good idea, leave your job and focus 100% on it. ![Screenshot at 00:02: Anton Lebedev states his app makes $250k MRR, highlighting the financial success achieved.](https://ss.rapidrecap.app/screens/wvYej-2KWDg/00-00-02.png) ![Screenshot at 00:08: A slide visually contrasts previous failed attempts \(red 'FAILED' boxes\) with the current successful venture \(green '$$$' box\) on Anton's LinkedIn experience.](https://ss.rapidrecap.app/screens/wvYej-2KWDg/00-00-08.png) ![Screenshot at 00:23: A chart displays Letterly's revenue growth, culminating in $1.1M total revenue, demonstrating scaling success.](https://ss.rapidrecap.app/screens/wvYej-2KWDg/00-00-23.png) ![Screenshot at 04:04: A slide summarizing the three keys to Letterly's success: Simple functionality, Minimal usage friction, and Unique competitive advantage.](https://ss.rapidrecap.app/screens/wvYej-2KWDg/00-04-04.png) ![Screenshot at 11:21: A pie chart illustrating monthly costs and margins, showing Salaries at $30,000, AI Tools at $5,000, and Advertising at $200,000, against the $250,000 MRR.](https://ss.rapidrecap.app/screens/wvYej-2KWDg/00-11-21.png)
