# I Make $15K/Month From One Website Source: https://www.youtube.com/watch?v=qIlX7cQ2UdU Recap page: https://rapidrecap.app/video/qIlX7cQ2UdU Generated: 2026-03-01T18:33:56.155+00:00 --- ## Quick Overview Maddox successfully built and sold his unblocked games website, DuckMath LLC, for $120,000 after achieving $15,000 MRR by consistently posting high-volume, data-informed TikTok content across multiple accounts and cross-posting to Instagram Reels and YouTube Shorts. **Key Points:** - Maddox built DuckMath LLC, an unblocked games website, which reached $15,000 in Monthly Recurring Revenue (MRR) before he sold it. - The primary growth driver was a high-volume TikTok strategy: posting 3 times a day across 3 TikTok accounts, 5 days a week. - The tech stack for the site was kept lean and utilized free or cheap services: Cloudflare for hosting, Supabase for backend/auth ($20/month tier), and Posthog for analytics (free tier). - Maddox initially copied the top-performing videos of his competitors on TikTok, analyzing hooks, pacing, and tone to guide his own content creation. - His best-performing video garnered 2.1 million views on TikTok and led to significant traffic spikes, resulting in a peak daily AdSense earning of $240. - He sold DuckMath LLC in late 2025 for $120,000 via Escrow.com, a figure he initially felt was low but later regretted not holding out for more. - His core advice is to focus on growth over building a 'serious' business initially, emphasizing consistency (getting 1% better daily) and rigorous content analysis. ![Screenshot at 00:02: A graphic showing Maddox's initial passive income of $517 over two years, contrasted with the $12,931 he made while taking action, illustrating the shift from inaction to growth.](https://ss.rapidrecap.app/screens/qIlX7cQ2UdU/00-00-02.jpg) **Context:** The video features an interview between Pat Walls of Starter Story and Maddox Schmidlkofer, a college student who successfully built and sold a profitable unblocked games website called DuckMath. Maddox details his journey from sitting idle for two years to implementing a highly effective organic short-form video marketing strategy, primarily on TikTok, which scaled his site to $15K MRR and led to a six-figure acquisition. ## Detailed Analysis Maddox Schmidlkofer built DuckMath, an unblocked games website, starting from a period of two years where he did nothing, leading to minimal earnings ($517). Upon seeing a younger creator succeed with a similar concept on TikTok, he decided to aggressively market his site. His strategy centered on creating massive amounts of short-form video content (3 videos/day across 3 TikTok accounts, 5 days a week) cross-posted to Instagram Reels and YouTube Shorts, using repurpose.io to automate this. He focused on analyzing and copying the formats, hooks, and pacing of his competitors' most viral videos, which led to massive traffic spikes—one video hit 2.1 million views on TikTok alone, resulting in a peak daily AdSense earning of $240. The tech stack was intentionally lean and cost-effective, using Cloudflare for free hosting, Supabase ($20/month) for backend and authentication (handling user data like leaderboards and coins), and Posthog (free tier) for analytics. He made crucial AB tests to maximize time-on-site and page clicks, which directly impacts AdSense revenue. After achieving $15,000 MRR, he sold DuckMath LLC for $120,000 via Escrow.com, a figure he now somewhat regrets not pushing higher, but he considers the process of growing the site through consistent, data-driven content his most important lesson. ### Initial Struggle & Inspiration - Sat idle for 2 years earning only $517 - Inspired by a younger creator on TikTok making unblocked games sites look easy - Decided to start marketing daily. ### Cracking Distribution (TikTok Focus) - Used 3 TikTok accounts, posting 3x/day, 5 days/week - Cross-posted to Instagram Reels and YouTube Shorts using repurpose.io ($30/month) - This high volume led to millions of views, including one video hitting 2.1M views. ### Business Breakdown & Tech Stack - Website hosted on Cloudflare (Free) - Backend/Auth using Supabase ($20/month) for user data (leaderboards, coins) - Analytics managed via Posthog (Free tier) - Monetized primarily through Google AdSense. ### Growth Strategy - Analyzed and copied top-performing viral videos in the niche (hooks, pacing, action) - Focused on keeping users on site longer (A/B testing CTR and time on site) - Peak daily AdSense earnings reached $240. ### Sale and Future - Sold DuckMath LLC for $120,000 via Escrow.com - Regrets not holding out longer for a higher price - Maddox's next venture is a cloud gaming platform called MaddoxCloud, focusing on mobile games via the cloud. ![Screenshot at 00:00: Maddox discussing the initial two years of inactivity before finding success.](https://ss.rapidrecap.app/screens/qIlX7cQ2UdU/00-00-00.jpg) ![Screenshot at 00:04: Maddox Schmidlkofer, the founder of DuckMath, shown in an interview setting.](https://ss.rapidrecap.app/screens/qIlX7cQ2UdU/00-00-04.jpg) ![Screenshot at 00:06: A visual representation of the DuckMath website interface filled with various unblocked games, indicating the product Maddox created.](https://ss.rapidrecap.app/screens/qIlX7cQ2UdU/00-00-06.jpg) ![Screenshot at 00:24: The Escrow.com confirmation screen showing the sale of DuckMath LLC for $120,000.](https://ss.rapidrecap.app/screens/qIlX7cQ2UdU/00-00-24.jpg) ![Screenshot at 01:01: A graph showing the AdSense revenue history, highlighting a massive spike in earnings corresponding with the successful TikTok strategy.](https://ss.rapidrecap.app/screens/qIlX7cQ2UdU/00-01-01.jpg)
