I Make $15K/Month From One Website

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.

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.
