The Most Profitable Solo Business You've Never Heard Of
2 min read23 Apr 2026Worth watching
TL;DR
Brett, a solo designer from a 500-person Midwest town, built a productized design subscription agency called DesignJoy to $1M/year with no audience, no team, and minimal expenses. The video covers his exact model, pricing evolution, AI tools, and identifies copywriting agencies, AI-first dev agencies, and branding as the next big productized service opportunities.
Key points
1
Brett launched DesignJoy in a weekend via Product Hunt with zero audience, hit $10K recurring revenue day one, and scaled to $80-200K/month net profit while keeping his day job for 4 years
2
Productized services replace traditional agency proposals and calls with a simple subscription: pay, get work delivered fast, pause or cancel anytime - dramatically lowering time-to-value
3
Brett raised prices 8 times (from $449 to $8,000/month) every time demand felt overwhelming, and each increase counterintuitively boosted demand by repositioning him in a premium tier
4
AI has been a net positive for his business: more startups need design than ever, and AI tools like Claude and Midjourney have expanded his own output capacity without hiring
5
Top productized service opportunities identified: AI-first development and deployment agencies ($10-20K/month retainers), branding-only agencies, copywriting subscriptions, short-form video clipping, and YouTube thumbnail design
Actionable insights
→
Launch a productized service on Product Hunt this weekend with a simple Webflow site - no audience needed, just get friends and family to upvote to reach the homepage
→
Use ChatGPT to write your prompts for other AI tools (Midjourney, Runway, NanaBanana Pro) and specify the target tool in your request so it includes correct parameters and style flags
→
Start a recurring-need productized service (thumbnail design, short-form video clipping, podcast editing, copywriting) rather than one-off services to capture durable monthly revenue
Notable quotes
“I held my full-time job until I was making 80,000 a month and then I quit. And I was making 75,000 a year at the other job.”
