Danny Postma built HeadshotPro — an AI headshot generator — to $300,000 per month in revenue while working solo from Bali. No employees. No investors. No office. Just one developer, AI APIs, and a problem everyone has: the need for professional headshots without the hassle and cost of a photographer.
The Business Model
HeadshotPro solves a specific, expensive problem. A professional headshot session costs $150-500 and requires scheduling a photographer, traveling to a studio, and waiting days for edited photos. HeadshotPro charges $29-59 per person, delivers results in 2 hours, and requires only uploading selfies.
How it works:
- Customer uploads 8-12 casual selfies
- AI trains a model on the customer's face (takes ~30 minutes)
- AI generates 120+ professional headshots in different styles, outfits, and backgrounds
- Customer downloads their favorites
The economics:
- Customer pays: $29-59
- AI compute cost: ~$2-5 per customer
- Gross margin: 85-95%
- At $300K/month revenue with 90% margins = ~$270K/month profit
Why It Works
Universal demand. Everyone needs a professional headshot — for LinkedIn, corporate websites, resumes, and social media. The total addressable market is hundreds of millions of professionals worldwide.
Price disruption. $29 vs $200+ for a photographer. 10x cheaper makes it an impulse buy rather than a considered purchase.
B2B expansion. Companies buy team packages for all employees. One corporate deal can be $5,000-50,000. This is where the real scale comes from.
Viral mechanics. People share their AI headshots on social media. Every share is free marketing. LinkedIn posts showing "AI vs real headshot" comparisons go viral regularly.
The Solo Founder Playbook
Danny Postma is a serial solo builder. Before HeadshotPro, he built and sold multiple smaller AI products. His approach:
- Find a specific pain point that AI can solve 10x cheaper than the current solution
- Build fast — ship an MVP in weeks, not months
- Price for volume — $29-59 makes it accessible to everyone
- Automate everything — AI handles the product, Stripe handles payments, email handles support
- Stay solo — no employees means near-100% margins
What Solopreneurs Can Learn
HeadshotPro proves a specific formula: take expensive human service → replace with AI → charge 10% of the original price → serve 100x more customers.
Other opportunities following the same pattern:
| Human Service | Cost | AI Version | AI Price |
|---|---|---|---|
| Professional headshot | $200-500 | AI headshot | $29-59 |
| Logo design | $500-2,000 | AI logo | $29-99 |
| Product photography | $50-200/image | AI product shots | $5-15/image |
| Resume writing | $200-500 | AI resume | $19-49 |
| Voice acting | $500-5,000 | AI voice | $5-50 |
Each of these can be built by a solo founder with existing AI tools (Stable Diffusion, Flux, ElevenLabs) and standard web infrastructure.
What the $300K Proves
$300K/month. Solo. No employees, no investors. HeadshotPro proves a simple thesis: find something expensive that AI can do cheaply, then charge 10% of the original price to 100x more customers. The APIs exist. The infrastructure is commodity. The demand is very real. The only thing missing is someone willing to build the product.
