$300K/month at peak (reported publicly) → roughly $3.6M annualized. Previous product Headlime sold for $1,000,000.
Started fully solo; now a small team of contractors and part-timers handling support and ops while Danny owns product and growth (per Danny's own interviews)

Timeline
2020-2022Danny builds Headlime — an AI copywriting tool — as a solo indie project from the Netherlands and later Bali. Grows it to meaningful revenue during the early GPT-3 wave.2023Sells Headlime for $1,000,000. Publicly shares the exit and uses it as both capital and credibility for his next product.2023Launches HeadshotPro — AI-generated professional headshots from uploaded selfies. Reaches $100K ARR within 14 days of launch, driven by viral X/Twitter posts.2024Scales HeadshotPro to $300K+/month (approximately $3.6M annualized). Uses a heavily SEO-optimized landing page strategy and affiliate program via Rewardful.2024-2025Affiliate program alone reportedly drives $50K+/month in revenue. Danny continues shipping adjacent AI products (DeepReview, DeepImage) under his Postcrafts holding company.OngoingHeadshotPro remains under Danny's ownership — not acquired. Product continues evolving with new styles, team plans, and enterprise tiers while the core solo-founder architecture persists.Key insights
- 01Selling a product for $1M funds the next one with more leverage. Danny's Headlime exit is the capital and credibility base for HeadshotPro's faster growth curve.
- 02Consumer AI products with a clear 'before/after' demo viralized differently than B2B tools in 2023. Headshots were among the purest examples of this dynamic.
- 03SEO is a compounding moat for solo founders in commoditizing categories. HeadshotPro's landing page strategy ranks for dozens of AI-headshot search terms.
- 04Affiliate programs can be a 30-50% share of a solo-founder business's growth at scale — reportedly $50K/month for HeadshotPro per the Rewardful case study.
- 05Starting in Bali changed the unit economics. Low cost of living meant the first $10K/month was already runway-positive, which is rare for equivalent SF founders.
- 06Product frequency matters less than product fit. Danny ships fewer products than Marc Lou but each hits harder; different solo-founder archetype, same underlying result.
- 07Holding companies (Postcrafts) let a solo founder run multiple products without legal or tax friction, keeping optionality for future exits on individual lines.

What this means for you
- A $1M exit on a solo product is a realistic result, not a dream. Several solo indie founders have now done it publicly — build for it, don't just hope for it.
- Geography matters. Operating from Bali, Lisbon, or Ho Chi Minh City changes the math on how long your solo product can run at break-even before hitting profitability.
- Ride the wave early. Consumer AI had a 'viral headshot' window in 2023 that wouldn't repeat in the same way. Pattern-match the current equivalent window rather than the past one.
- Affiliate programs are undervalued by solo founders. $50K/month from affiliates alone is more than most solo SaaS ever touch on direct marketing.
- Holding company structure pays for itself at portfolio scale. Postcrafts is Danny's vehicle; you want one before you have 3+ products, not after.
- You don't have to stay solo forever to still be a one-person company in spirit. Danny uses contractors where they free up his time — the founder owns product and growth, which are the irreplaceable seats.
