AI Stock Photo Marketplace

The idea

A marketplace for AI-generated stock photos where buyers get unique, royalty-free images and prompt-engineers earn per download.

Verdict: PASS 28/100

The unit economics are fundamentally broken: AI image generation has near-zero marginal cost, so per-download payouts collapse toward $0.01–$0.05 per image. Prompt engineers have no scarcity, no lock-in, and can generate thousands of images in hours—volume races to the bottom instantly. Incumbents (Shutterstock, Adobe Stock) already integrate DALL-E and Midjourney; Pexels and Unsplash offer free alternatives. You cannot win on supply or demand.

Tribe

Graphic designers, marketers, and small business owners seeking cheap stock imagery; aspiring 'prompt engineers' looking for passive income.

Pain level: low

Stock imagery is already abundant, cheap, and legal. Designers do not wake up in pain over stock photo sourcing. Prompt engineers are not a real tribe—they're hobbyists attracted by the illusion of passive income, not professionals with recurring revenue models.

Market size

TAM: ~$3.5B global stock imagery market (Shutterstock, Getty, Adobe combined ~$1.2B annual revenue). But AI commoditizes this: the TAM is shrinking, not growing, as free tools proliferate.

Year-1 SOM: Realistically $0–$50K year 1. You have no distribution advantage, no exclusive supply, and no pricing power. Even 10K downloads at $0.03/image = $300 revenue.

Strengths

Risks

Competitors

Moat

None yet. You have no exclusive supply (prompt engineers sell everywhere), no network effects (buyers go where the images are cheapest/best), and no pricing power (AI commoditizes production). Incumbents can copy your model in a sprint.

5 actions for this week

  1. Validate the core assumption: ask 5 graphic designers and 5 marketers if they would pay for AI stock images vs. generating their own with ChatGPT + Midjourney for $10/month. If >4 say 'generate myself,' kill this.
  2. Model the math: calculate break-even payout per image needed to attract 100 prompt engineers uploading 10 images/week for 3 months. Then calculate the price per download needed to cover that cost + platform margin. If the result is >$0.50/image, the model is dead.
  3. Research Etsy's AI image category: pull 50 AI image listings, note the sell-through rate and seller sentiment. If <10% of listings sell >5 times/month, demand signal is weak.
  4. Interview 3 active prompt engineers: ask how many platforms they upload to, what payout they need to make it worth their time, and whether they'd commit exclusively. If the answer is 'I upload everywhere' and '<$1 per image isn't worth it,' you have a supply problem.
  5. Spend 2 hours using DALL-E, Midjourney, and Pexels API to generate and license 50 test images yourself. Understand the true cost and time. This will reveal whether the arbitrage is real or illusory.

Kill criteria

Kill this idea if (1) >80% of designers and marketers you interview say they generate their own images or use free tools; or (2) your unit economics model shows the payout per image must be >$0.25 to attract supply but buyers will not pay >$0.50 per image (negative margin). If either is true after 10 conversations, the business model is structurally broken.
