What DermNet does
DermNet is a New Zealand-registered nonprofit charitable trust (CC50036) that operates one of the world's largest free online dermatology reference platforms at dermnetnz.org. Founded in 1996 by Dr Amanda Oakley alongside a small team of New Zealand dermatologists and supported by the New Zealand Dermatological Society, the platform has grown to cover 2,500+ skin topics with a 25,000+ clinical image library, attracting 20 million annual readers and over 2 million monthly visitors, of whom 63%+ are doctors or healthcare professionals and approximately one in three are repeat users. Content is produced largely on a volunteer basis by dermatologists, dermatology trainees, and medical writers globally, with editorial review by clinicians.
The product portfolio spans the free core reference site (2,400+ SEO-optimized topic pages), the interactive DermDiag skin symptom checker, the DermNet PRO subscription tier for healthcare professionals (currently with a waitlist), a licensable AI training image dataset, a Student Resource Centre, the PO-PASI clinical scoring tool, CPD-certified quizzes, published dermatology books, and translation services. Watermarked clinical images are distributed free under a Creative Commons Attribution-NonCommercial-NoDerivatives license; high-resolution unwatermarked images are sold under quoted one-time commercial licenses. The technology stack is web-based with a custom CMS and image library architecture, and there is no public API or SDK layer.
DermNet's revenue model is diversified across five streams: reader donations (tax-exempt charitable trust accepting multiple currencies via PayPal), corporate sponsorship from pharmaceutical, skincare, and device companies, commercial clinical image licensing, Amazon Affiliate commissions on book sales, and clearly segregated display advertising. There are no outside investors, no funding rounds, and no parent company. The team numbers 11-50 staff based in New Zealand, with operational backup from a global volunteer contributor network.
