Digital products
Sell once, deliver forever: ebooks, courses, templates, software.
Digital products are the highest-margin passive income asset class accessible to anyone with niche expertise. Make once, sell forever. Zero marginal cost per sale. The platform (Gumroad, Lemon Squeezy, Amazon KDP) handles checkout, delivery, and payment — you keep 90%+.
The catch: discovery. Without an audience, even excellent products sit unseen. The pillar covers the audience-product sequence, niche selection, and the catalog effect that compounds across multiple products.

The lowest-friction way to sell something online — but the friction-free part is also why most Gumroad stores never make $100/month.
Selling Notion templates on Gumroad
Build a small library of vertical-specific Notion templates and sell them on Gumroad — realistic $200-2K/mo within a year for operators who pick a niche and ship steadily.
