Adsly

Adsly is a sponsorship directory for anything with an audience: SaaS products, AI tools, newsletters, blogs, podcasts and communities. Problem: selling sponsorships usually means an ad network taking a large cut, or cold-emailing brands one by one. On Adsly creators list their ad slots with their own prices (CPM, CPC or flat rate) and brands contact them directly through a built-in inbox. No commission on deals. Brands browse 23 niche categories and filter by audience, language, ad type and price. There is also a free sponsorship rate calculator and advertising rates by niche. Built solo with Elixir and Phoenix, PostgreSQL and Tailwind.
