Newsletter platform for niche hobbyists
Substack is a publishing platform. It's not built for the guy writing a weekly newsletter about competitive axe throwing with 400 paying subscribers who needs polls, community threads, back-issue gating, and a merch store integration. Niche hobbyist communities — aquarium keeping, vintage synthesizers, endurance cycling, amateur radio — are monetizing through newsletters but outgrowing generic tools immediately. Grotto is a newsletter platform built for obsessive communities: Discord-style discussion threads nested inside issues, gear recommendation widgets, affiliate link tracking by product category, and subscriber segmentation by skill level. 50 million Americans participate in organized hobby communities. The ones with newsletters have no home-built for them. That's a 0/month problem waiting to be solved.
