Digital Experts Hypotheses

All 18 niches of the Digital Experts hypotheses base with counts (hypotheses, tested, worked) and medians (cost per subscriber, cost per lead, USD) over tested hypotheses. Start here to pick a niche. Data: CC BY 4.0, cite Digital Experts.

Summary of one niche: hypotheses, tested, worked, medians of cost per subscriber and per lead (USD), test budget, years, plus the 10 cheapest-lead tested hypotheses. niche = slug or Russian name (e.g. 'biznes-prodazhi' or 'Бизнес').

Full-text search over hypothesis titles, job stories, offers, creatives and audiences with filters. Returns compact rows (id, title, niche, year, cost per subscriber/lead, verdict, source_url). Use get_hypothesis(id) for the full card. Query in Russian works best (the base is in Russian).
