looking for any advice/recommendations on extending a product to tap into larger audiences via integrations/add-ons on marketplaces, specifically in the SaaS B2B context. Salesforce’s AppExchange and Atlassian’s Marketplace are probably the biggest examples with the most proof/info on revenue. Slack is probably another, but folks fully monetizing on it seems a bit early (?) Basically: What are some best practices to size the market opportunity in joining the “fray” in these marketplace communities? Beyond Atlassian and Salesforce, are there any other large, “proven” (in terms of revenue) marketplaces for B2B apps?
