68 B2B SaaS marketplaces with opportunities for indie hackers These platforms generally make it easier to find customers, create more focussed products, and build trust. Shopify, Slack, and Salesforce are examples of B2B products with more mature and well known marketplaces, but there are a whole bunch more. They range from more fully featured marketplaces that have integrated user reviews and payment handling, to more basic "integration directories." Out of the 100+ marketplaces and integration directories I found, 68 stood out to me as the ones worth considering as an indie hacker. The ones that have user reviews built in have a (*) next to their names.
