Integration Platforms are third-party tools that sit between your SaaS and other apps. Sometimes referred to as "middleware," they facilitate data and workflow integrations, and sometimes allow for multi-step processes. Zapier, Workato, and Microsoft Flow are example integration platforms. Learn more.
Marketplace Apps are direct integrations between your app and another partnering SaaS. Left Hook will build your app and list it your partner's marketplace (aka "App Store" or "Directory"). Any configuration screens are branded and highly customized to fit your mutual use cases. Example marketplaces include the Salesforce App Exchange, G Suite Marketplace, and Hubspot App Marketplace.
