Slack Marketplace onboarding that assumes install before account
Design the post-install path for people who click Add to Slack before they have an account with your service, so discovery does not dead-end at the OAuth screen.
Why this can grow a startup
Marketplace traffic is impatient. Slack's own direct-install guidance points out the obvious failure mode: anyone with a Slack workspace can install the app from the listing, including people who have never created an account with the underlying service. If the product treats that as an edge case, the install feels broken. If the onboarding flow expects it, the listing becomes a cleaner acquisition surface because curiosity can turn into setup instead of confusion.
Company example
Slack's Marketplace guidelines say direct install can shorten the distance from discovery to install, but require onboarding that can guide a user to create a new account or connect an existing account when the Slack app depends on a third-party service.

When to use it
Use this when Marketplaces, Onboarding, Product is relevant to marketplace conversion, slack apps, onboarding and you can run a bounded test with a low budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
Founder checklist
- Read Slack Developer Docs: Slack Marketplace app guidelines and requirements and identify what is directly supported.
- Choose one channel context: Marketplaces, Onboarding, Product.
- Define the test around Slack requires the direct-install URL to redirect into OAuth and explicitly warns that installers may not already have an account with the underlying service..
- Set an owner, evidence window, and stop condition before launch.
