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.
Source guidance
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.

How to do it
- Choose one target segment and define the exact next action this tactic should prompt.
- Adapt the tactic to Marketplaces and Onboarding, using evidence from Slack Developer Docs: Slack Marketplace app guidelines and requirements as context—not as a promised result.
- Record a baseline for: Share of target users completing the product's first-value action. Set a guardrail that would make you pause the test.
- Run a narrow pilot and choose a test window that fits the normal decision or use cycle; do not scale before you have observed the full cycle.
- Compare the signal with its baseline. Scale only if the intended action improves without crossing the guardrail; otherwise revise one variable or stop and record what you learned.
