GitHub sponsor button on default branch
Add the sponsor button from a default-branch FUNDING.yml so a public repo can turn goodwill into a visible support route instead of a dead-end thank-you.
Why this can grow a startup
Open-source traction often creates a strange gap: the project looks useful, but the visitor cannot tell how to support it, hire around it, or keep the maintainer funded. GitHub's sponsor button makes that path visible right on the repository surface. Even when direct sponsorship is not the main business model, the button signals that the maintainer expects a long relationship with the community and has thought about sustainability. That changes the emotional read of the repo. It stops looking like abandoned freeware and starts looking like maintained infrastructure with a visible support path.
Source-backed example
GitHub Docs says a FUNDING.yml file in the repository's .github folder on the default branch can show GitHub Sponsors, one external funding handle per platform, and up to four custom URLs.
Source-reported evidence
Source: GitHub Docs: Displaying a sponsor button in your repository
GitHub supports one handle per external funding platform plus up to four custom URLs in FUNDING.yml.

When to use it
Use this when GitHub, Revenue, Brand is relevant to maintainer sustainability, trust signal, repo monetization and you can run a bounded test with a free 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.
How to do it
- Choose one target segment and define the exact next action this tactic should prompt.
- Adapt the tactic to GitHub and Revenue, using evidence from GitHub Docs: Displaying a sponsor button in your repository as context—not as a promised result.
- Record a baseline for: Qualified prospects who complete the intended paid 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.
