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.

Company 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 and metric

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.

Founder checklist

  1. Read GitHub Docs: Displaying a sponsor button in your repository and identify what is directly supported.
  2. Choose one channel context: GitHub, Revenue, Brand.
  3. Define the test around GitHub supports one handle per external funding platform plus up to four custom URLs in FUNDING.yml..
  4. Set an owner, evidence window, and stop condition before launch.
