How do you find sponsors for your website/app?

Hey everyone,

I’m looking for sponsors to help support my project and would love advice from anyone who’s done this before.

I’m building a Chrome extension (https://miromiro.app/) for developers and designers that lets users:

• Extract images, icons, and other assets from any website
• Inspect UI elements and styles directly in the browser

The extension is live and gaining traction:

• ~3,500 installs on the Chrome Web Store
• Last 30 days:
  • 17,769 visitors (+286%)
  • 53,191 page views (+490%)
  • 58% bounce rate (down 12%)

I currently have one sponsor, but I’m not sure what the best approach is to find more:

• Reaching out directly to companies?
• Using sponsor marketplaces?
• Waiting until higher traffic or install numbers?

If you’ve gone through this before, I’d love to hear:

• What worked for you
• What didn’t
• Any mistakes to avoid early on

Thanks in advance, happy to provide more details if it helps 🙏
