What are some creative ways to generate more leads for business?

I found out that building free tools to generate leads for my business recently took off. But building normally is time consuming, so I have one of my engineering team members build a no-code tool first, and then we launch and test it out. If it works, we program the tool with more customization and enhanced quality.
