What has been your most valuable business collaboration?

Hey guys!

Full disclosure: I run/build a platform where we connect SaaS founders and marketers for marketing collaborations and am looking for inspiration for a new feature. 🤫 I'm sure the answers will be helpful for others as well though!

I currently have a fixed "repertoire" of collaboration types I match them based on (guest posts, shared webinars, podcast guest appearances). But I probably don't even cover 1% of what's possible. There are so many more ways in which especially bootstrapping founders can benefit from collaborating with each other. 🤯

So: Have you partnered with another business? What has been the most valuable collaboration so far? What advice would you give to others trying to do the same? 🚀
