Some years ago, I formed a partnership with Mark Pincus (now Chairman of the game company Zynga) to buy a social networking patent called Six Degrees. About a year after that, I was presented with the extraordinary opportunity to invest in Facebook. My initial response, like that of any intelligent investor, was to make the entire investment personally. But on reflection, I realized that given my relationship with Mark, the right thing to do was to give him the option of taking half of it. Mark and I had no agreement to bring each other any investments. But because of our collaboration on Six Degrees, we were implicitly allied across our shared professional interest in social networking companies. I felt the only honorable thing I could possibly do in that circumstance was to present the opportunity to Mark.
I’ll admit, this wasn’t purely selfless; I was also aware that if I opted not to do so, the deal would create a conflict of interest that could threaten the relationship, as Mark’s interests and my interests in how to deploy the Six Degrees technology might sharply diverge. Mark’s interests could even become fundamentally different from my own, and that would make it difficult to continue working together.
In the end, I communicated to Facebook that we needed to split my portion of the investment with Mark. Yes, I knew that decision would cut the investment’s financial value in half for me, but I also knew the return on the investment of trust and mutual commitment would be infinitely more valuable in the long term. And it was. Later, when Mark formed Zynga, I invested and joined its board; we continue to work together in building huge companies, as deep allies.
