I have walked this trail before. More than once.
I have been building and running businesses for about twenty years, usually four or five at a time, with a real estate and investment portfolio running underneath all of it. A wedding venue. A floral company I started with my sister and later sold. A bartending company, and a handful of others. Some of them worked. Some I walked away from. A couple I shut down on purpose, and one or two simply failed. All of it counts, and the ones that did not make it taught me at least as much as the ones that did.
So when you are deep in it, chances are I have been deep in something like it. The month that does not math out, the partnership going sideways, the call you keep not making. That is familiar ground for me, not a case study. Through all of it I have kept the friendships and the partnerships, which I care about more than any of the wins. But the real reason to bring me in is not the list. It is that I am good at one specific thing. Walking with someone through the long middle of building something, and not leaving until it can stand without me. That is what I would do with you.
