This is tangential to the core of the article but I can't stress enough how true this is. In the two companies I've co-founded, we've been approached for partnerships by huge companies (Oracle and Adobe) and tiny, 1-person, pre-revenue shops. In almost every instance, it's been a net loss in time and money. The tiny shops just want help making inroads into your industry and customer base. The huge companies just want to show they have "partners" to their direct reports or sales leads. They'll ask you to build out some integrations (on your dime) and scrap the entire project 6 months later (true story). To them, it's a rounding error but to a startup, the financial and opportunity costs can really hurt. There's a reason Gail Goodman calls partnerships a "mirage" [0].
It's great that this call turned into an acquisition for Perfect Audience. I would advise everyone to take Brad's advice: take the call and maybe a meeting–but just one. Unless the meeting goes well and the strategic fit is too obvious to ignore, just say "no" to partnerships.
