This week, I caught up with a founder from SF. He’s building an AI-based solution in the HR space. Several ideas he’s tried haven’t worked, but this one is gaining traction rapidly. He told me his failures made him reflect; he wondered what he was doing wrong compared to other founders.

He asked one of his old professors (he has a graduate degree in computer engineering from an Ivy League school) why he’s having a much harder time than his peers getting enterprise companies to try his solutions. The professor didn’t mince words; he told the founder he wasn’t leveraging his network. He was reaching out to large companies cold and getting the door slammed in his face left and right. No one would listen.

Armed with this new idea, the founder leveraged his school’s network to get warm intros. The results have been drastically different. Large companies are not only excitedly listening to his pitch, they’re trying his product as early users.

I asked the founder what his takeaway is from all this. He said he believes that getting decision-makers in large companies to try technology from start-ups requires warm intros, and to get warm intros you need a strong brand name or a good network.

If you’re a founder thinking about selling to a large company, consider who in your network can make a warm intro to decision-makers. If the answer is no one, ask yourself what you can do to build your network.
