A guy sees a girl. At the first sight, he immediately falls in love with her – he even thinks he might be able to build a life with her.
He thinks “one day I’ll show up in front of her, and I’ll make sure she gets totally impressed.”
He gets into a hard training mode. He works out. He trains on talking skills. Basically he works hard to improve on what he thinks she will love about. All these, while she has absolutely no clue about even his existence.
One day, he finally meets her, then goes from 0 to 100 just like that – “Hi, I love you so much, I am very great in many different ways. Can you please consider marrying me? I really need to get married by (date), because my time is running out.”
It’s a pretty absurd story. But this is kind of similar to how some founders approach fundraising. They want to build metrics until the last minute. This is psychologically understandable – investors want to see metrics. But investors are generally not ready to throw money at someone they met for the first time, who nonstop brags about their company’s accomplishments without much listening, while having only 4 weeks of runway left.
