Too Much Growth Hacking, Not Enough Product
Altman: This is YC's mantra, but it's so important I wanted to talk about it again. The best companies all have great products. Unfortunately, the current fashion in Silicon Valley has gone a little too far from this — it's too much about growth hacking and sales and marketing machines.
That does work for a while. You can actually get away for a pretty long while by executing really well to grow a mediocre product. But you don't usually create a Facebook-sized company by doing that.
You can grow a mediocre product with execution. But you don't create a Facebook-sized company that way.
The Spontaneous Tell-a-Friend Filter
Altman: Here is the very simple framework I use. If I think about all the most successful internet and mobile startups — enterprise and consumer — I heard about those because they were so good that one of my friends spontaneously told me about it.
They were not being incentivized. They didn't market to me. They didn't advertise. It was just — someone I trusted said 'you've got to try this new thing, it's amazing.'
Every great startup: someone you trust spontaneously told you about it. No incentive. No ads.
The Power Law Filter
Altman: If the startup is not going to get there — to the point where people spontaneously tell their friends — I think they will not be at that number one spot on your power law of returns. This is a really important filter.
If people won't spontaneously tell their friends, it won't be the #1 return.
