Sweet tactics, very useful, but I disagree completely with the headline for one reason: growth is necessary for success, but not sufficient. Growth doesn't happen without something really great. You can optimize growth techniques in the ways described above when you've iterated on your product enough to already be facing diminishing returns from pure feature-building. Or shit, maybe sooner.

I think of time spent on product as establishing the curve you'll follow: if you're building intelligently, it makes the company and the product more valuable to do more product-building. But time spent on growth can only move you along the curve faster.
