At a web services conference a few weeks back, I remarked that the story behind the show was really that fixed costs will become variable / “flexible” costs costs. This is better than capital efficiency, this is capital alchemy. Only allocate capital the instant it can marry customer demand. In the start-up world the trend is hard to ignore.

It used to be that start-up needed $5 million just to build the infrastructure that was needed to launch a website. That’s $5 million just to test whether or not an idea had any legs. That’s $5 million whether just one person who visited your website or millions did. But today, Amazon Web Services has turned this “fixed” infrastructure costs into variable expense. Get your credit card, sign up for an AWS account, and pay as you go. Tough to imagine companies were once launched any other way.

Another example is CPC advertising. It’s only been in the past decade that we’ve seen widespread adoption of pay-for-performance advertising. Instead of doing a fixed $X0,000 media buy, businesses can bid on keywords knowing that they will only pay if someone clicks their ad. A fixed marketing expense is now variable.

Capital alchemy is a trend that has already revolutionized both the advertising worlds and the web infrastructure worlds. Undoubtedly, it will impact many more sectors of the economy. I’d love to meet with entrepreneurs who have some ideas on where the magic of capital alchemy might strike next.
