Entrepreneurial Force Multipliers

I was reading an article about technology in the military/police context and the term force multiplier kept being mentioned. Naturally, I thought it was an interesting term in the entrepreneurial/business world. Here is Wikipedia’s entry on force multipliers:

A force multiplier refers to a factor that dramatically increases (hence “multiplies”) the effectiveness of an item or group.

Here are some force multipliers:

• Product development — not one-off features for a specific client but rather opinionated features that fit a focused vision
• Investment capital — particularly when you have the basis for a repeatable sales process that is profitable and/or gains market share
• Search engine optimization — PageRank operates like the Richeter Scale such that each incremental increase results in substantially more credibility

What are the force multipliers in your business?
