You have an edge on the major corporations who have all the money in the world to do traditional advertising, because you know guerrilla. When starting your own business, you may flat out not have enough money to advertise, but you still must market. Marketing is how you are going to sell your amazing product or service, now do it guerrilla-style. When you are starting your adventure as an entrepreneur you don't have a lot of cash flow, but you have a brilliant product or service. You can solve all your marketing problems by taking on a guerrilla technique and have a minimum investment with maximum results.
Because of the state you are in as a new entrepreneur, it is important that you are flexible, yet efficient. This means that you need to be able to adapt to what the consumers want, and how you are going to get it to them. You don't have the money to do it in the ways we know work, so instead you bend the 'rules', do it differently, and get it to them fast.
Overall, it is essential to an entrepreneur to take full advantage of guerrilla marketing. Before you know it, you won't be that small-time entrepreneur with a amazing, unrecognized product... You will be rich, famous, and playing with the big boys.
