If you're confident in your team's ability to create a valuable product, then funding is just one way of many to grow. Your goal should always be sustainability, so ask yourself what it will take to get there. If the answer isn't an investment, it doesn't mean all hope is lost!  Other businesses often use crowdfunding sites like Indiegogo or Kickstarter for jumpstarting their business. And don't forget about small loans - if you have good credit, banks are good places to go for little startup loans that can make all the difference between success and failure when starting out!
