Before looking externally, you should establish if there are funds which could be released internally to assist growth. Sources include:
Use Spare Cash
If you have surplus money in your business bank account not required for the day to day running of the business, use it for expansion - it's cheaper than keeping it and borrowing money.
Perform an analysis of where you spend money and then consider how to cut costs. Think about:
Offer share options
You may want to take on employees who you feel could accelerate growth. They may work for reduced pay in exchange for the option to buy an equity stake in the business at a fixed price at some point in the future. This keeps staff motivated to achieve targets whilst cutting the wage bill for the business.
Sell assets you no longer need
Consider if anything could be sold for cash such as property that’s not providing a great return or inefficient or underused equipment or stock.
