Firstly, you have to understand that for investors "money" is a product. They are also in a business. They invest money so they can make more money from the venture in the future.

Tech startups often offer the kind of reward that investors look for. You have to really prove that investing in your company will make them money in the future- that will make the deal a lot more attractive for them.

Also, there are many programs offered by government, banks, other organizations for funding small businesses. Connect with your local chamber of commerce and other business organizations in your area who may be helpful.

If you are confident in your venture then funding it via debt is not a bad option, most small businesses are funded this way.

The other way to try is crowdfunding.
