Can you start a business without a capital? Well, of course you can start a business without capital, you can do this by using ecommerce marketplaces or social media sites. If you want to start a business with zero investment you can use Amazon, eBay, Facebook Marketplace, facebook shop, Instagram Shop, etc. However, just because you have started a business without any investment does not mean you will be able to succeed, you will have to invest in paid marketing to generate sales. There are of course business ideas where you do not have to spend money on products, but if you want to sell your products, you still need money.
