There are many different kinds of investment that you might be looking for. I am afraid you will need to provide further details about your startup's niche, your investment goals, etc. before recommending any particular path. There are angel investors, there are VCs, etc. and also incubators / accelerators depending on what your business is and at which stage it is. Be sure to have a well-researched estimate of how much money you need to raise. I would be happy to discuss the possible options for you over a call.
