I want to start a company by financing. If they find a venture capital company, is the success rate great?

It depends on your own project. Venture capital companies are generally more optimistic about high-tech innovation projects with market prospects. You can try to write a business plan and a project analysis book. If you want to find venture capital, you can go to the investment and financing section, which contains a lot of high-quality venture capital company information that should be useful to you.
