funding Starting a new business is typically demanding, especially raising the necessary amount of startup capital to get your dreams off the ground and running. Usually startup entrepreneurs secure funds from family, friends and mostly from their own funds when they bootstrap. Angel investment is a common second round of financing for start-ups. Venture capitalists are approached for larger funds.
