While traditional venture capital companies are larger in size and may provide backing to growing businesses in multiple stages and rounds of financing, angel investors normally solely focus on startup businesses in specific industries, markets, or regions. Angel venture capital firms are usually made up of wealthy individual investors or a network of investors that invest small amounts of early stage capital in startup companies that fit their criteria.
Over the last few years, the amount of angel funding in the United States has closely matched the amount of financing provided by venture capital firms, although it is usually quantified by smaller investments spread across a larger amount of companies. The average amount of angel financing per transaction ranges from $25,000 to $125,000 if it is an individual investor and anywhere up to $2 million or more if it is a group of investors.
