Small business, not sure who is asking you for that definition. If a large corporation or government have certain amount of business needs to earmark to small business, woman or minority owned business...
You could find definition online, for example SBA. Generally speaking, you are. A company as big as 100M annual revenue, in their eyes are still small business.
