Definition by the book

Deal flow refers to the rate at which business proposals and investment pitches are being received by venture capitalists, angel investors and private equity investors. 

Rather than a rigid quantitative measure, the rate of deal flow is somewhat qualitative. Deal flow often follows a cyclical pattern as trends unfold in social and economic environments.

What it really means

The number of investment opportunities available at a given time to a particular company or investor or within a particular region or market sector.

In brief, deal flow can be summed up as the funnel of investment opportunities that a company has.
