"No Man's Land" is traditionally known as the area between two trenches. This is a reference to World War I and the vicious trench warfare and hand-to-hand combat that characterized that war. In "No Man's Land" lay a wasteland of dead bodies and other debris and shrapnel. Increasingly, I am seeing many startups who were ably seed funded get caught in "No Man's Land" between the seed round and a true Series A round led by a venture capitalist.
This is happening because there are way too many companies raising seed capital but not enough executing their way to a Series A. This can happen for many reasons including not raising enough capital in the seed round to begin with and of course not getting your product out the door.
