They loved my concept. Last month, I sent out my finalized business plan to 35 well-known incubators. I've heard nothing from them. There are thousands of reasons plans are rejected and far fewer reasons why they're funded. A smart person with no Internet background will have trouble.
Some incubators specialize by industry.
Others give only certain kinds of assistance. For example, an incubator whose strength is its industry expertise may want only opportunities with a full team of proven managers who lack industry experience. An incubator that takes equity and holds it until IPO or acquisition will want companies with the potential to go public or be acquired. That means a big market size and a fairly early harvest. Since their holding period will be even longer than later investors' holding period, they may need a larger percentage of the company to get a decent return.
