The idea of value-added investors is pretty silly IMO. On one side, you add value to your team not by investing but by hiring. On the other side, you never want to have to rely on investment and with interest rates as low as they are, loans would almost always be preferable over equity dilution.
Usually the most significant value an investor can add is by making a raise as fast and painless as possible so the founders can get back to building their business. "Smart money" and "value-added" seem like concepts invented by investors to get equity at a better price. Founders should desire to spend as little time possible networking with investors and the maximum time focused on building products, engaging with customers and networking within the industry.
