>If they can, corp dev people like to turn the tables on you. They like to get you to the point where you're trying to convince them to buy instead of them trying to convince you to sell. I worked for an established company (not a startup) and had a run in with Wal-Mart.

Sometimes it isn't about the "big sale" but having the big company on your list of customers. It can give your company a lot of credibility.
In fact, if you have 100 customers on your books then it’s likely that customer number 101 has heard of many of them even if the regular guy on the street has not.
That one big customer - especially if it’s an early one - can really screw up your relationships with the customers that actually spend money with you - and what happens to your credibility when they quit?
