VCs are the best advertising.

Leaving aside for the moment yesterday advertising and marketing are very different functions (advertising is easy, marketing is hard);

If your target customers are "VC funded companies" then sure, getting in bed with as many VCs as possible is certainly one marketing approach (and probably a good one.)

Certainly you're are a lot of products targeted at businesses who are flush with cash and eager for kit like fancy chairs.

The important part of marketing is knowing who your potential customers are, and the best way for them to get to know you.
