Some products require scale or critical mass before they can be profitable. This is especially true for many website based on advertising models. Also ventures based around getting big partnerships (e.g. licensing deals) may require the prestige of VC backing before you can get through the door.
Secondly you might have an option of growing organically for 3 years and hoping that no one else enters the market and that its still buoyant in that time or growing fast with VC support. I am not saying it's not possible to grow fast without VCs but I am sure it helps. I think it just comes down to what business it is.
