Years ago, when I was trying to sell OneTrueFan to various publishers and promising them a 10% lift in sales, a successful web site CEO I knew gifted me with this very direct feedback:
"Eric, if I took a meeting with every company who emailed promising a 10% increase in revenues, I'd fill my calendar every single week and get no work done. That's just not a meaningful promise to me."
That CEO is now a VC (I'm looking at you, Roy E. Bahat).
Do you think he'd be interested if I pitched him a company that increases its clients' revenues by 10%?
VC (and, frequently, angel) investment is predicated on the idea of disruption -- creating a change in the market that no one can ignore. Be honest with yourself about whether YOUR business is disruptive.
And know that you are far likelier to die wealthy and influential if you just go launch an incrementally better product or service. It's easier and has a far better chance of success. You won't get VC investment, but you can probably launch THAT business without it.
