How do I convince the parents of my fiance about the success of my potentially risky startup?

Hey guys How do i convince the parents of my fiance about the potential of the startup . i also need to convince my fiance too. Her questions are around the fact that the internet is extremely risky much alike the movie making business ie it is hit driven, I have raised serious vc funding and have done a lot of groundwork for the past 2 years... do give me your idea fellow founders!?

Prove it works. If you're selling something then prove it'll sell.

For the net you have to attract traffic, it's not natural. So how will you attract traffic?

If all else fails you don't have to convince them, but instead prove yourself. If you succeed that's all the proof they'll ever need that you are right.

What kind of business are you starting????????

Wait until you make it financially and you'll be a hero. Then they will be begging you to marry her and so will loads of other women.

It is risky. The only way you can convince them is to be successful! This takes time. Work hard, network, advertise and do what you have to do.

Don't try to convince them of your success, cuz there is no guarantee. (The convincing is for the VC's)
Are you asking them for money ??

Just let them all know that you understand the risks, and there is no guarantee, BUT IF you don't try it, you will regret it forever..

You will survive.... There is no reward without risks..
Good Luck!

PS: Don't forget to remind them how much you love their daughter.
