How long will your idea take?

This is a question seed investors should ask.

One did. I was surprised.

I think some ideas will take 7 years to build. Many media ideas can take that long. Bad for seed.

Start with 50k users based on your techcrunch launch and grow at 20% per month. How long before you have $10mm in revenue — assuming growth is amazing the whole way.

Well $10mm revenue is $1 per thousand impressions when you have 10 BILLION impressions per year.

500px the flickrish site is at that level now.

So how long will it take you to get there at 20% per month growth?

5 years.
