I'm currently building a business plan for my startup. The startup is a kind of Q&A website with an important twist that differs it from existing Q&A websites.
The information in the biz plan spans over 4 years. I suppose to show a reasonable growth rate. I expect the site to be extremely viral and wondering how can I estimate the traffic I'll have in my site, or to be exact the growth rate of the site?
If I'll have to give examples to potential competitors, we have: Yahoo answers, Mahalo.com, Fiverr.com (which is more of a marketplace) and others.
What growth rate will not look ridiculous to investors but still show that the site is going to be a great success?
The growth rate can't be linear of course.
