To model Viral Cycle Time’s effect on growth, I searched the web, high and low, looking for a pre-defined formula. To my great surprise, there was no formula that I could find that correctly calculated customer growth, and showed the impact of Viral Cycle Time. What was also surprising, was that I did find several blogs showing formulae for viral growth, but in every case, they appeared to make the same mistake, which was assuming that the entire customer base would continue sending out invitations for every cycle. So I collaborated with my partner, Stan Reiss, who turns out to be a whole lot smarter than I am, and he helped me develop the fomulae that are used in the more sophisticated model for viral growth below:
There’s a second downside to this model. Although I’ve done advertising and sponsorships in the past, and have made hundreds of thousands of dollars doing so, the truth is it takes a lot of time for this business model to start to generate income for you, because you need to build that audience first. In addition, what happens when you build your audience on a platform that ends up changing its algorithm, affecting how often you actually get seen by the audience you’ve built?

Peerstreet – This residual income option is slightly different, helping you earn money using real estate backed loans instead of the property itself. By helping fund the loan, you’ll earn a percentage of the interest rate charged to the borrower. Most loans are short-term, generally lasting between 6 and 24 months. You can build your own portfolio by choosing the exact loans you’d like to fund, or Peerstreet will choose the loans for you. Again, you need to be an accredited investor, although the minimum investment here is just $1,000.
Viral marketing or viral advertising is a business strategy that uses existing social networks to promote a product. Its name refers to how consumers spread information about a product with other people in their social networks, much in the same way that a virus spreads from one person to another.[1] It can be delivered by word of mouth or enhanced by the network effects of the Internet and mobile networks.[2]
