Network Effects And Viral Loops

Network effects and viral loops are the holy grail of growing the user base of an internet service rapidly and cheaply.  I talked a little about network effects in my previous post about using radically reduced pricing to disrupt a market. But in case you missed it, when network effects are present, the value of a product or service increases as more people use it.  Online social networks are a great example; sites like Facebook, Twitter and Google+ become more useful as more users join.  Groupon is an amazing case study of leveraging network effects to get new users to invite everyone they know your website, as the more people they invite, the cheaper the products and services on Groupon become for them and everyone else. The businesses that list their services on Groupon get access to massive amounts of new customers in exchange for offering them volume discounts. In other words, the value of Groupon increases for everyone involved the more people use it.  At SalesCrunch, we tap into network effects by capturing and measuring all the knowledge that is transferred in business meetings across your company.  The more people that have meetings, the more statistically relevant, actionable intelligence we can give them in return.  The graphic below is a perfect example. Because we measure when people are paying attention in meetings that happen on our platform vs. when they are off checking email, for example, we can look at thousands of meetings and tell you the optimal length of a meeting based on how long people tend to pay attention and at which point they tend to drift off.

Viral loops are the self-perpetuating mechanisms that constantly bring new people to your service.  The first well know example is hotmail.  Every hotmail email had “get your free hotmail account” in the signature, which drove millions of new users in a matter of months. Facebook’s photo tagging feature is also a great example.   You upload photos of you and your friends and tag everyone in those photos. Your friends and your friends’ friends get an automatic email from Facebook letting them know they and/or someone they know have been tagged in one of your photos.  That brings them to Facebook too see the photos, which increases the likelihood they will upload their own photos and tag their own friends, which brings those people to Facebook to see photos of themselves and people they know, and so forth and so on.

As you can see from the below diagram, the way this plays out at SalesCrunch is that our users bring lots of attendees to our platform for meetings. Some percentage of those attendees become users and bring even more attendees.  More attendees drives more users, and more users drives more attendees, etc.  Per the above, the more users using the platform the more interesting and statistically relevant the information we can provide you about the effectiveness of your meetings.  That intelligence spurs more enterprises to have more employees host more meetings with more attendees to get better insights and so forth and so on.

In a nut shell, network effects and viral loops can drive massive amounts of users significantly faster and cheaper than any traditional marketing.  The key is to build them into your service from the very beginning, not try to bolt them on after your product is built.
