I'm an early-stage VC and a photographer. If you liked this post, please subscribe to this blog and follow me on Twitter @tdavidson. Entrepreneurs, create financial projections in minutes by downloading your next financial model.

Recently I created a short financial model for a friend to help him understand how his newest startup “works” and estimate the basic operational and financial metrics behind his business.

After we went over the basic information about the product and business (a standard part of my initial data request before creating a startup financial model), I realized the crucial part in creating the financial model was going to be understanding the customer acquisition and engagement cycle. I started digging into viral marketing, viral loops and viral expansion loops to understand how to translate people’s behavior and usage of his product into a series of assumptions and equations.

Even though the estimates will undoubtedly be wrong, breaking down the operations into a series of equations forces one to take a very tactical look at product development choices and business strategies.

Maybe someday I’ll release a version of my viral loop customer acquisition and engagement model. Until then, I figured it might be valuable to share a bit of the research I found most interesting and valuable.

Yes, there are a lot of links to Andrew Chen, and as you read you’ll figure out why…

  • Andrew Chen, What’s your viral loop? Understanding the engine of adoption: A viral loop is…

    …The steps a user goes through between entering the site to inviting the next set of new users.

    … Ultimately, viral loops are like induction proofs in that you are jumping to a steady state situation in which your viral widgets/emails/messages are already out there, and you are optimizing some set of steps that users have to jump through. Then, once you get this right, then you are figuring out how to build “on-ramps” into your viral loop so that you bootstrap the entire process.

  • Fast Company, Ning’s Infinite Ambition:

    “Incorporating virality into the functionality of the product.”
    Ning grows because each new user begets more users. Every time someone sets up a social network, he has no choice but to invite friends, family, colleagues, and like-minded strangers to sign on as well. The company calculates that each person signed up for a Ning group is worth, on average, 2 people, compounded daily: On day two, that individual brings in 4 group members and on day three, 8; within a week, she has brought in 128 people. Which is how Ning has been able to grow at a daily average of more than .4% and add 500 new groups a day, doubling roughly every 137 days.

    … “double viral loop,” which spreads two ways, because every network creator is a user and any user can become a network creator.

  • Andrew Chen: Viral marketing is not a marketing strategy:

    Viral marketing is not a marketing strategy
    Successful viral products don’t have viral marketing bolted on once the product has been developed. It’s not a marketing strategy. Instead, it’s designed into the product from the very beginning as part of the fundamental architecture of the experience.

    Viral marketing is not a product feature
    No single feature determines the virality of the product – instead, it’s part of a viral loop that connects a disparate set of functions into a cohesive motivation for the user to tell their friends. If the fundamental product doesn’t drive a viral motivation from its users, then it’s very hard to force it.

    Viral marketing is a fundamental product design discipline
    Instead of:

    We have product X, how do we virally spread it?

    … we ask:

    We have viral loop X, what’s the right product to put into it?

    The skillset for effective viral marketing
    Because of the above issues, “viral marketing” is not really something that ought to be in the domain of soft-skill folks like PR, advertising, and marketing people. Nor is it in the world of hardcore technical folks that can architect systems but not consumer interactions.

    Instead, it’s something that needs to bridge both soft and hard skills. You need an interesting combination of skills, including:

    1. Understanding the motivations behind user behaviors
    2. Understanding and exploiting the technical loopholes to create viral loops

    I think that the fundamental compartmentalization of these two skillsets is what ultimately drives huge companies being worse at viral products than startups.

  • Eric Ries, Engagement loops: beyond viral:

    On synthetic notifications:

    The most blunt instrument is to simply reach out and contact your customers on a regular basis. …true ROI of a synthetic notification has to balance ROI, customer fatigue, and the engagement effects of the campaign itself.

    On organic notifications:

    … the mechanics of sending users notifications when new friends of theirs join the site is a great organic re-engagement tactic. From the point of view of the existing customer, it goes beyond reminding them that the site exists; it also provides social validation of their choice to become a member in the first place.

    The ultimate form of engagement is when the company doesn’t have to do anything explicit to make it happen

    Connecting engagement and viral loops:

    The two loops are intimately connected, in a figure-eight pattern. Customers exit the viral loop and become part of the engagement loop. As your engagement improves, it becomes easier and easier to get customers to reenter the viral loop process and bring even more friends in. And as in all dynamic systems, there’s no way to optimize a sub-part without sub-optimizing the whole. If you’re focused on viral loops without measuring the effect of your changes on other parts of your business (of which engagement is just one), you’re at risk of missing the truly big opportunities.

  • Todd Stephens, Viral Expansion Loop.
  • Tony Wright, Value or Viral?

    It’s easier to build a great business on top of an existing viral engine than it is to build virality into an existing business”
    At the time, I found myself nodding. … It turns out that viral loops are HARD.

    But, as I think about it, I can name something that’s a LOT harder, and that’s building a product that people really want.

  • Andrew Chen: Freemium business model case study: AdultFriendFinder ARPU, churn, and conversion rates:

    * Visitors -> Members: 6-15%
    * Members -> Subs: 10-22%
    * Subs -> Renewing Sub: ~80%
    * Revenue per member: $0.48-$0.95

And most recently, the latest from Andrew Chen on Freemium models, How to create a profitable Freemium startup (spreadsheet model included!). Worth a deep look…

    QUESTION—Incorporating viral loop-like expansion strategy into a consumer product:
    Is it possible?
    What are the possibilities? I am looking to launch a consumer product, but there really needs to be something unique that will help drive its growth. Any ideas???

  • http://www.unstructuredventures.com/uv Taylor Davidson

    I always have ideas :)

    Of course it's possible, it just depends on the product, the customers, the market and your business. The key is to make virality a fundamental component of the product and the value proposition.

    Drop me a line with details and I'll see if I can come up with some ideas; or comment and see if the “community” can create some ideas…

    Taylor and “community- I appreciate any input that you can give.
    The consumer product is all-natural granola. Granola sales have seen very good growth in the last several years and big players have stepped in to capture market share. I propose following a Jones Soda-like strategy and basically “giving” the brand over to the consumers. I would like to solicit and then put 4-6 customer photos on the label along with their name, hobby/passion and social network affiliation. In this way, like-minded consumers can connect with one another thru our granola brand. The profiles would continuously alternate over time to maintain fresh faces. I think that this gives us a unique look and strategy to differentiate the brand in the market. It is clearly an alternative brand concept and the marketing strategy is unlike anything the other companies are doing.

    Granola has a tree hugger/hippie connotation to it. I think that there is an opportunity to position the brand differently. However, other than simply putting up a website for users to visit, I am having difficulty incorporating a viral-loop element to the concept. It is difficult already, but being a consumer product makes it even more so.
    Thoughts? Ideas Anyone?

    Thanks!

    Darren: I don't quite understand: why do you think it is difficult to incorporate a viral-loop element into a consumer product? What do you mean by a “consumer product”? Most viral loop strategies play on basic consumer psyche and can apply in any setting or environment where people share ideas about products.

    The web didn't create viral loops; the web just created entirely new ways to apply the psychology with a completely different set of customer acquisition tactics under a very different cost structure. The fundamental psychology behind viral loops applies online and offline.

    Taylor–
    I understood the concept to be fairly new and that it mainly applied to web-based properties (social-networks, etc…). I have heard that Tupperware, Avon and direct-sales companies in general could be looked at as examples of viral loop applications, but I am looking for a way to somehow apply some of the elements that have worked so well on the social networks into the product packaging and total consumer experience.

    I probably misunderstand altogether, which is why I am hoping for some clarification and ideas. Maybe you could clarify a bit for me? Are there examples of viral loops in consumer products out there already? My main goal is to encourage the growth and consumer awareness of the brand.

    You indicate that “The fundamental psychology behind viral loops applies online and offline.” I see how that is true, but it seems that they are more easily engaged & encouraged online. How can viral loops be implemented and maintained offline?

    Thanks!

    Just one more thing….
    I know that social networks grow through members inviting others to “be a friend”. This actively encourages participation as new members do the same. New photo notification via e-mail prompts users to re-engage. This is an interesting element & would be helpful to apply offline in some way.

    Perhaps the term “viral loop” is new, and the widespread use (or attempt to use) is new, but the basic concepts and human psychology used by viral marketing techniques is not new.

    You have an product that is bought and consumed offline; will you have an online component? Will there be a way to use your online marketing to create a viral loop? If you're going to put pictures of people on the physical bags, can you use the web to solicit pictures and people stories? Will you let people promote themselves, spread to their friends, invite people to view and vote, allow the pictures to be viewed online, embedded, posted to social networks?

    Thinking of offline possibilities: the key is to understand the fundamental human behavior: why do people eat granola? How do the choose what they buy?

    But thinking simply, could you encourage people to actually look at your package? Could you make different packages unique? Could you get people to “tag” your packages? Could you make stickers for people to use to tag your packaging, or to tag your advertisements? Could you use QR codes to deliver more information through the packaging and get people to actually care about the unique packaging? Could you use RFID to tag specific packages with the pictures of people on it, to allow people to see the consumption of “their” packages throughout the states, or to be notified when “their” package has been tagged, or sold, or consumed?

    Just some random thoughts to start the thinking…

    I came across this interesting approach by Nike where every real shoe you bought grant you virtual items in a mobile social network.

    Imagine that the user put the virtual nikes on and friends can click to see the physical version you bought….

    That is a viral loop?

    It's viral, but it's only a loop if the invited people continue to pass it on. The key is to have viral actions available, easy to use and meaningful to each user in their own context at each stage.

    Some very interesting ideas here…
    I do see having a web property to complement the physical product and encourage discussion, buzz and interactive uses.
    I do intend to solicit photos on the bags and online and then let visitors vote .
    I do think that the ability to eventually infuse the product with an online viral component is absolutely necessary to creating something unique.
