The Metric Watched By Top Startup Growth Teams

It is easier to create technology products today than it has been in the past (and only getting easier). With more entrepreneurs building new products, the competition for people’s attention is accelerating. I used to think that building a great product would result in press and demand for your project; but I now know that is naive. Even if you build a wonderful product, it doesn’t mean that people will flock to use it. You need to be maniacal about understanding how many people are using your features, and improving your metrics over time.

Dave McClure’s pirate metrics are an invaluable model for analyzing SasS metrics, but little has been written about them. Each of the metrics are not all immediately valuable and actionable as you first start building a product, but one of the ones I think that is valuable (and critical to start measuring) from the very beginning is an activation event.

What is an activation event?

I like the KissMetrics definition of activation:

Activation is: The first point where you deliver the value that you promised.

Source: https://blog.kissmetrics.com/saas-activation/

Activation Examples

Some examples of activation (I don’t know if these are their real activation events):

  • DropBox: Your first file is backed up from your computer into the cloud
  • Facebook: You connect with 7 friends within your first 10 days
  • Stack Overflow: Your question is answered
  • Instacart: When your groceries are delivered for the first time
  • Instagram: Someone likes one of your photos

Key Elements of An Activation Event

There are key elements of an activation event that make it so valuable:

  • It happens once.  Once someone has activated, they cannot activate again.
    • This defines cohorts (daily, weekly, monthly) analyzed over time.
  • It represents real value for users. It’s shouldn’t be a “bullshit metric”.
  • It gives you a sense of how efficient your acquisition funnel is / how well you do at getting people to see value in your product. This is the activation rate.

Not everyone who signs up for your service is going to be able to use it / get value from it. Over time, you should be optimizing for the percentage of people who can use your product, and then how many of these people come back and use your product in the long term. I have been using MixPanel to do this in my time on the Sidekick team, but any good analytics tool will be able to give you this type of insight.

Measuring impact based on activation

Some of the things that we track based off our activation rate:

  • What is our overall activation rate?
  • What is our overall activation rate by channel?
    • For example: Paid Acquisition (platform, campaign, audiences), Content Marketing, Social Channels, SEO, Virality. You might choose to stop pursuing channels because the activation rate is too low or adjust your strategy to improve activation rate for a single channel.
  • What is the time it takes someone to activate? Can we decrease this time?
  • What is our retention of activated users over time?
    • If a user doesn’t activate, I highly doubt they’ll keep using your product over time. By focusing on cohorts of activated users, you can optimize towards a ceiling that reflects an attainable goal
  • How does our activation rate improve over time?

When to start tracking activation

When you’re first building your product, you should be speaking with all of the people that are using it. Once you get past those first 100 users, it’s hard to speak with everyone. That’s when having an activation event will give you an indication of whether people saw value in your app, and whether they’re likely to want to continue using your product. Even in your earliest days, it’s important to have an idea of what you expect people to do in your app and how many of them accomplish that task. Since it is a percentage, it is valuable when you’re the size of Facebook or for your first 1,000 users. As you grow, you will learn more about your users, your business, and how to optimize for success and activation over time. As you learn more, you can refine your activation event as you learn and collect more data.

The Hard Secret About Optimizing Week 1 Retention

Having data about how people are using features has revolutionized how I go about building and growing products. One of the key metrics that I’ve spent a lot of time optimizing is week 1 retention. It answers the question: of the people that start using your app, how many of them are still using it one week later?

Retention reports solve exactly this problem, but they can be confusing to interpret. MixPanel produces analytics software that produces retention reports, and they do a decent job of describing all of the information in their retention help article. While they are fairly intuitive, there is a subtlety that is hard to wrap your head around:

the beginning and ending of each bucket will be different for each customer in the cohort

That means that each person has their own “1 week” cohort, and that it takes 3 weeks for a single week to “mature” if you’re looking at week 1 retention. Here’s a good example:

retention cohort

In this example, we’re looking at users who activate the week of August 4th. That means that someone counts within this cohort when they sign up between 12:00 AM on Monday the 4th through 11:59pm on Sunday night the 10th. While people who sign up at different times both part of the 8/4 cohort, they each have different periods that represent week 0 and week 1. An example of two people in the 8/4 cohort:

  • Signup on 8/6 at 12pm:
    • Week 0: 8/6 12pm – 8/13 11:59am
    • Week 1: 8/13 12pm – 8/20 11:59am
  • Signup on 8/10 at 11:59pm:
    • Week 0: 8/10 11:59pm – 8/17 11:58pm
    • Week 1: 8/17 11:59pm – 8/24 11:58pm

This means that it takes 3 weeks for a cohort to fully mature so you know what the final week 1 retention percentage is. You won’t know the week 1 retention percentage for the 8/4 cohort until 8/25, when all of the users have been given a chance to be active in “their” week 1.

This makes analyzing and optimizing for week 1 retention very difficult, since it takes a long time to fully understand the implications of changes you’re testing. If at all possible, our team looks for early indicators of retention and leverage those as much as possible until we have our mature cohort percentages.

An Insider’s Look At HubSpot Sidekick’s Growth Approach

This post was originally published here on onstartups.com. It describes the process that I use in my day to day activities working on the sidekick team.

The Sidekick growth team is a small, data driven and aggressive group within HubSpot that works on new, emerging products with massive audiences and a freemium business model (similar to Dropbox and Evernote).  We are constantly pushing ourselves to learn new growth strategies, tactics, and techniques. I have personally become more data driven and model driven after joining the team, and wanted to walk through an example of one decision that became much easier with the use of our generic problem solving framework.

I am a big believer in the idea that complicated problems look simple when you are able to break them down.  Don’t take my word for it – this is what was attributed to Einstein:

If he had one hour to save the world he would spend fifty-five minutes defining the problem and only five minutes finding the solution

The Sidekick growth team follows a very straightforward process that strives to take complicated choices, and analyze them to produce areas of opportunity:

Step 1: Choose a goal

Step 2: Build a model

Step 3: Analyze the inputs

Step 4: Identify opportunities

These steps are generic enough that they can be applied to many kinds of problems.  Whether you’re on a sales, marketing, product, support, services, or any other type of team this framework is incredibly valuable.

Step 1: Choose a goal

Choosing the right metric / goal is very challenging and critical to our success.  If our team optimizes for the wrong metric, it doesn’t matter how well we execute because our efforts won’t translate into success.

Our identified goal:

We ultimately chose to define our goal as increasing the number of people active on a weekly basis.  Rather than pick any metric, a person has to take one of six key actions to demonstrate that they are getting value from our product.  Brian Balfour talks about the cycle of meaningless growth here, but the key takeaways for our product are that more people using Sidekick helps us to grow faster.

Some of the attributes we used when picking our goal:

  • It is a holistic representation of our product. We thought about all of the ways that someone uses Sidekick, and thought about the best way to represent them.
  • It’s authentic (hard to fake).  If you optimize for a hollow metric that is easy to attain, but doesn’t translate into success later on, you might fool yourself into thinking you’re making progress. If we were to pick signups, we might crush that goal and get a lot of users to sign up, but they might not stick around.
  • It represents real value.  If you solve for your own needs instead of the customer’s needs, you may be successful in achieving your goal but it won’t translate into true success down the road.  We tried to pick a goal that represented users getting value out of the product, which results in people upgrading to the paid version of Sidekick.

Step 2: Build a model

With the goal established, we then set out to build a model to understand what will have the biggest impact on weekly active users (WAUs).  If we simply tried to increase our top level goal on its own, we wouldn’t have an understanding of where to start.  In order to understand where to focus our efforts, the model breaks down the goal into manageable pieces.  The whole point of building the model is to understand what the inputs are, and what the biggest contributor to our goal is.

Our Excel model breaks down our goal (WAUs) into the individual components that drive it on a weekly basis.  It’s a simple equation:

WAU = (New people) + (People from previous weeks who continue to use Sidekick)

We broke down each of these two buckets into their individual components.

WAU =

  • New People:
    • Channels:
      • People we acquire through paid acquisition
      • People we acquire through content marketing
      • People we acquire through SEO
      • People we acquire virallly from existing Sidekick users (invites, etc)
      • Activation Rate
        • Not everyone who signs up ends up using the product.  Therefore, we measure the people who install our software and get it up and running correctly through an activation rate. Rather than look at the activation rate across all channels, it’s important to understand how each one is different, and if there are isolated pockets ripe for improvement. For example: users who read our content are more likely to set it up than someone who clicked through on an advertisement before signing up.
  • People from previous weeks who continue to use Sidekick
    • We look at the number of people who sign up each week, and then look to see how many of them are active each week since they signed up.
    • We look at retention, which is critical in freemium businesses.  In order to accomplish our goal of having millions of users, we have to retain the users we acquire.

This is a screenshot of our model:

The numbers in this screenshot have been changed so they are not reflective of our true numbers.

Step 3: Analyze the inputs

The model above is extremely valuable because it allows us to use our week-over-week growth to forecast the long term impact of any change. It’s incredibly hard to understand how multiple factors could interact over a long period of time. It might be possible for someone to reasonably predict the implications of any change, but without the model it is easy to be short sighted.

With our model built, it was easy for us to test the sensitivity of the inputs.  For example, if we were to increase the number of users we acquire from our paid acquisition budget, how would that impact our WAUs in a year? Instead, if we focused on retention and user acquisition rates stayed the same, would we have more users a year later?  What about if we improved the conversion rate for a different area of the funnel?

Rather than sporadically tackling new campaigns or projects, the goal is to understand what is the most impactful focus area for the business.

In looking at the Sidekick funnel, we found that two of our biggest drivers were retention and viral growth.  We modeled how changes to each of them would impact our goal, and decided to focus on retention first before looking at increasing the number of new people through viral channels.  At the end of the day, some of the factors that we always consider:

  • What is the current state of the metric?
  • How much do we think we can improve this metric?  What’s the ceiling on any improvement?
  • What are the resources required to have a meaningful impact?  How long would it take?

Factoring in answers to those questions, and including the estimates in our model, we decided to focus on improving our retention in Q4 2014.  There was a lot of analysis that went into picking retention; it was the result of repeating Steps 1 through 3 multiple times.  By going through the process of evaluating different levers in the model, it becomes much easier to weigh different options against one another and impartially judge alternatives.

For the Sidekick team, it wasn’t as simple as saying that we wanted to improve retention.  Just like WAU’s, retention in itself has many inputs that we had to evaluate.

  • Of the people that stop using Sidekick, we lose the majority of them in their first couple of weeks
  • In the hypothetical example below, we have sample numbers of how we retain users over time:
    • 45% of a cohort stops using Sidekick one week after signing up
    • 5% of a cohort stops using Sidekick two weeks after signing up
Cohort Size Signup Week Active 1 Week Later Active 2 Weeks later Active 3 Weeks Later
100 11/3 55 50 45
110 11/10 61 55 50
120 11/17 66 60 54

The numbers in this table have been changed from their real values for this post

  • Given the size of our user base, we determined that week 1 retention was our biggest issue and opportunity.  If our existing user base was larger, our long term retention might have been a more important issue.  The lesson is that your biggest areas of opportunity depend on your current context.

Once we isolated the fact that people stopped using it after their first week, we set out to understand why someone who installed Sidekick would stop using it after they signed up.

Step 4: Identify Opportunities

At this point of the process, we know what’s most important to our goal and the implications of an improvement.  The next step is to start identifying how we can make an improvement.   Depending on the lever, there’s a mix of elements that are helpful in breaking down the opportunity.  We used quantitative analysis to identify a problem segment, qualitative analysis to flush out its symptoms, and used our understanding of our product to come up with ideas to address the issue.

To identify a problem area, we did a quantitative analysis of the people that only used Sidekick for a single week.  We looked to segment these users to look for patterns, such as:

  • Where were these users coming from?  Was there an issue for a single channel of users?
  • What technology were these users using?  Was it an issue with Gmail, Microsoft Outlook, or Apple Mail?
  • What part of the application were they using the most?
  • How much do they use Sidekick?  How many days did they use it?  How much did they use it their first day?

In asking these questions, we found that Gmail users were more likely to stop using the product when compared with other email clients. This was a complete shock to us.  We had figured that Gmail would retain fairly well, and that an issue would be likely to exist in one of our other email clients.  We found that a large number of these people were only active the day that they signed up.  To understand their usage on their first day, we created a histogram that showed how many tracked emails this population of users sent their first day.

For the Sidekick team, it wasn’t surprising that people who only tracked a single email their first day didn’t come back.  The surprising element was that such a large % of these people were only tracking one email.  We wondered why someone would go through the Sidekick onboarding process only to never use it again.  Wouldn’t you at least test it out with a couple of friends or coworkers?

To understand why these people stopped using Sidekick, we sent out a simple email to a thousand users.  I emailed them individually by BCCing them from my HubSpot account, asking for feedback on a specific question designed to bring insight to the pattern we discovered.   We bucketed the replies to our email, and found that there were big opportunities to improve our week 1 retention.

reasons why people churned

The numbers in this chart have been modified from their real values for this post.

I was personally ecstatic when I saw these distributions.  It wasn’t that a competitor was better, or that there was a mismatch between the features people were looking for and what our product offered.  The issue was a psychological one:

We weren’t doing a very good job explaining what our product did, and how people could get value from using it.

Rather than having to build a lof of new features, we needed to experiment with explaining the value of the product.  It’s much easier to test out different ways of describing the product than addressing weird edge cases or building entirely new features.

With our quantitative analysis done and having received qualitative feedback from the segment of users we were most interested in, we spent time brainstorming ideas to address the opportunity.  We looked at how competitors accomplish the same task, how companies in other industries educate their new users, and researched why our most passionate users like Sidekick.  I’ve included a list of sample experiments we’ve tested:

  • Only show the Sidekick web application once we have value to demonstrate
  • Show a video of someone using Sidekick and how they get value out of it
  • Ask users whether they intended to use Sidekick for personal or business use cases, understand whether we should try to change their mind or give them examples that align with their mind set
  • Show a narrative of how someone uses Sidekick over a period of time
  • Incorporate our onboarding into the Gmail interface rather than in our web app

Conclusion

Looking at the opportunity we have focused on for Q4 2014, it seems kind of simple and obvious.  By setting an appropriate goal, understanding the inputs to that goal and finding the biggest contributor, it led us down a path to clearly define our next steps.  While finding a solution isn’t guaranteed, the team is confident that if successful it’ll have a big impact on our trajectory for 2015.

This framework isn’t perfect and isn’t for everyone, for instance, if you are creating a new product or process and have a small sample size.  However, for the Sidekick team, this process has been an enormous help in prioritizing where to focus energy and resources and get the team aligned behind a common goal.

This framework is incredibly valuable to the Sidekick team for multiple reasons:

  • It breaks down large, complicated problems into actionable and manageable tasks.
  • We have confidence that the opportunities we are working on will have a big impact.
  • We understand the relative importance of different initiatives and are able to make conscious decisions about areas to pursue and the resulting trade offs.  It’s also easier to decide what we shouldn’t be working on, even if it may feel important.
  • Our team can see the direct impact on individual metrics, and understand how any improvements translate into the success of our team.  Teams like being able to track their progress and see how their efforts translate into success.
  • It’s a repeatable and scalable process.
  • The insights aren’t isolated to technology solutions – they can be as simple as messaging and the steps instructions are displayed.

Great!  How do I apply this?

Your time is extremely valuable. Whenever you can, make data informed choices.  You don’t have to be a slave to your model, but you should be making conscious decisions about what you’re focusing on and why it’s most important. Hold your colleagues accountable – ask them why an initiative is important, and what the impact will be.

The mantra of our team is that we want to be the best at getting better.  If you’re interested in learning about growth and seeing your contributions all the way to a business’ bottom line, our team is hiring.  You can see a list of the open positions here.

Thanks to these wonderful readers for their feedback: Brian Balfour, Anum Hussain, Maggie Georgieva, Jeremy Crane, and Andy Cook.
