Experimentation / CRO

Experimentation and Testing Programs acknowledge that the future is uncertain. These programs focus on getting better data to product and marketing teams to make better decisions.

UX / CX Research

Our research programs aim to characterize behaviors and perceptions of your core and adjacent customers.  Why? Because we want to change these behaviors and perceptions for the better.

Data and Analytics

90% of the analytics setups we’ve seen are critically flawed. Our data analytics audit services give you the confidence to make better decisions with data you can trust.

Data warehousing

There is now more customer data available than ever before, but for most businesses, this data remains siloed within different tools.

That’s where our data warehousing services come in. A data warehouse can resolve such issues and help you to draw better insights from your data.

What is a data warehouse?

A data warehouse is a database that is built to store and manage large sets of data.
Most well-known data warehouse vendors (for digital and marketing) include; 

• Google BigQuery
• Snowflake
• Amazon Redshift
• Microsoft Azure Synapse

While all of these do a good job in general, for companies that rely heavily on Google’s products (Google Analytics, Google Ads, GSuite, Google Data Studio, etc.), we recommend choosing BigQuery for the familiar interface and seamless integrations.

What’s the benefit of having a data warehouse?

Data warehousing will help you to:

• Improve the quality of your customer data
• Improve business intelligence
• Generate higher returns on investment by making smarter business decisions
• Create more accurate forecasts

What will my data warehousing project look like?


A well-planned data infrastructure should work for your business as you scale. In the planning phase, we’ll create a schema containing all of the relevant parts of your data infrastructure. This includes the list of sources, and destinations.

Building the infrastructure

Building the infrastructure means activating, configuring, and connecting the tools available within (usually) a cloud platform such as Google Cloud or AWS. Some parts will require writing custom code e.g  Python functions for piping and processing data.
When building data infrastructure, we focus on: 
• Reliability & accuracy
• Security
• Cost-effectiveness
• Flexibility 
• Future-proofing e.g scalability

Connecting the data sources

Wherever possible, we’re going to use ready-made connectors between data sources and your data warehouse. But if needed, we can build custom connectors too. This means we can pull data from any source that has an API or some sort of data export feature.

Business intelligence tooling

We connect BI tools and build the core reports and dashboards for you, so you can begin to explore your data and draw insights.

Monitoring, reporting & machine learning

There are countless ways the data we’ve collected can be used. This can range from user experience personalization to marketing campaigns or even machine learning for product recommendations etc.

Data Warehousing Case Studies

$1.5 million in additional revenue

For Procter & Gamble brand, Native, by experimenting and improving their customer experience.

0-100 experiments

We helped MongoDB embed an experimentation culture that took them from no testing to running 100 tests per year.

$2M additional revenue

A single research-backed recommendation for RevZilla delivered $2M in annualized revenue.

“I’d gone on your site and read everything. I thought these guys know what they are talking about. We had previously engaged with some of the biggest UX and CRO agencies in the country but it felt like they hadn’t even been on our website. Speaking to you guys, you’d already identified some issues on our very first call. We knew we were talking to the right people.”

Data warehousing FAQs

What are the benefits of using a data warehouse?

Most businesses have 5+ tools and platforms that are constantly producing and storing user data. This includes their analytics platforms, CRM, CMS, ad platforms, social media, marketing automation tools, A/B testing platforms, and more.
Having this data spread across multiple platforms will, sooner or later, cause problems like:

• Tools reporting different values for similar metrics (number of sessions, conversion rate, etc.)
• Troubles compiling data from multiple sources
• Tools aggregating data in a way that doesn’t make sense for your use case (i.e. session vs. user)

If your teams are reporting on similar metrics with different data, it’s a recipe for chaos. This can lead to people questioning your efforts. In many cases, the problem isn’t that the numbers are wrong, it’s that the numbers are calculated differently.

If any of those problems sound familiar, then you need a data warehouse; a central location where data from various tools and other sources is pulled together, in a raw format. This means that you can define how certain metrics are calculated, join data from different sources and find answers to important business questions.

What data should you store in a data warehouse?

The more the better.
Since the cost of storing data in the cloud has become relatively cheap, there is no reason why you shouldn’t store all the data you possibly can in your data warehouse.
Examples of the kind of data you might store in a data warehouse;

• Google Analytics (raw, hit-level, unsampled)
• Google Ads and other ad platforms (campaigns, cost, impressions, etc.)
• Back-end data (i.e. Shopify orders, leads, order data, customer data)
• Marketing platforms (Mailchimp, Klaviyo, Hubspot, etc)
• Stock/shipping/warehouse data

What's the difference between a data warehouse and data mining?

A data warehouse is a system used to store data. The data can then be queried using a query language like SQL.

Data mining, on the other hand, is a process. This can be part of the process of getting data into a data warehouse, but more commonly, it describes the process of accessing data already stored in a data warehouse to discover patterns, correlations, and find actionable insights.

What are the key elements required for a data warehouse?

To have a fully functional data warehouse you need to have at least the following elements;

• Data pipeline or an ETL process to get data into a data warehouse
• Data warehousing software (BigQuery, Snowflake, etc.)
• Schema of how the data is being transferred, modified, and stored
• A business intelligence tool for accessing data (Looker, Tableau, Power BI)

What is the purpose of a data warehouse?

Joining data from various sources
When sending data into a data warehouse, there should always be an ID/key that is also found in some other source/table. This can be a user ID, campaign ID, order ID, or something else. This then enables you to answer questions like;

• How many leads from [campaign X, experiment Y, source Z] converted into paying customers, and what is their LTV?
• What is the churn rate from a specific traffic source or user segment? How does it compare with other traffic sources or segments?
• What are all of the touchpoints for a specific user or a (high-value) user segment? (ad, email, website, support chat, phone call, etc.)

You can define your metrics 
In Google Analytics (and many other tools) you will start collecting data after you define a metric. If you change a metric, you will start collecting from that moment on with no view on the historical data.

If you have all the data available in your data warehouse, you can define your metrics, KPIs, goals, and funnels on the go. Modify them to your liking and immediately create a report based on your historical data. This helps you to answer questions like;

• What is the conversion rate of each step in an alternative funnel that I didn’t define before?
• What is the conversion rate for each traffic channel for specific user action, that I didn’t define as a goal?

Gain access to unsampled and unaggregated data
Google Analytics and many other tools aggregate data based on how they see fit. This includes how they define a conversion, conversion rate, session, bounce rate, etc. In many cases, this is not how the business itself would define them. I.e. the use of session vs. user for calculating metrics.

• Websites that receive lots of traffic are also affected by sampling.
• This means the reports you are looking at aren't based on 100% of the sessions (collected data), it may be an estimate based on say 5% of the data.
• With a data warehouse, there is no sampling. This helps you answer questions like;

Advanced dashboards and automated reports
With data warehousing, you can define metrics in your own way. This means that you can also use those metrics to build interactive dashboards, automated reports, and other types of visualizations/presentations based on your data. This allows you to build reports/dashboards for;

• Monitoring your A/B testing program, including data from Google Analytics, testing tools, and the back-end data.
• General business performance, including data from various sources, funnels with touchpoints in different platforms, etc.
• Specialized reports such as LTV, churn, user journey, etc.

Monitoring, machine learning, and other clever use cases
With a data warehouse, you have access to raw hit-level data, often in (near) real-time. This is the kind of data you can use for monitoring systems or building machine learning for things like marketing automation and product recommendations.

Some ideas; 

• Use machine learning to detect the traits of high LTV customers. Show ads and send customized marketing messages to this audience.
• Configure a real-time monitoring system to detect changes in any critical metric. (i.e. alert you if the conversion rate for a specific device goes down)
• Use data from GA and other sources to show/send more accurate product recommendations.
