We utilise data to grow your business

The Quarry is a data science consultancy working with high growth businesses and scale-ups.
We help you delve in to your data to expose insights that can grow or optimise your business.

When you should work with us

The problem

1. Data scattered over a wide number of platforms, from many sources

Data originating from different sources is usually of different types. This data diversity requires additional transformations before analytics can be applied, making the process inefficient and costly.

2. Lack and expense of talent

(A game changing) Methodology needs top talent and is hard to define and validate. A single data scientist can’t do everything on their own, you need a diverse team and expert leadership. And most of the time this talent is prohibitively expensive.

3. Companies want to keep data science in-house

However, the large part of data science is better done by specialists who can create and do a straightforward handover to a mid tier python developer to handle.

4. Reporting to stakeholders is difficult

You don’t want to be focusing on how to create reports for your stakeholders and VC’s when you have a product to build and customers to attract.

5. Assumptions that aren’t always validated by data

This can lead to guesswork often resulting in expensive and/or irreversible mistakes.

How we work



Data Science

Business intelligence

The focus of data engineering is to extract, aggregate, and structurize often unstructured data from various disparate sources that your employees commonly use on a daily basis.

Data warehousing/ETL
The groundwork for all data science projects.
We extract (scrape), transform (preprocess and filter), and load the data into the data warehouse which is most appropriate for your case.

Why you need this: Your data is not in the right shape or format to be processed.
Data modeling
We clean the data, create relationships, aggregate and choose the most suitable layout for data points. In this process we shape the data into the appropriate structure that is best for analysis and optimal processing or querying.

Why you need this: Fitting your data to data models, we are able to apply processing methodologies to it.

Data analytics offers diagnostic insights into business performance. This gives in depth understanding of the key root causes behind behaviour combined with business intelligence.

KPI measurement
KPI measurements allow business decision makers to shed light onto their business’s performance. Here we identify, while directly communicating with your decision makers, the KPI’s most relevant to your business.
Once KPIs are defined, our team designs methodologies to process the data and extract the KPIs. Most startups have similar challenges and similar KPIs that need to be extracted, relating to customer acquisition and retention, profit margins, conversion rates, activation and net burn rates, gross merchandise value, lifetime customer value, churn, or whatever is most relevant to you.

Why you need this: You need an accessible, high level overview of your business.
Event tracking
In marketing analytics, event tracking is a flexible activity that tracks individual customers interactions with your platform. We setup selected event tracking tools to bring another level of insights in to customer behaviour and psychology to the decision makers.

Why you need this: To observe users’ behaviour and be able to setup meaningful user testing.

Data science uses predictive modelling to assess your future trends and can identify key factors to reach a desired state in the future.

Predictive Business Analytics
We can use both large and small data sets to define data models and use them to predict the future. Over time, we feed these models with more data in order to improve estimates. This allows us to find trends and identify patterns, even within large sets of foggy data. This type of data science is particularly relevant for businesses that need to define newly emerging markets and their trends.

Why you need this: To be able to forecast and act on customer trends and use that to acquire / retain them.
Predictive customer analytics and churn
Here we can predict what the customer wants, who they are, and why they like a particular product.
Customer churn is among the most important indicators for SaaS startups, especially when trying to identify individuals on the brink of churning (cancelling). To prevent churning, we identify the indicators relevant to churn. Then we develop methodologies for the detection of changes in these indicators. Finally, we define and train a model to predict how your customers will behave in the future.

Why you need this: Because gaining customers isn’t always the most difficult part, but keeping them is.

Business intelligence is assessing the results from data analysis providing understanding to why something is happening and transforming the knowledge into actions directly applicable to your decision making process.

Business insights analysis
Data analytics and data science will generate appropriate KPIs and insights into the data providing what is happening in your business, which will then serve the business intelligence team to provide answers to why something is happening. Understanding reasons behind the growing or declining trends observed in the KPIs, or predictive models indicating surpassing warning thresholds in the near future is crucial for decision making to guide the business towards stability and success.

Why you need this: Understanding accurately the root causes for any trends will enable you to recreate growth where it is happening and find ways to mitigate any decline.
Data visualisation
As we work with you on the previous processes, a data visualisation expert will work with us to make sure that your data tells a story by presenting it in the most readable and approachable way. By visualising data, we can help you spot patterns, trends and correlations, allowing you to see the bigger picture.

Why you need this: Large datasets are impossible to comprehend for humans and can require supercomputers to find patterns. But with the right Business intelligence we can find out the best data to work with, and the best way to visualise and comprehend.


2 Week Sprints – Cancel anytime!


Why 2 week sprints?

Because it is just enough to get you deliverables while minimising risk.

What do I get out of a typical sprint?

You get an actionable insight, how big it is depends on your requirements and the complexity. But we never start a sprint before clearly defining all deliverables.

How many sprints will I need?

We can tell you an estimate based on our first call. A typical small project would require 3-4 sprints, and in some cases it can be less.

Do I need data science?

Yes. But that is the wrong question to ask.

Ok rephrase. How do I know how much I should invest in data science?

It depends how crucial it is to your business. But generally, a reasonable average spend for a company in the last few years is 2-5% of their annual budget.

How many people do I need in the company to operate and maintain the data products?

Typically a mid-tier developer should be able to handle any maintenance work and update without it taking all their time.

Who is the main user of the data products?

C level team members use data outputs to drive high level strategic level decisions, but it is best exploited when used by everyone in the team from business development managers to marketers.

What tools, stacks, and languages do you use?

Where are you located?

We are based in London next to Old Street Roundabout, but we have worked remotely with companies all over Europe.

I’m sold. When can we start?

As soon as we can get things sorted. Depending on the project, can be a couple of weeks, but sometimes we are booked for months.
