Big Data Partnership is EMEA’s leading Big Data specialist solution provider. We help organisations unlock the value in complex data by offering proven expertise in Consulting, Data Science, Engineering, Training and Support. Our vision is to become the best and most trusted Big Data service provider in the world.

Companies are generating data at a faster rate than ever before and are continuing to outpace the growth of storage capacity. A significant proportion of the driving force behind this explosive growth is in form of unstructured data which has been created from relatively new sources including social networks, mobile content, and machine data, all of which create massive complex data sets. In an information society where data is now the new currency, Think Big firmly believe that making sense of this data in an economically viable way will drive new revenue streams and give customers competitive advantage that were never before possible using traditional data warehouse and business intelligence solutions.

Think Big helps organisations to identify use cases to address their Big Data challenges and more importantly realise value from it. This encompasses end-to-end consultancy from data strategy, technology enablement and application of data science techniques. Our Consultants are certified industry experts who have worked extensively with Big Data technologies and toolsets including the Apache Hadoop ecosystem, Apache Cassandra and other NoSQL databases, Apache Spark and search technologies including Elasticsearch to provide scalable and reliable data solutions.
