Causality´s Partners

Centrality Logo

Auckland-based Centrality is one of the leading, blockchain venture studios in the world, with a growing team of 75 people across Auckland, London, Melbourne and Singapore. They’re backed by a global investor network who understand their vision – to help the world transition to a blockchain-enabled future.

As a decentralised eco-system, Centrality connects different applications together using Blockchain powered technology. This technology allows businesses to work together to gain scale through shared acquisition of customers, data, merchants and content. Blockchain enables smarter transactions because it’s managed by a network, not any one central authority. We call this ‘decentralisation’, which basically means the network operates on a peer-to-peer basis – no middle man.

Centrality has built a scalable platform, software and a library of components that businesses can use as building blocks to create a decentralised business.

Smart Associates Logo

Formed in 2003, Smart Associates has gained a reputation and an extensive background in the provision of data warehouses and data lakes. Implementation sizes range from 50Tb to 5Pb giving business insights and capabilities previously un-catered for. The company has people with work experience across data architecture, data science, software development, product support, management consultancy, legal and finance. They have managed large data migration and integration projects for clients in retail, insurance, banking, financial services, telecoms, healthcare and other industries in both Europe and Asia Pacific. They are experts in combining and enriching data from multiple internal and external sources.

Smart Associates has a global presence with hubs in both Europe and Asia Pacific and a global client base supported by data engineering and data science skills around the clock. This is achieved, in part, through partnerships with key providers such as IBM, Oracle, Hortonworks, Thoughtspot and DataRobot and now Centrality,  through the use of their own repeatable and scalable processes and products.
