A Smart Data Economy is the roll-out of Open Banking-like data sharing across sectors, including: energy, finance, home buying, retail, telecommunications and transport.
The UK Gov Digital Strategy has stated that building a Smart Data economy could unlock £149 billion of organisational efficiency and £66 billion of new business and innovation opportunities in the UK economy.
Meaning the Smart Data economy is potentially worth a total of £215 billion over five years… if implemented properly and completely.
