Our take
Lloyds Bank, part of Lloyds Banking Group, began operations back in 1765 and is nowadays one of the UK’s leading retail and commercial banks. As with many leading banks, the company has dealt with its share of controversy, but it has nonetheless stood the test of time and worked to build back its public reputation in the wake of these setbacks.
As part of its ongoing digital transformation, the company is seeking to put the cloud at the front of its services and systems, and has cited intentions to invest heavily in overhauling its technology infrastructure. All this seeks to serve the modern banking customer, and to compete with the fast-increasing number of alternative banking options appearing on the market.
On top of this, Lloyds Bank has shown great interest in facilitating innovation in the industry, joining as a partner on "FinTech Action Labs" to bring its industry expertise to early-stage FinTechs. The company continues to enhance its online and mobile services (it is the UK's biggest mobile bank), as well as expanding its partnerships with digital banking companies.
