Who We Are

PlatinumDEX (UK) Limited is a UK and EU registered limited fintech company. We are built on four distinct yet synergistic pillars. They are cyber security, the cloud, renewable energy technology and finance.

Our aim is to change the paradigm by providing both data and energy security for both business and nation states. We are building and securing new forms of critical infrastructure. We are working with some of the most renowned contractors, architects and quantity surveyors in the world. We will satisfy the global demand for highly secure cloud computing, while taking a leading role in harnessing and developing renewable energy.

Our business proposition is unique as there is no network of carbon-zero, security biased cloud, powered by renewables. Customers will enable their own energy security by decreasing dependency on fossil fuels; and as beneficiaries of our security cloud, be protected from outside interference against their critical infrastructure.

Sustainability is core to our belief. We recycle where we can, including our offices and data centres. We will host in repurposed facilities, including bunkers, vaults and other reinforced complexes. Each site will be powered by its own waste to energy (WtE) power supply. Energy surplus to our needs will be fed into local power grids.

We are building a ‘world first’ network of entirely zero-carbon, highly secure infrastructure in our dark site ‘digital fortresses’.

The ‘glue’ to this business model is finance and our ability to bring funding to nation states for the design, build and deployment of new energy facilities, including wave and waste to energy technologies.

Our team compromises veterans in security & cyber security; banking & governance, engineering & renewables, digital ledger technology, artificial intelligence & machine learning. Details of the senior management are available on this website.

Collectively and historically, we have arranged over $50 billion in debt through a combination of project, structured, corporate, commodity, Islamic, financial institutions and Sovereign debt across all regions. We have extensive experience in working with all export credit agencies around the world as well as Multilaterals and Development Finance Institutions.

We are expert in arranging financings at competitive costs and are currently negotiating with nation states on critical national infrastructure projects including public health, data and energy, over 9 figures in value.


Meet Our Brilliant Minds : The A-Team

To achieve its goals, PlatinumDEX has put together a team of exceptional quality. It is our experience of artificial intelligence, security architecture, audit, banking, blockchain, cyber security, digital ledger technology and other skillsets when combined that is unique in our ecosystem. It gives us competitive advantage.
