UK startup Greenpixie raises £4.7M to reduce AI and cloud energy waste

UK-based startup Greenpixie has raised £4.7 million in a pre-Series A funding round. The company helps large enterprises reduce wasted energy, carbon emissions, and unnecessary costs from cloud computing and AI systems. Large companies such as Mastercard already use Greenpixie’s technology to improve efficiency. By cleaning up unused resources and optimizing cloud usage, businesses can reduce emissions, water use, and operational costs at the same time.

The round was led by VERBUND X Ventures, the venture arm of one of Europe’s largest renewable energy producers. Other investors include Octopus Ventures, Armajaro Holdings, and Green Angel Ventures.

The funding comes at a time when energy use from digital infrastructure is rising fast. According to industry estimates, data centres account for up to 6% of electricity use in the UK and the US. This number is expected to grow further as artificial intelligence becomes more widely used in business.

At the same time, research suggests that around 29% of enterprise cloud usage is wasted. This happens because companies often lack clear visibility into what is running in their cloud systems. As a result, unused or unnecessary computing resources continue to consume energy and money.

Greenpixie aims to solve this problem through software that gives companies better insight into their cloud and AI usage. The platform connects with major cloud providers and helps IT teams identify inefficient systems, including so-called “zombie resources” — services or processes that are still running but no longer needed.

One of the company’s key goals is to help firms make smarter decisions about where and how they run computing workloads. This includes choosing lower-carbon regions and optimizing AI workloads to reduce environmental impact.

With global cloud spending expected to exceed $1 trillion in the coming years, demand for “FinOps” and “GreenOps” tools like Greenpixie’s is increasing quickly. The company positions itself as part of a broader shift toward making digital infrastructure more sustainable.
