We are live! 🚀

Yesterday morning we officially launched our latest crowdfunding round on Crowdcube, and the response has been overwhelming.

In just over 24 hours, we have already surpassed £131,000 with 154 investors joining the vault. Today alone, we have seen over £40,000 in new investment.

This funding is the fuel to move us from proving our technology to growing the business. Over the next 12 months, we are delivering:
✅ Executing more projects to meet our pipeline demand.
✅ Launching Cold Vault for industrial cooling in AI Data Centres.
✅ Expanding our reach across the Nordics and beyond.

To the 154 people already on board: thank you. To those of you who have been following our journey from the drill rig to the data centre: we’d love to have you join us for this next chapter.

Don’t invest unless you’re prepared to lose all the money you invest. This is a high-risk investment and you are unlikely to be protected if something goes wrong. Take 2 mins to learn more: https://www.crowdcube.com/explore/risk-warning

FROM PLANNING TO PHYSICAL EX*****ON 🇸🇪

A quick update from the field. We are currently on-site in Halmstad, Sweden, where our drilling rig is on the ground for our first flagship commercial project.

This 10 GWh facility is being delivered in partnership with the Swedish Energy Agency and HEM. Seeing the rig in action marks our official transition from technology development to commercial delivery.

We are moving fast. If you'd like to follow our progress or join us on this journey as we scale, you can find the link to our early access investor page in the first comment below. 👇
