Our US deal announcements keep coming. 

Meet EuQlid, a quantum tech company working to deliver a breakthrough 3D imaging solution for semiconductor and battery product development and manufacturing.

Today they’ve come out of stealth with a $3 million raise and over $1.5 million in revenue. We led the round, with participation from Quantonation.

EuQlid’s proprietary quantum imaging platform enables non-destructive mapping of buried current flow with unprecedented precision inside complex materials and devices. 

Global demand for advanced metrology and inspection tools exceeds $10 billion annually and is growing rapidly with the adoption of 3D architectures.

The company’s quantum-based technology addresses a critical gap in the semiconductor and energy storage industries, visualizing sub-surface currents with precision and speed, where today’s inspection and test tools cannot reach, for new product development and high-volume manufacturing yields. 

EuQlid’s first-generation Quantum Diamond Microscope (QDM) product for geosciences and bioimaging applications has been delivered worldwide and is in use at Harvard University and New York University in the USA, Oxford University in the UK, and Curtin University in Australia among others.

Sanjive Agarwala, co-founder and CEO of EuQlid, explains: 

“Our mission is simple. We want to make quantum precision available now, addressing fundamental 3D metrology and inspection whitespace, to enable the next era of semiconductor and battery revolution.”

Our investment director Kris Kaczmarek says:

“We are thrilled to lead the investment round in EuQlid, a company founded by true pioneers of diamond-based quantum sensing and guided by a seasoned semiconductor executive, addressing a critical bottleneck in advancing the next generation of semiconductors and batteries.”

The pace is really picking up at QDNL Participations, and I’ll have a lot more to share with you soon.
