We’re very pleased to welcome @AzuleneLabs to our portfolio as it announces we have led its $3.4 million pre-seed round.

Azulene Labs is creating the future of drug and materials development. While mechanical and civil engineers design new products with high-precision software, chemistry has traditionally been far less precise.

For example, even after 60 years of computer modeling, predictions of how tightly a drug sticks to its target protein are still routinely wrong by a factor of a hundred or more.

Azulene Labs is rebuilding the simulation stack to make chemistry and biochemistry modeling truly predictive for the first time. It is building high-accuracy physics-based foundation models that provide around 100 times the efficiency of competitors while being at least 200 times more cost-effective.

Co-founder @NicolasSawaya explains: “An airplane is specified down to manufacturing tolerances before anyone builds a prototype. A skyscraper is load-tested in simulation before a single beam goes up. These ‘macroscopic’ models are so accurate that you can put enormous trust in them. Chemistry has had nothing like this. Until now.”

“Chemistry should work the way aerospace engineering already works, where you design the thing in a computer, you believe the answer, and the physical object behaves as predicted the first time you build it.”

Azulene Labs uses quantum-mechanical training data that produces far more high-quality data and higher-accuracy AI models for the same amount of capital as other approaches.

While there have been significant advances in AI-based chemistry modeling in recent years, existing models routinely produce structures that are deeply inaccurate, or worse, physically impossible. Azulene Labs’ models are constrained to the laws of physics in ways that the current cutting-edge AI models are not.

The technology can make a significant impact on product development across pharma, agriculture, energy storage, plastics, and industrial chemicals.

“Imagine cancer medicines aimed at proteins the industry wrote off as undruggable decades ago; new antibiotics for infections that have stopped responding to everything we have; replacements for the solvents the chemical industry runs on by the megaton, many of which are toxic enough that regulators are phasing them out with no good substitute yet found, or plastics that perform like the ones we use today but break down completely afterward instead of persisting for centuries,” Sawaya says.

The new funds will be spent on expanding the team and further product development. The company is currently working with end-users in the biotech and industrial chemistry markets.

@noordende, our founder and General Partner, says:

“What we see in this company is exceptional founder-market fit at a time when the pharma market is hungry for exactly what this incredible team is building. Nicolas is the perfect person to lead Azulene Labs to become the Anthropic of chemistry.”

Our portfolio company @QuantWareHQ’s huge $178 million Series B round was the talk of the quantum world and beyond last week. But that’s not all the company had to share…

Alongside the announcement of the round, which we took part in having backed them from the beginning, QuantWare released a new whitepaper: Hyperscaling quantum processors with VIO™.

The whitepaper is an in-depth look at bringing quantum processors to the scale, economics, and industrial production needed to run the workloads that matter, at the costs that justify deployment. 

This is the route to unlocking a new realm of computing for finding new medicine, discovering new materials, and solving problems that touch the lives of everyone.

Quantum photonic chips sit at the heart of many of Europe’s most strategic emerging technologies, including quantum secure communications, quantum sensing and quantum computing. 

Our portfolio company Q*Bird is part of Photonics for Quantum (P4Q), a €50 million European project to industrialize the photonic chip technologies that will power the next generation of quantum systems.

Q*Bird is taking on a key role within P4Q as a lead user for the quantum communication use case. 

Together with its partners, Q*Bird will work on the designs and perform system-level testing for photonic integrated circuits tailored to quantum secure communication. This includes evaluation of entanglement quality and quantum teleportation capability. 

“The challenge is not building a single high-performance component,” said Dr. Joshuan Slater, CTO of Q*Bird. “It is ensuring that components perform consistently, under operational conditions and are producible at high-yield. That is what will define telecom-grade quantum infrastructure.�� 

“Europe must not only invent quantum technologies, it must also build the capability to manufacture and scale them,” said Dr. Ingrid Romijn, CEO and Co-Founder of Q*Bird. 

For Q*Bird, the project reinforces a clear mission to build secure, scalable and future-ready quantum communication systems for Europe and beyond. 

“With P4Q now underway, Q*Bird is helping lay the photonic foundations for the next era of quantum secure infrastructure, where industrial-grade performance, trusted security and scalable manufacturing go hand in hand,” adds Remon Berrevoets, CTIO and Co-Founder of Q*Bird.

We’re really proud of our portfolio company @QuantWareHQ today as it announces a $178 million (€152 million) Series B round.

We’ve backed them from the start, and we’re part of this round too: the largest ever private round by a dedicated quantum processor company.

QuantWare has come a long way in a short amount of time.

This round comes following the announcement of VIO-40K, a quantum processor architecture for 10,000 qubits, 100x larger than the state of the art today. The company is building KiloFab, the world’s largest dedicated quantum open architecture fab, in the Netherlands – strengthening Europe’s position in a value chain that is of key importance to its global strategic autonomy.

QuantWare is the only company that designs, fabricates, and integrates modular quantum processors on an open architecture at an industrial scale.

"The promise of quantum computing, capable of solving humanity's intractable challenges, can only happen once it can be manufactured and deployed at scale. That is exactly what we are building," said Matt Rijlaarsdam, CEO and co-founder of QuantWare.

"VIO-40K will deliver 10,000-qubit processors on an open architecture that the entire ecosystem can build on, and KiloFab gives us the industrial production capacity to meet rapidly growing global demand. This fundraise accelerates QuantWare, and in doing so, advances the entire ecosystem toward hyperscale quantum compute, and we're proud to do so from Europe."

Congratulations to Matt, Alessandro and the whole QuantWare team!
