Quantum computing is poised to reshape industries—and Israeli startup Classiq is leading the charge with its breakthrough software platform. The company has just closed a record-setting $110 million Series C round, the largest ever for a quantum software firm, as it positions itself at the core of the emerging quantum ecosystem.
The round was led by Entrée Capital and joined by a long list of new and returning investors, including Norwest, NightDragon, Hamilton Lane, Clal, Neva SGR, Phoenix, Team8, IN Venture, Wing, HSBC, Samsung Next, and QBeat. This brings Classiq’s total funding to $173 million, giving the company the firepower to scale globally and deepen its work with national quantum initiatives and enterprise partners.
“We are building the Microsoft of quantum computing,” said Nir Minerbi, Classiq’s CEO and co-founder. “In this new era of computing, Classiq is delivering the essential software stack to empower real-world quantum applications.”
How Classiq’s Software Powers Quantum Programs with Millions of Gates
Founded in 2020 by Minerbi, Amir Naveh, and Dr. Yehuda Naveh, Classiq is known for its pioneering quantum development platform—a fully integrated environment that makes it possible to design and compile complex quantum programs without deep quantum expertise.
At the heart of the Classiq quantum software platform is an automated compiler and development environment that allows users to describe what they want the program to do, and then generates the required quantum circuits—automatically and at scale. These circuits can contain millions of gates, a task that would otherwise be impossible to build manually.
The result? Quantum algorithms that are not only hardware-agnostic but also dramatically optimized. The platform can reduce quantum circuit size by up to 97%, cutting error rates and enabling faster deployment. Real-world use cases already include collaborations with global enterprises like Mitsubishi Chemical and Deloitte, where Classiq’s tools accelerated application development in chemistry, materials science, and optimization.
Beyond its core tech, the company has also filed over 60 patents on its quantum modeling and compilation technologies—all of which have been accepted. Its engineering team includes top minds in quantum physics, compiler design, and software systems, drawing from years of research and commercial expertise.
The company has more than tripled its revenue and customer base annually and now works with quantum research teams at BMW, Citi, Rolls-Royce, Toshiba, Mizuho, and dozens of academic institutions. It partners with cloud leaders like Microsoft, AWS, and NVIDIA, and supports deployment across IBM, IonQ, Rigetti, and other quantum hardware providers via major cloud platforms.
With quantum computing still in its early days, Classiq stands out by offering a high-level abstraction layer that translates business and research needs into quantum programs—faster and at greater scale than traditional approaches.
According to Avi Eyal, Managing Partner at Entrée Capital, Classiq is “building the operating system and compiler for all quantum computers.” In a market still defining its standards, that’s no small ambition—but with this funding and momentum, Classiq is well on its way to making that vision real.
