Oratomic, a quantum computing startup, raised $475 million three months after its Series A, the latest sign of growing investor enthusiasm in the emerging technology.
The Series B round was co-led by ARCH Venture Partners, Spark Capital, Khosla Ventures, Index Ventures, General Catalyst and Bezos Expeditions, bringing the company’s total funding to date to $775 million and lifting its valuation to $5.4 billion from $1.5 billion.
Oratomic, founded in 2025, joins a growing class of multibillion-dollar quantum startups building the technology that promises to solve problems far beyond the capabilities of today’s best supercomputers, with applications across pharmaceuticals, materials science, and other industries.
Oratomic CEO and co-founder Dolev Bluvstein said the company’s approach better positions it to focus on the right problems. “You can design a rocket that goes up 50,000 feet and falls, but it’s not even clear that you are going to be solving the same challenges as the one that goes to orbit,” he remarked.
Oratomic has now caught the attention of some strong Silicon Valley investors. Vinod Khosla has compared his firm’s investment in Oratomic to its early investment in OpenAI after Series A. Even Martin Mignot, partner at Index Ventures, agreed on the OpenAI comparison.
According to Dolev, Oratomic has another differentiating factor: an error-correction method it developed. It is a process that involves ensuring the components of a quantum system, known as qubits, behave correctly and deliver accurate results. He also said that the company thinks it can develop a meaningful commercial computer with only 10,000 qubits, far lower than the previous industry consensus of 1 million.
The funding will direct the company toward the remaining technical & engineering hurdles, and Oratomic’s computer is expected to be ready by 2030.
