Company Facts
IPO Status
No IPO announced
Quantum Machines shares are not available on public exchanges. See below for listed alternatives with similar technology.
Quantum Machines doesn't build qubits — it builds the control and orchestration layer that runs on top of nearly every qubit modality on the market. Its Quantum Orchestration Platform (QOP), delivered through OPX+ and OPX1000 hardware controllers plus software, handles pulse-level qubit control, readout, real-time calibration and error correction for superconducting, trapped-ion, neutral-atom and spin-qubit systems alike. As of its 2025 funding round, the company said its technology was used by more than half of all companies building quantum computers — a "picks and shovels" position that makes it agnostic to which hardware architecture ultimately wins.
Founded in Tel Aviv in 2018 by Itamar Sivan, Yonatan Cohen and Nissim Ofek, Quantum Machines closed a $170 million Series C in February 2025 led by PSG Equity with Intel Capital and Red Dot Capital Partners, bringing total funding to roughly $280 million. It has active technical partnerships with hardware vendors including Rigetti and QuEra, and expanded its European engineering footprint through the May and June 2026 acquisitions of QHarbor and PCB Engineering, establishing a Budapest R&D hub.
| Round | Amount | Date | Key Investors | Valuation |
|---|---|---|---|---|
| Series C | $170M | Feb 2025 | PSG Equity (lead), Intel Capital, Red Dot Capital Partners | — |
| Earlier rounds (Series A-B) | ~$110M cumulative | 2018-2023 | Undisclosed early venture backers | — |
No listed pure-play matches the control-systems model directly. Quantum Machines partners technically with Rigetti (RGTI), and its OPX hardware runs underneath machines from many public and private hardware vendors — broad exposure is available via the QTUM ETF.
Can you buy Quantum Machines stock?
No. Quantum Machines is private and has not announced an IPO. It partners technically with Rigetti (RGTI), among other listed and private hardware vendors.
What does Quantum Machines actually sell?
Control and orchestration hardware and software (the OPX+/OPX1000 controllers and Quantum Orchestration Platform) that manages qubit control, readout and calibration for quantum computers — regardless of qubit modality. It does not build its own quantum processors.
How much has Quantum Machines raised?
Approximately $280 million total, including a $170 million Series C in February 2025 led by PSG Equity with Intel Capital and Red Dot Capital Partners.
