SEEQC Files for Nasdaq IPO as SEQC: The Quantum Infrastructure Company Nobody Has Heard of But Probably Should

[Richard_36]

SEEQC, a quantum computing infrastructure company headquartered in Elmsford, New York, publicly filed a registration statement on Form S-1 with the SEC on June 29 for a proposed initial public offering on the Nasdaq Global Market under the ticker symbol SEQC. Cantor and BTIG are lead book-running managers, with Needham and Craig-Hallum also listed as underwriters. Share count and price range are not yet determined. The offering is being conducted alongside a merger with Allegro Merger Corp, with the merger expected to close substantially concurrently with the IPO.

SEEQC is doing something quite different from the pure-play qubit companies that have dominated quantum market coverage. Instead of building the qubits themselves, the company builds the digital control infrastructure that sits next to the qubits, specifically superconducting Single Flux Quantum chips and cryogenic CMOS electronics that handle control, readout and quantum-classical integration. The practical problem they are solving is that conventional room-temperature control electronics for quantum computers generate heat and create wiring bottlenecks that become catastrophic at scale. SEEQC's approach moves the control electronics into the cryogenic environment alongside the qubits, reducing power consumption to nanowatts while achieving gate fidelities exceeding 99.9 percent, results published in Nature Electronics. The company employs 42 people including 24 PhDs and operates its own superconducting foundry in an 8,100 square foot cleanroom.

Full year 2025 revenue was $4.2 million, up from $800,000 in 2024, with a net loss of $12.2 million. The company has partnerships across the quantum ecosystem and its foundry has been involved in CHIPS Act work to industrialise superconducting qubit manufacturing. For a sector where most companies are still selling access time to cloud-connected hardware, SEEQC is selling the picks-and-shovels layer that makes scaling even possible. If quantum hardware scales toward thousands and then millions of qubits, someone has to solve the control problem. This is the company betting it can be that someone.
