Haiqu
Haiqu is a quantum software company building a hardware-aware operating system that helps enterprise and scientific R&D teams run larger, more useful workloads on today's quantum computers - without waiting for fully fault-tolerant machines. Its full-stack platform combines agentic R&D tooling, an optimization SDK, and a runtime that the company says can cut quantum execution cost and time by orders of magnitude. Founded in 2022 and backed by an $11M seed round led by Primary Venture Partners, Haiqu works with early enterprise users including Capgemini, HSBC, BMO, Airbus, and Deloitte.
Richard Givhan
Richard Givhan is the co-founder and CEO of Haiqu, a quantum software company building a hardware-aware operating system that squeezes useful results out of today's noisy, qubit-starved quantum computers. A Stanford-trained engineering physicist who once chased dark matter at the Kavli Institute, Givhan now bets on the unglamorous middleware layer - circuit optimization, error shielding, and orchestration - to make near-term quantum applications run at roughly 100x lower compute cost. Incubated in 2022 inside Toronto's Creative Destruction Lab Quantum stream, Haiqu has raised about $19 million to date, including an $11 million seed round in January 2026 led by Primary Venture Partners.
