Horizon Quantum Computing: Funding, Investors & Team (Sep 2026)
Horizon Quantum Computing is pioneering classical to quantum programming: the automatic construction of quantum algorithms from conventional languages such as Matlab, Python or C. Spanning the entire chain from algorithm generation to hardware-specific implementation, its programming tools will allow users to develop quantum-accelerated applications whatever their expertise. Horizon Quantum Computing was founded in 2018 by Dr Joe Fitzsimons, a former professor and principal investigator at the Centre for Quantum Technologies in Singapore. The leadership team also includes Dr Si-Hui Tan, an active researcher in the field of quantum information science with over 15 years experience.
Horizon Quantum Computing has raised $126M across 3 funding rounds on record, the most recent an undisclosed round of $110M announced in Mar 2026.
That round is above the $7.5M median round size for Consumer Electronics companies tracked on FundedIQ over the last two years.

About FundedIQ's Horizon Quantum Computing Funding Data
FundedIQ tracks announced funding rounds and refreshes this profile every week. Round dates, stages and amounts are normalised to a single format, converted to US dollars, and de-duplicated: two records of the same round announced days apart are merged, and two genuinely different rounds are kept apart on the amounts they disclose. Amounts shown are the disclosed figures only — a round announced without a number is listed and excluded from the total rather than estimated.
Employee counts are reported bands, not exact headcounts. Founder and executive names carry the job title on record. Anything we do not hold for Horizon Quantum Computing is left off this page rather than filled in.
