Prior to its historic public listing, Horizon Quantum fortifies its leadership with IT veterans.
Horizon Quantum Holdings Ltd. (“Horizon Quantum”), a pioneer in the development of software infrastructure for quantum applications, has announced many notable appointments to its board of directors and senior leadership team. As it gets closer to a final merger with dMY Squared Technology Group, Inc. (“dMY”), which would see Horizon Quantum become a public company, these strategic actions are intended to strengthen the business’s governance and operational capability.

A Strong Board for the Quantum Age
After the “Business Combination” with dMY is completed, Horizon Quantum anticipates appointing four notable leaders to its board of directors as it gets ready for its next stage of expansion. The candidates reflect worldwide technical leadership and knowledge from successful enterprises.
Danielle Lambert, a contender, was Apple Inc.’s Vice President of Human Resources and helped build the iPod, iPhone, iPad, and retail operations teams. Apart from Apple, Lambert advised and invested in Nest Labs Inc. before Alphabet Inc. bought it.
She’s joined by Grab’s CFO Peter Oey. Having held key finance positions at Activision Blizzard Inc. and served as CFO of LegalZoom.com Inc. before its IPO, Oey has extensive expertise guiding businesses through major financial shifts.
The board will also gain from the experience of Jill Turner, who is now Broadcom Inc.’s chief human resources officer. Turner, who has over 20 years of experience leading human resources departments at Fortune 500 firms including Honeywell International and Lumen Technologies, is anticipated to offer crucial advice on growing Horizon’s worldwide staff.
Harry You, the current Chairman of dMY Squared, completes the board appointments. You have experience in the public markets, having previously held the position of lead independent director at IonQ Inc., a well-known maker of quantum gear, and as CFO for both Oracle Corporation and Accenture.
Boosting the C-Suite
Horizon Quantum has appointed Catherine Fitzsimons as Chief Legal and Compliance Officer, EVP of Strategic Initiatives, and Company Secretary in May, in addition to the board nominations. Fitzsimons was formerly the Head of Global Product Legal at Fidelity International Ltd., where he is presently the Director of Strategic Initiatives.
Fitzsimons’ legal background, especially at a business like Fidelity, makes her a “outstanding addition” who will serve as a superb steward for the company’s new public shareholders, according to Harry You, who expressed great trust in her. Fitzsimons herself stated that this is a “compelling opportunity” to lead the company through its change due to the present momentum in the quantum sector.
The Path to Open Marketplaces
The impending merger with dMY Squared Technology Group is directly responsible for the leadership growth. A $110 million PIPE (Private Investment in Public Equity) deal supports this merger. On February 17, 2026, the registration statement for this merger went into effect, which was a major regulatory milestone for the business.
The CEO and founder of Horizon Quantum, Dr. Joe Fitzsimons, stressed that “unlocking the full potential of quantum computers” depends on these appointments. Since its founding in 2018, the business has developed into a pioneer in quantum software infrastructure from a research-focused startup.
Innovation and Technological Milestones
The goal of Horizon Quantum is to close the gap between sophisticated quantum hardware and useful applications. The company’s main product, Triple Alpha, is an integrated development environment that allows developers to construct hardware-agnostic quantum applications utilizing many layers of abstraction.
On December 2, 2025, the firm made history by becoming the first quantum software company to own and run a quantum computer at its Singapore headquarters. Horizon’s software tools, such as Beryllium, a high-level, object-oriented language for quantum programming that made its debut in late 2025, are tested on this functional system.
Additionally, through a strategic partnership with Alice & Bob, the business is aggressively seeking quicker routes to fault-tolerant computing, concentrating on simplifying the implementation of cutting-edge quantum software.
A Disciplined Future
The emphasis is still on cautious expansion as Horizon Quantum gets closer to making its debut on public platforms, either the New York Stock Exchange or Nasdaq. The business must use the money from the PIPE deal to expand its operations, and it must contend with both technological and competitive obstacles, such as the difficulties of running its own quantum processor.
With a new legal head from Fidelity and a board made up of seasoned executives from Apple, Grab, and Broadcom, Horizon Quantum seems well-positioned to handle the shift from a private pioneer to a public leader in the emerging quantum economy.
