What Horizon Quantum does

Horizon Quantum is a Singapore-headquartered quantum-software company building a hardware-agnostic development environment that allows developers to write quantum-accelerated applications without managing the underlying qubit hardware. Its core platform, the Triple Alpha IDE, is paired with a proprietary quantum-native language called Hyperion that compiles code to run on more than 30 supported quantum hardware backends spanning superconducting, trapped-ion, and photonic modalities. The platform also includes Beryllium, a public cloud-accessible API and compiler, and Ember-1, a tool that automatically synthesizes optimized quantum circuits for custom chip architectures.

The company's commercial strategy is two-pronged. First, it intends to monetize developer and enterprise access to the Beryllium cloud API on a usage-based pricing model, with tiered subscription plans targeting enterprise quantum-computing teams, academic research groups, and independent developers. Second, it intends to capture a share of the hardware-design automation market through Ember-1, which is sold to quantum hardware manufacturers. As of Q1 2026 the company is pre-revenue, with Triple Alpha offered as a free beta and Beryllium just entering the market following the company's Nasdaq debut via SPAC merger with dMY Squared in March 2026.

Horizon Quantum serves three customer segments: enterprise R&D teams in finance, pharmaceuticals, and logistics exploring quantum advantage for optimization and simulation workloads; academic and government research institutions; and quantum hardware vendors seeking compiler and circuit-design tooling. The company has approximately 100 employees, with a leadership team anchored by founder Joe Fitzsimons (Oxford PhD in quantum information) and operating from offices in Singapore, Dublin, and remote locations.

Revenue model

1. Usage-based pricing (planned): Company has stated it will generate revenue through usage-based pricing on deployed Triple Alpha APIs once 'real quantum advantage' emerges and demand for quantum processing materialises. As of Q1 2026 the company was pre-revenue.
2. Enterprise / consulting software pre-revenue: CEO has explicitly stated the company is prioritising technology development over near-term revenue generation and is not pursuing consulting-style work, meaning no meaningful commercial revenue stream existed as of Q1 2026 despite the public-company transition.

Core offering

Horizon Quantum fundamentally builds a hardware-agnostic quantum software development platform centered on its Triple Alpha IDE. The platform lets developers write quantum programs in three proprietary languages (Beryllium, Helium, and Hydrogen) that compile down to instructions for diverse quantum hardware modalities, eliminating the need to rewrite code when targeting different quantum processors. The company complements this software stack with its own Ember-1 quantum hardware testbed in Singapore for debugging and validation.

Product overview

Horizon Quantum offers a single unified quantum software development platform anchored by Triple Alpha, its hardware-agnostic integrated development environment (IDE), built on three interlocking software infrastructure layers: the Development Infrastructure (containing the IDE, proprietary programming languages, and optimizing compiler), the Deployment Infrastructure (cloud-first REST API deployment), and the Execution Infrastructure (runtime for complex control flow, currently in development). Triple Alpha's core capabilities include Subroutines from C, Code Portability, and Turing Completeness, while advanced capabilities include Program Optimization, Measurement-Based Quantum Computation, Dynamic Memory Management, and Pulse Control. The platform supports multiple proprietary programming languages (Beryllium object-oriented, Helium BASIC-like, and Hydrogen assembly-like) plus a Hardware layer supporting native instruction sets like OpenQASM and Quil. Complementing this software stack, Horizon operates its own Ember-1 hardware testbed in Singapore (a 9-qubit superconducting system combining Rigetti, Quantum Machines, and Maybell components), with a second testbed planned for Dublin featuring a 256-qubit IonQ trapped-ion system. The platform integrates with more than 30 backends including IBM, IonQ, IQM, OQC, Rigetti, AQT, and AWS systems.

Direct peers

• Quantinuum: Quantinuum (Honeywell + Cambridge Quantum) combines trapped-ion quantum hardware with a full quantum software stack including InQuanto and TKET — a vertically integrated peer that competes with Horizon in both the compiler and the broader enterprise quantum-software market.
• Strangeworks: Strangeworks offers a quantum computing platform that aggregates multiple hardware backends (IBM, IonQ, Rigetti, Quantinuum) behind a unified developer interface — directly competing with Triple Alpha's '30+ backends' value proposition for enterprise and developer customers.
• Classiq: Classiq builds a hardware-agnostic quantum software development platform with a high-level modelling language and compiler that automatically generates quantum circuits — directly comparable to Horizon's Triple Alpha IDE and Beryllium language stack, and serving the same enterprise developer persona.
• Xanadu Quantum Technologies: Xanadu builds photonic quantum hardware and the open-source PennyLane software stack for hybrid quantum-classical machine learning — a hardware-plus-software peer targeting developer-friendliness and cross-platform deployment similar to Horizon.
• Zapata Computing: Zapata AI (formerly Zapata Computing) provides enterprise quantum + classical workflow software (Orquestra) for chemistry, finance and materials applications, targeting the same pharma/finance vertical customers with hardware-agnostic abstractions.

Broad incumbents

• Microsoft Azure Quantum: Microsoft Azure Quantum offers the Q# language, QDK, and Azure cloud-hosted access to multiple quantum hardware providers — a broad incumbent whose hardware-aggregator model directly overlaps with Horizon's deployment infrastructure.
• Google Quantum AI: Google Quantum AI develops Cirq (open-source framework) and Willow/Heron quantum processors, focusing on error correction milestones — a broad incumbent whose open-source software strategy sets the competitive baseline for hardware-agnostic quantum IDEs like Triple Alpha.
• IBM Quantum: IBM Quantum bundles Qiskit (open-source SDK), Qiskit Runtime, and IBM Cloud quantum hardware into an integrated stack — a broad incumbent competing directly with Triple Alpha for quantum developer mindshare while also being a backend integration partner for Horizon.

Emerging players

• Q-CTRL: Q-CTRL provides quantum control infrastructure software (error suppression, performance management) that complements rather than replaces Triple Alpha — an adjacent peer whose software could be integrated into Horizon's execution infrastructure.
• QC Ware: QC Ware builds enterprise quantum and quantum-inspired algorithms and software (Forge) for finance, chemistry and optimisation — an emerging competitor targeting the same pharma/finance verticals with a more algorithm-services orientation.
