SandboxAQ is an Alphabet spin-out positioned at the convergence of AI, quantum-inspired computation, and national-scale digital infrastructure. With roughly $950M raised and a valuation around $5.75B as of April 2025, it is one of the most heavily capitalized private players in post-quantum cryptography, quantum sensing/navigation, and physics-level simulation. The companyâs LQMs on Google Cloud and joint work with Nvidia in drug discovery give it credible technical and commercial hooks in life sciences and finance, while deployments of its AQtive Guard platform and sovereign partnerships with entities such as Saudi Aramco and Bahrainâs Mumtalakat extend reach into cybersecurity and national infrastructure. SandboxAQâs strategy of delivering software-first, hardware-agnostic âAQâ solutions into highly regulated, high-value verticalsâbacked by blue-chip investors and cloud/silicon partnersâpositions it as a differentiated platform bet for the coming decade of post-quantum security and AI-accelerated scientific and financial computing.
