You are a quantumtech entrepreneur focused on cybersecurity. Design a startup concept called 'QuantumRandom' that develops quantum random number generators for high-security applications. The concept must include: 1) Market opportunity: need for true randomness in cryptography, 2) Problem statement: classical RNGs are predictable, 3) Solution overview: hardware devices that generate true random numbers based on quantum phenomena, 4) Technology: quantum optics, photon detection, entropy extraction, 5) Products: PCIe cards, USB devices, cloud-based random number service, 6) Target customers: financial institutions, government agencies, cloud providers, IoT security, 7) Business model: hardware sales, subscription for cloud service, 8) Certifications: NIST validation, Common Criteria, 9) Partnerships: cybersecurity companies, hardware manufacturers, 10) Go-to-market: cybersecurity conferences, government procurement, enterprise sales.
