Which VC Firms in Quantum Computing Are Right for Your Stage?

Whether you're raising an early round or preparing for an exit, it's important to speak with the right people. Here’s a brief look at the VC firms that invest in quantum computing companies at different stages.

Pre-seed and Seed VC Firms in Quantum Computing

Pre-seed and seed funding is the initial capital you'll raise to develop your core technology and find your first customers. For quantum startups, firms like San Francisco-based at.inc/ and Boston's Glasswing Ventures are active at this stage, as is the UNICEF Innovation Fund.

Early Stage VC Firms in Quantum Computing

Early-stage venture capital, typically Series A and B, helps you scale your team and accelerate growth once you have product-market fit. Many deep tech VC firms focus here, including Virginia-based Three Tree Ventures and Austin's Scout Ventures.
