Frequently asked questions

How does Quantum Exponential source its deal flow?

The firm identifies and engages with over 100 high-potential quantum technology startups annually through a combination of direct sourcing and a partnership with Notion Capital, which uses a proprietary digital sourcing technology that applies heuristics to signals from multiple public and internal data sets to identify candidates aligned with Quantum Exponential's strategy.

Does Quantum Exponential operate as a single family office or a venture firm?

Quantum Exponential is structured as an asset manager focused on private equity in quantum technology. It is not a family office. The firm deploys capital into early-stage companies with the intention of co-leading follow-on rounds and taking an active role in business operations, resembling a specialist venture capital manager.

What investment stages does Quantum Exponential target?

The firm focuses on seed-stage funding with second-stage funding plans in preparation. For each investee company, Quantum Exponential intends to deploy initial capital and then co-lead the next funding round, indicating a strategy that spans pre-seed through Series A.

Which sub-sectors of quantum technology does the firm invest in?

The firm invests across quantum communications, quantum sensing, quantum metrology, and quantum computing software and components. Its portfolio includes companies working on quantum encryption, photonic integrated circuits for medical imaging, single-photon networking, silicon-based quantum computing, gas-imaging lidar, and superconducting quantum hardware.

Does Quantum Exponential have a geographic restriction on its investments?

The firm states it builds a portfolio of quantum technology companies within NATO-aligned countries. Its sourcing network covers the Americas, Europe, and Asia, and its portfolio includes UK-based spin-outs from the universities of Sussex, Sheffield, Bristol, Birmingham, and Glasgow, as well as a Nasdaq-listed company.
