## Questions

### Who makes investment decisions at Longwall Ventures?

Investment decisions are made by the partnership, led by managing partners David Denny and Matthew Frohn, with partner Michael Penington. All three have direct operating experience inside Oxford University Innovation, the university's technology transfer office, prior to founding Longwall in 2010.

### How does Longwall source its deal flow?

The firm's deal flow is overwhelmingly sourced from UK research universities and government laboratories. The partners' background inside Oxford's tech-transfer office — and the firm's proximity to the Harwell Science and Innovation Campus — provides early visibility into spinouts that have not yet engaged with traditional venture capital. Longwall also works directly with the Science and Technology Facilities Council to identify commercial opportunities emerging from national labs.

### Which sectors does Longwall explicitly avoid?

Longwall does not invest in consumer internet, pure-play software-as-a-service, or financial technology unless there is an underlying hard-science or engineering moat. The firm's mandate requires a defensible link to university research, which fundamentally excludes asset-light consumer businesses and most B2B software startups. Life sciences, advanced materials, robotics, and clean-energy hardware form the bulk of the portfolio.

### How is Longwall connected to the British Business Bank?

Longwall has previously raised capital through the Enterprise Capital Funds programme, a British Business Bank initiative that matches government funding with private commitments to back early-stage UK technology companies. This structure allows Longwall to deploy patient government-linked capital alongside private limited partners, a funding mix that aligns with the firm's long-duration, research-heavy investment profile.

### What is Longwall's posture on follow-on funding?

The firm maintains reserves for follow-on investments in its highest-conviction portfolio companies, aiming to participate pro-rata in subsequent rounds. However, Longwall operates on a fund structure, not an evergreen vehicle, so reserve allocation is finite and decided by the partnership on a case-by-case basis. The firm frequently co-invests alongside later-stage funds such as Oxford Sciences Innovation for companies graduating out of its initial seed position.
