Frequently Asked Questions

Why is technical diligence so critical for early-stage deep tech investing?

Technical diligence is essential because the primary risk in deep tech is the potential for a scientific or engineering failure. Unlike businesses that primarily face market adoption risk, deep tech ventures must first prove that their underlying technology functions as intended, often at a scale that has never been achieved before.

What do investors mean by capital efficiency in the context of research?

Capital efficiency refers to the ability of a startup to reach key technical milestones while strictly managing its financial burn rate during the R&D phase. Investors want to see that researchers are maximizing the impact of every dollar spent on experiments, ensuring that a project remains viable even if it takes years to reach commercial status.

Why does the industry emphasize dual-use technology in recent years?

Dual-use technology is prioritized because it offers pathways to both commercial market expansion and government funding through defense or security applications. This versatility helps startups secure non-dilutive funding, which provides crucial operational stability while they continue to develop their core scientific offerings.

How does the due diligence process differ between traditional VC and deep tech VC?

Unlike traditional VC, which might place significant weight on user growth and viral metrics, deep tech VC focuses on the strength of patent portfolios and peer-reviewed methodology. Partners in these firms often hold PhDs or have specific research backgrounds that allow them to grill the technical team on the actual feasibility of the proposed technology.

What role do government partnerships play in funding high-stakes R&D?

Government funding acts as an early validator for companies working on projects that are too expensive or long-term for standard private venture capital. These partnerships often provide non-dilutive grant funding and early pilot opportunities that allow these companies to de-risk their technologies before eventually hitting the commercial market.

Are there specific sectors that VCs currently view as most promising?

While sentiment fluctuates, there is a consistent preference for infrastructure-heavy fields including energy transition, advanced semiconductor design, defense robotics, and synthetic biology. These sectors are favored because they address fundamental global needs and create assets that are difficult for new competitors to replicate.

Why are timelines for liquidity in deep tech typically longer?

Liquidations in deep tech are longer because the hardware and science-based R&D cycles are inherently resistant to rapid compression. Investors in these fields understand that building infrastructure that powers the rest of the economy requires significant time for testing, certification, and integration into existing global systems.
