Episode 66: “Build vs Buy” | Black Prism Capital Partners Founder Steven Miller on Dual-Use Investing, Government Sales, and Deep Tech Diligence

Today's episode explores three ideas that caught my attention:

① Government demand is not the same as government revenue: Steven explains why “the government needs this” is not enough for an investor. A real dual-use thesis requires evidence of a buyer, a budget, a contracting path, and people inside the government who can execute.
② Commercial-first companies need a distinct government strategy: Selling to the federal government is a completely different sales motion. Steven shares why companies should not let a speculative government opportunity distract from their commercial growth, and why the right specialist can help build a separate federal pathway.
③ Investor diligence has to go beyond the pitch deck: From SBIR awards to high-profile advisory boards, Steven explains why surface-level signals can mislead investors who do not understand the government market.

Steven spent two decades building a government contracting company before launching Black Prism, a venture firm focused on commercial-first deep tech companies with credible dual-use potential. In this conversation, he shares how he thinks about government buying behavior, federal sales, AI security, early-stage diligence, and the signals investors should look for before backing a dual-use company.

During our conversation, Steven shares:

  • Why the government is increasingly looking to buy commercial technology rather than build it internally.

  • How to distinguish a real government customer from a vague government-market claim.

  • Why a Phase I SBIR award does not automatically create lasting revenue.

  • How Hardshell is approaching data security in the age of AI.

  • Why stacked advisory boards should be reference-checked, not simply admired.

  • Why selling to the federal government requires a separate sales motion.

  • The questions every angel investor should ask before underwriting a dual-use opportunity.
