In this episode of Venture Declassified, Mike Kelly and Jacob Schpok are joined by Grant Chapman, co-founder of Glassboard, along with GrowthX Partner Jeanette Renshaw for a candid conversation about what it really takes to build—and invest in—hard tech. Drawing from deep, hands-on experience across hardware, medtech, and physical product development, the group unpacks why hardware timelines routinely stretch, why testing and validation are chronically underestimated, and why optimism is often the most expensive line item in a founder’s budget. Jeanette brings a go-to-market and founder-coaching lens to the discussion, highlighting how early assumptions around customers, timelines, and revenue expectations often collapse once physical constraints enter the picture. Grant shares hard-earned lessons from working with founders who discover too late that physics, compliance, and manufacturing don’t bend to pitch decks, while Mike and Jacob ground the conversation in what angels should realistically expect when evaluating hard tech opportunities. Together, the group offers a clear-eyed look at how hardware startups can responsibly de-risk, raise capital without overpromising, and avoid the common traps that derail otherwise promising companies. For angel investors, this episode delivers practical insight into separating ambition from execution—and understanding when patience, not speed, is the real advantage.
