In this episode of Family Office Investing Podcast & Investor Insights | Arthur's Round Table, Arthur Bavelas sits down with Elizabeth McCalley, founder of Start Stack, to explore one of the biggest mistakes founders make: Building a product is not the same as building a company. Elizabeth spent approximately 15 years at IBM before working with companies including Workday and Salesforce. Across sales, strategy, product management, commercialization, and enterprise technology, she developed a deep interest in taking new ideas into markets and figuring out what customers will actually buy. Today, Start Stack focuses on the often-overlooked period between having an idea and achieving product-market fit. AI has dramatically reduced the cost and difficulty of building software and launching products. But Elizabeth argues that easier building creates a new danger: Founders can now build the wrong thing faster. The fundamental questions haven't changed: • What problem are you solving? • Who actually cares? • Who will pay for it? • What market are you serving? • How will you acquire customers? • Do the economics work? Elizabeth describes Start Stack's roughly 45-step business-planning methodology, covering company purpose, market strategy, resource planning, commercialization, and an investable business plan. A key philosophy is: The founder does the work. AI supports the process. Rather than generating disconnected reports, the goal is a coherent business where product, market, financial assumptions, buyers, resources, and go-to-market strategy all fit together. Arthur and Elizabeth also discuss the hidden cost of startup pivots. Elizabeth says pivots can cost roughly $40,000 to $500,000, making earlier validation potentially one of the highest-return investments a founder can make. They also explore how the same structured information could eventually help investors perform faster, more standardized early-stage diligence. What You'll Learn • Why product creation and company building are different • How founders can validate demand earlier • Why AI does not replace commercialization • How to reduce expensive startup pivots • Why disconnected AI reports can create false confidence • How better planning reduces marketing waste • Why corporate executives often underestimate entrepreneurship • How investor diligence may become more efficient About Elizabeth McCalley Elizabeth McCalley is the founder of Start Stack and a commercialization specialist whose career includes IBM, Workday, Salesforce, enterprise technology, sales, strategy, product management, and go-to-market execution.

It has not eliminated the need to know what is worth building. #Startups #Entrepreneurship #ArtificialIntelligence #ProductMarketFit #StartupStrategy #FamilyOffice #VentureCapital #Founder Educational discussion only.
