• Why Most Startups Fail: Founders Don’t Know What They Don’t Know Yet
    May 7 2026
    What if the real edge in building and investing in companies is knowing exactly where your knowledge stops? In this episode of Built Not Born, host Sage Nye sits down with Dave Fachetti, Partner at Venture Guides, to unpack the operator–investor mindset that drives durable outcomes. Drawing on decades of experience, Dave explains why great founders prioritize solving painful, urgent problems before optimizing execution, and how this “efficacy before efficiency” mindset underpins true product-market fit. He introduces his “know what you don’t know” test as a lens for evaluating founders, emphasizing self-awareness, curiosity, and coachability as critical traits. The conversation also explores cap table strategy as a long-term system, the importance of aligning all stakeholders, and why board dysfunction guarantees failure. Dave shares practical frameworks for hiring, leadership, and navigating AI opportunities, while highlighting the balance between conviction and listening. It’s a grounded playbook for founders and investors aiming to build resilient, high-performing companies.

  • The AI Hacker Era Is Here: Alissa Knight on Rewriting Cybersecurity
    Apr 2 2026
    What happens when a former teenage hacker builds AI that can find security vulnerabilities before attackers do? In this episode of Built Not Born, host Sage Nye speaks with cybersecurity expert, CAIO, Founder, and CEO of Assail, Alissa Knight, about the rapidly evolving intersection of AI and offensive security. Once arrested for hacking as a teenager, Alissa went on to build Ares, a powerful AI model that autonomously discovers vulnerabilities in APIs, mobile apps, and web applications. She explains why the age of adversarial AI means companies must shift from preventing attacks to continuously identifying weaknesses faster than attackers can exploit them. The conversation explores the rise of AI-driven security testing, the emerging “one-person unicorn” founder model, and how startups should think about hiring, fundraising, and defensibility in an AI-first world where directing intelligent systems may matter more than traditional expertise.

  • Why Your GPU Investments Are Running at 40% Efficiency, and How Zymtrace Fixes It
    Mar 18 2026
    What if your multi-million-dollar GPU investment was quietly delivering less than half its potential? In this episode of Built Not Born, the conversation focuses on why AI infrastructure performance often lags far behind spend, and how continuous profiling is emerging as a real competitive edge. Join host Sage Nye as she sits down with Israel Ogbole, CEO and cofounder of zymtrace, to explore why most GPU clusters run at just 20–40% utilisation, how traditional observability tools miss the real bottlenecks, and why profile-guided optimisation can unlock massive efficiency gains without demanding deep CUDA expertise. Israel shares hard-won lessons from building a must-have infrastructure product: validating real willingness to pay, avoiding “nice-to-have” traps, and navigating early founder dynamics. The discussion also dives into the growing talent gap in low-level systems engineering, and how rich profiling data can become context for LLM-driven optimisation workflows. It’s a practical, insight-dense conversation for founders, operators, and AI leaders focused on extracting real returns from AI infrastructure, not just scaling hardware.

  • Transforming physical product development with Brian Lindauer and VibeIQ
    Feb 17 2026
    What if your product development cycle could be compressed from 12 months to weeks? In this episode of Built Not Born, the conversation focuses on unpacking why physical product companies struggle to move fast and how they can build agility into their DNA. Host Sage Nye sits down with Brian Lindauer, Founder and CEO of VibeIQ, as Brian shares lessons from two decades across retail and product development, explaining how fragmented systems, unstructured data, and siloed teams quietly slow decision-making and inflate inventory risk. The conversation explores how true product-line understanding can compress development cycles from months to weeks, and why AI’s real power isn’t just automation, but prediction to help teams assess feasibility, margins, and manufacturability earlier in the process. Brian also dives into building enterprise tools people actually want to use, scaling go-to-market strategies for physical goods, and hiring A-players who thrive in ambiguity. It’s a practical, grounded discussion for founders and operators looking to turn product development from a bottleneck into a strategic advantage.

  • When the Internet Breaks: Building Infrastructure Resilience with Edward Tsinovoi
    Jan 15 2026
    What if a single internet outage could take down your entire business? In this episode of Built Not Born, the conversation unpacks a growing but under-discussed risk in modern infrastructure: edge fragility. Host Sage Nye sits down with Edward Tsinovoi, Co-founder and CEO at IO River, to discuss that as digital businesses scale, the risk of a single CDN outage can cascade into massive financial and operational damage. Edward draws on decades of experience in deep-tech infrastructure to explain why edge resilience has become mission-critical in 2026, and how multi-CDN strategies can be implemented without months of custom engineering. The conversation spans both technology and leadership, covering vendor lock-in, fault-tolerant system design, and the importance of decoupling edge infrastructure from application services. Edward also shares hard-earned lessons from building and scaling a deep-tech company, from assembling world-class teams to creating products that move from “nice-to-have” to truly indispensable.
