From Lab to Scale: Tina Tosukhowong of TDK Ventures on What Makes Deep Tech Commercially Viable

Breakthrough science is only the beginning. The harder challenge is turning promising technology into a system that can operate reliably, economically, and repeatedly in the real world.In this episode of Green Giants: Titans of Clean Energy, Wes Ashworth, host and President of Lee Group Search sits down with Tina Tosukhowong, Investment Director at TDK Ventures, to explore what separates deep-tech companies that scale from those that stall between the lab, pilot plant, and first commercial facility. Tina brings an unusually valuable perspective to venture investing. Before becoming an investor, she spent years as a chemical engineer and industrial operator working across process development, pilot operations, scale-up, commercialization, manufacturing, and customer qualification.  That operating experience shapes how she evaluates climate tech, advanced materials, AI infrastructure, and other capital-intensive technologies today.Tina explains why scaling is not simply a matter of building a larger version of a successful pilot. At commercial scale, entirely new risks emerge around heat transfer, fluid flow, contamination, materials handling, uptime, permitting, utilities, feedstocks, safety, supply chains, and integration with customer sites. The companies that succeed are often the ones that identify failure modes early, run the right experiments, and learn faster than their capital disappears. The conversation also tackles one of the most important questions in deep tech: When has a company actually earned the right to scale?Wes and Tina explore why raising too much money too early can be dangerous, how founders should think about risk retirement before committing hundreds of millions of dollars to a first commercial plant, and why the strongest financing strategy aligns capital with specific learning milestones. They also discuss founder-market fit, coachability, executive hiring, productive board conflict, and why the right investor syndicate can matter as much as valuation. The discussion then moves into the rapidly evolving physical infrastructure behind AI. Tina breaks down opportunities across data-center power delivery, energy storage, cooling, thermal materials, networking, semiconductors, and photonics. She explains why the next wave of AI infrastructure innovation may come not only from better chips, but from everything required to power, connect, and cool them efficiently.  The episode also explores fusion energy, synthetic fuels, critical minerals, and frontier technologies, including Tina’s perspective on Type One Energy, INERATEC, and the growing overlap between clean energy, computing, advanced materials, manufacturing, and national supply-chain resilience. In this episode, you’ll learn: Why industrial scale-up exposes risks that laboratory success cannot predict  What founders should prove before committing to a first commercial facility  How capital discipline can prevent expensive first-of-a-kind mistakes  Why learning speed and coachability matter so much in deep-tech leadership  When experienced executives help startups and when they can slow them down  Why investor syndicates and boards become critical when plans break  Where Tina sees overlooked opportunities in AI data-center infrastructure  Why cooling, rack-level power conversion, and photonics could become major bottlenecks  What industrial operating experience reveals about the future of fusion  How e-fuels, critical minerals, AI, and advanced materials are increasingly converging For founders, investors, operators, and leaders building the next generation of clean energy and deep-tech companies, this episode is a practical look at what it really takes to move from possibility to commercial reality.Links: Tina Tosukhowong on LinkedInTDK Ventures WebsiteWes Ashworth: https://www.linkedin.com/in/weslgs/Email: [email protected]://leegroupsearch.com/green-giants-podcast/https://leegroupsearch.com/
