Inside Deep Tech Investing: A Masterclass From Both Sides of the Table | Graeme Harrison

What if AI's binding constraint isn't smarter models or faster chips - but the megawatts sitting unused inside regulated utilities in every major city?Graeme Harrison, General Partner at Augur VC and Founder & CEO of Simply Silicon, has spent years betting that energy, not compute, is the real bottleneck for AI. Augur was incubating against an "energy AI" thesis before the term "NeoCloud" existed. Simply Silicon, the operating company that emerged from Augur's dealflow, is now building the world's first air‑gapped inference networks for major North American cities - a category of one, for now.Their first site is a regulated district heating plant in downtown Calgary with 12 MW of unused electrical capacity - the kind of deal Silicon Valley money alone could never close. On the fund side, Augur has been first into companies like Beyond Reach Labs (cold‑emailed pre‑demo‑day for an uncapped SAFE), Aero Volta, and Cumulus, underwriting outliers against a worldview Graeme calls "technological determinism."Graeme spent nearly a decade doing technology M&A at Bennett Jones in Canada before launching Augur. He built his first company - Quest Websites - in mid‑90s Saskatchewan as a kid, got wiped out years later on an electronic cigarettes import business when a regulatory change seized his inventory, and went to law school to learn the commercial backbone of how the world actually runs. In 1999 he read Ray Kurzweil's The Age of Spiritual Machines, and that book has quietly directed every choice he's made since. In this episode, we explore:- Energy as the Binding Constraint: Why the AI infrastructure race is going to be won by whoever solves power, not compute.- The Cold Email to Beyond Reach Labs: How Augur wrote an uncapped SAFE before demo day and why the founders said yes.- Technological Determinism: Augur's underwriting model - civilizations unlock technologies in a fixed sequence, and the next ones are knowable.- "The Internet Wasn't Built for This": Why current data center architecture can't deliver what regulated enterprises need from AI inference.- The Calgary District Heating Deal: How Simply Silicon co‑locates inside a regulated utility - and why Silicon Valley capital alone can't open that door.- The Death Spiral of Venture Capital: Why generalist VCs reject the deals worth doing, and what conviction‑led underwriting looks like instead.- Don't Die: The Y Combinator rule Augur leans on through portfolio inflection points - and the "teardrop" founder who said no to an early acquisition.- Plus a cameo from Mikey: hired into Augur at 18, now running investor tours at Simply Silicon at 20.Learn more about Graeme:https://deeptech-decoded.com/guests/graeme-harrisonTimestamps:0:00 - Designing the conversation: identity, two roles, Beyond Reach1:05 - Ten years of tech M&A at Bennett Jones2:03 - The electronic cigarette business that wiped him out4:59 - From Quest Websites to law school: learning how the world runs7:16 - Wearing two hats: Augur VC and Simply Silicon9:27 - Ray Kurzweil and the energy‑AI North Star10:43 - Dan Chapman and building the Augur team13:43 - Technological determinism and the Kardashev scale17:23 - The Beyond Reach Labs investment story22:11 - The cold email that became an uncapped SAFE24:35 - $325M in LOIs by demo day25:17 - What was actually on the investment memo27:47 - Investing vs. building: which would Graeme pick?29:44 - Simply Silicon emerges from Augur's dealflow31:31 - Why the internet wasn't built for AI inference36:00 - Recruiting an inference engineer out of AMD40:09 - Inside the Calgary district heating plant deal44:52 - What makes founders pick Augur over bigger checks47:30 - The "teardrop" founder who said no to an acquisition50:49 - Don't die: Y Combinator's most important rule57:00 - Token‑maxing, patent‑maxing, and broken VC incentives1:02:45 - Spotting an 18‑year‑old outlier1:13:00 - The book that gave Graeme his North Star

Football Field Size Solar Arrays That Fold Into a Rocket | Pele Collins, Beyond Reach Labs (YC W26)

What if the biggest structures humans ever build aren't on Earth - but folded into a backpack and unfolded 50x larger in orbit?Pele Collins, co-founder & CTO of Beyond Reach Labs (YC W26), is on a mission to become the "big builder" of space. Their flat-pack origami mechanism delivers solar arrays up to 100 meters long, 88% cheaper than today's ISS-grade solutions — and it gets stiffer as it gets bigger, solving the floppy-array problem that limits satellite movement. Pele spent five years at SpaceX as the responsible engineer for the Dragon parachutes, led plasma-facing components at Commonwealth Fusion, returned to SpaceX to set up parachute manufacturing, and in October 2025 joined his Penn classmate Mitchell Fogelson — fresh from a CMU PhD on kilometer-scale NASA structures — to build Beyond Reach Labs.In this episode, we explore:- The 88% Cheaper Mechanism: A stamped-metal, flat-pack design that beats a $100M composite roll-up tube.- From Dragon Parachutes to Space Origami: Pele's path from SpaceX recovery hardware to deployable space structures.- "The Best Deployable Is No Deployable": Why simple wins in orbit — and why James Webb spooked the industry.- Bigger = Stiffer: The natural-frequency trick that flips the physics of large solar arrays on its head.- 2001: A Space Odyssey, But Real: The kilometer-scale, centripetal-gravity station behind the whole mission.- Vomit Comets and Tracking Dots: How you actually prove a deployable will work before sending it to orbit.- The Pivot That Saved the Company: From selling a simulation tool to designing and building the hardware itself.Learn more about Pele:https://deeptech-decoded.com/guests/pele-collinsTimestamps:0:00 Why Beyond Reach is more than what it looks like - meet Pele Collins1:25 South Africa → Penn → SpaceX: Pele's human-being introduction3:50 Legos, robotics, and the path to mechanical engineering5:07 Mr. Thompson, Mr. Bradley, and the physics teachers who set off a career8:00 Sports, soccer, and being named after Pelé9:30 Immigrant mentality - secure the basics, then take the swing12:18 Mitch Fogelson, NASA kilometer-scale structures, and founding Beyond Reach13:30 Y Combinator - and the treadmill since14:18 The space-economy explosion - and why James Webb is the inspiration17:18 The ISS took 80 launches - there has to be a better way22:43 Why solar arrays are the bottleneck of the space economy23:10 Floppy panels, first natural frequency, and why bigger is harder25:14 Thermal radiators and the heat problem of orbital data centers26:03 "The best deployable is no deployable" - the deepest law of space hardware28:00 88% cheaper than ISS-grade solar - the simple-is-best approach31:39 The $100M composite roll-up tube - and why it's overkill32:56 Silicon vs. triple-junction - the material trade-off bigger arrays unlock34:08 Where Beyond Reach is right now - prototypes, customers, milestones35:56 The first dedicated launch - early 202737:14 What keeps a parachute engineer up at night39:21 Testing in the Vomit Comet - zero-gravity flights with tracking dots40:25 Day one with a customer: how Beyond Reach designs to spec41:35 The 100-meter array, 150kW, and the limits of stiffness43:39 In love with the problem, not the solution44:28 Retractability - figure-skater physics for satellites46:58 The aha moment: customers wanted the hardware, not the software48:54 Patents vs. execution - why moving fast still wins50:01 Cameron's AMA - how big can Beyond Reach actually get?52:14 Legos, Meccano, and why the simple solution always wins

Moon Hotel Trojan Horse: 1st Bricks of a Type III Kardashev Civilization | Skyler Chan, GRU Space

The space industry is currently addicted to the "tourism" narrative, but if we’re being honest, tourism is just the flywheel. The real game isn’t about who puts the first billionaire in a lunar suite - it’s about who owns the infrastructure that makes Earth’s gravity well irrelevant. Skyler Chan thinks the moon isn't a destination, it's the ultimate physical moat.In this episode, we’re sitting down with Skyler Chan, the founder of GRU Space (Galactic Resource Utilization). We talk about the "Promethean moment" of off-world manufacturing and why Skyler is making the provocative case that to reach a Type III Kardashev Civilization, we have to stop "shipping Earth to space" and start building the moon with the moon.From the physics of the "Mars Moat" to the literal first man-made bricks on the lunar surface, this is a deep dive into the industrialization of our solar system.What’s inside:– The Trojan Horse: Why the Moon Hotel is actually a beachhead for an intraplanetary construction empire.– Stealing the Moon: The origin of GRU and the cold economics of Galactic Resource Utilization.– The Kardashev Shortcut: Why Skyler is working backward from Type III while we’re still stuck at Type 0.7.– The First Lunar Bricks: Why the first physical product made on the moon is the most critical path in human history.– The Mars Moat: Why the first colony to sustain life creates a geopolitical power Earth can’t touch.– The "Start Now" Mindset: Why the "deferred life plan" is a trap and why Skyler went all-in at 21.About Skyler Chan & GRU Space: Skyler is building the foundational infrastructure for an interplanetary species. By focusing on lunar soil (regolith) and automated manufacturing, GRU Space is trying to de-risk the survival of consciousness by moving us past Earth’s resource limits.Learn more about Skyler:https://deeptech-decoded.com/guests/skyler-chan [https://deeptech-decoded.com/guests/skyler-chan]0:00 Skyler introduces himself: from astronaut dream to lunar habitation2:04 Why making humanity planetary is an existential calling4:27 "Imagine investing in the foundations of New York City"6:44 Starting the Mars Habitat Club at Berkeley9:00 How "Gru Space" got its name (Galactic Resource Utilization → "steal the moon!")11:04 The medieval king lives a worse life than you14:02 The 4 problems that will kill you on the Moon18:02 "The hotel is just the beachhead" - the real master plan22:14 Companies already want their logos on the Moon bricks25:00 Making humanity planetary is an execution problem, not a tech one29:04 Partnerships, collaborators, and the road ahead32:02 Why academic circles will never solve this36:00 The brick-making machine: 6 weeks to prototype39:04 Why lunar caves won't work and the materials approach42:15 Building the team and finding the right people43:58 "What's your team culture?"
