Nox Metals modernizes a huge metals market
Paige says Nox Metals is one of her fastest-growing portfolio companies: it is a next-day metal servicing platform between steel mills and downstream aerospace/defense manufacturers, addressing a $200B market with fewer than 40 software engineers employed in the industry.
Europe's Zurich tech is undercapitalized
Katelin offers a contrarian Europe view: US VCs are irrationally scared of regulation, and Europe, especially Zurich, Switzerland, is producing some of the best physics and quantum work in the world while remaining dramatically undercapitalized. She would rather back a rational-priced Zurich quant team than another US agent wrapper.
EU regulation creates compliance moat
Paige says heavy EU regulation creates a moat for startups willing to eat the frog and do compliance first. Her portfolio company Mezzo built its AI engine to work in the hardest regulatory environment so it can later expand into less regulated markets.
StarCloud orbital data centers are winning
Katelin made a non-consensus seed bet on StarCloud, which puts GPUs on solar-powered satellites and has now reached a $2.3B valuation with Nvidia and Cisco investing. She believes orbital data centers are made viable by collapsing launch costs and the team's audacity.
HGEN displaces natural gas with onsite hydrogen
Katelin reverse-engineered an infrastructure-for-the-inevitable investing framework and cites HGEN as an example: on-site hydrogen production for heavy industry that can take out natural gas and sits upstream of industrial re-shoring and energy bottlenecks.
Edge AI wins for sensitive factory data
Paige's 2024 multimodal AI thesis led her to back Manva, which runs local edge AI models on factory floors for quality assurance and safety. She believes edge AI is the future where sensitive data or compute constraints make cloud-only models unworkable.
More launch providers will win space
Katelin argues the US space economy should not be a SpaceX-only single point of failure. She believes multiple launch providers can win without catching SpaceX, and Stoke Space's fully reusable two-stage rocket is one such delivery-van beneficiary.
Vertical physical AI reaches revenue faster
Paige focuses on verticalized physical AI applications rather than general-purpose robotics because they reach revenue and commercialization faster and avoid the massive dilution of capital-intensive general-purpose platforms.
Top talent is now building physical AI
Katelin sees the physical AI and hardware boom as more than a bubble: the best engineers have shifted from ad tech to building rocket engines and hard tech, and hardware is now treated as a moat. She echoes Jensen's prediction that every industrial company will become a robotics company.
Build vertical on-prem LLMs, avoid labs
Jason argues startups built on Frontier Lab APIs risk being rug-pulled as labs face pressure to compete; the winning response is to build vertical open-source models on-prem, citing 11 Labs, Lovable, Figma, and Lora's legal vertical models.
