Industrial Capabilities in Space
Adi Oltean, co-founder of Star Cloud, advocates for developing industrial capabilities in space, focusing on extracting raw materials and 3D printing structures on the moon. He highlights the efficiency advantages of lunar manufacturing and encourages related startups to apply to Y Combinator.
Summary
In this brief transcript, Adi Oltean introduces himself as the co-founder and chief engineer of Star Cloud, a company building data centers in space. He outlines a vision for establishing industrial capabilities beyond Earth, particularly on the moon and in deep space.
Oltean focuses on two core industrial processes he believes are promising for lunar development: the extraction of raw materials such as silicon, aluminum, iron, and titanium through electrolysis, and the 3D printing of complex structures using molten regolith. He argues that the latter process would be more efficient on the moon than on Earth, citing the absence of the need for structural supports during printing as a key advantage, likely due to lower lunar gravity.
The transcript concludes with Oltean extending an invitation on behalf of Y Combinator to entrepreneurs and startups working in the space industrial sector, signaling that this is an area of active investment interest for the accelerator.
About this episode
The moon has abundant silicon, aluminum, iron, and titanium, and extracting them there may actually be more efficient than on Earth. We want to see startups developing industrial capabilities in space, from electrolysis of raw materials to 3D printing complex structures from molten regolith. Apply to YC Summer 2026 at ycombinator.com/apply.
Key Insights
- Adi Oltean argues that 3D printing complex structures from molten regolith on the moon would be more efficient than on Earth because of the lack of supports needed during the printing process, likely enabled by lower lunar gravity.
- Oltean identifies silicon, aluminum, iron, and titanium as the key raw materials to be extracted on the moon via electrolysis, framing material extraction as a foundational step for space industrialization.
- Oltean positions Star Cloud, a space-based data center company, within a broader vision of deep space industrial development, suggesting that data infrastructure and physical manufacturing are complementary pillars of the space economy.

[0:00] Hi, I am Adi Oltean, co-founder and chief engineer at Star Cloud, building data centers in space. The broad idea I would like to see is developing industrial capabilities on the moon and in deep space, particularly extracting raw materials such as silicon, aluminum, iron, and titanium through electrolysis and 3D printing of complex structures from molten regolith on the moon, which should be more efficient than on Earth due to lack of supports. If you are working on something like that in the space, then Y Combinator would like to hear from you.

How To Pick A Startup Idea
YC partner John argues that founders should stop overthinking startup ideas and instead commit fully to a single idea, going deep on customer understanding. He presents a rubric for validating ideas through immersive customer research and outlines three qualities of strong AI-era startup ideas. He emphasizes that even failed deep dives produce valuable data and often surface better underlying opportunities.
Groww: If Your Customers Don't Love It or Hate It, You've Already Lost
Lalit Keshre, co-founder of Groww, discusses the company's journey from a failed robo-advisor to India's largest investment platform, emphasizing customer obsession, radical transparency, and organic growth. He shares how Groww achieved product-market fit within 10-15 days of launching their revamped product in May 2017 by showing all investment products with full transparency. The conversation covers co-founder alignment, navigating regulation, and how AI is lowering barriers to building consumer products.
5 Papers That Show Where AI Research Is Heading Right Now
A research meetup covering five AI topics: protein language model scaling laws (ESM Cambrian), self-play for LLMs (SGS algorithm), streaming RAG for voice agents, formal verification with Lean, and agentic software engineering workflows. Presenters demonstrate how foundational AI scaling principles are transferring into biology, mathematics, and production engineering.
How Meesho Became India’s Biggest Shopping App
Vidit Aatrey, co-founder of Meesho, discusses the company's evolution from a local fashion marketplace to India's largest shopping app with 250 million annual buyers. He explains how customer obsession drove multiple pivots, including abandoning their successful WhatsApp-based social commerce model to launch a direct consumer app in 2021. He also shares how AI is now the next frontier for reaching the remaining 750 million potential Indian consumers.
The CEO Must Be the Chief AI Officer
Pedro Franceschi, co-founder and CEO of Brex, discusses how his company has gone deep on AI adoption, from personal use of Claude to enterprise-wide deployment of AI agents. He argues that CEOs must personally lead AI transformation, treating it as a company-wide refounding rather than a departmental initiative. The conversation covers AI agent security, token spend management, customer world models, and the broader philosophical shift required to build companies in an AI-native way.
