The Century of Material Science
A concentrated, long-only investment thesis on the semiconductor and AI-hardware stack powering artificial intelligence, robotics, and the next generation of quantum computing.
Explore the ThesisEach technological revolution made capability dramatically cheaper and more abundant. Semiconductors are not a bubble — they are this era's steam engine: the hardware that powers everything built on top of it.
Water and steam mills made goods cheaper and production far higher volume. Hardware defined the era.
RealizedMoore's Law — twice the power, half the cost, every two years. Silicon became the foundation of modern commerce.
RealizedCompute becomes the scarce input. Every model runs on physical hardware — GPUs, memory, and power silicon. Hardware leads software.
ActiveA new class of chips changes science itself — beginning in drug discovery, encryption, and materials science. Too early to own, not too early to track.
EmergingCrystallum Capital operates two distinct strategies — both anchored in the same PhD-level materials science expertise, structured separately to match the liquidity profile of each opportunity set.
A concentrated, long-only portfolio of ~15 high-conviction semiconductor and AI hardware names. Sized by forward growth, not market cap. Rules-based risk management with real-asset ballast.
Direct pre-IPO positions, SPV co-investments, and fund exposure with underlying semiconductor and AI hardware exposure. The same analytical edge applied where information asymmetry — and potential return — is highest.
~15 high-conviction names. Deliberate weights sized to forward growth, not market cap.
Compute, memory, and equipment leaders, plus ASML and TSMC — the irreplaceable chokepoints of global semiconductor supply.
Gold, copper miners, rare earths, and short-term treasuries. ~15% allocation to compress tail risk while preserving upside.
Pre-committed drawdown rules. Single position down 15%: trim by 50%. Portfolio down 20%: apply index puts.
The portfolio is built around the irreplaceable nodes of the AI hardware stack. Every AI model, every data center, every autonomous system runs on chips. We invest where value is created first: in the silicon and the materials beneath it.
Target weights. Illustrative only. Not investment advice.
Direct positions in late-stage private semiconductor and AI hardware companies ahead of public listing. PhD-level diligence on technology readiness and fab economics.
Special purpose vehicles providing targeted exposure to single private companies or assets with underlying semiconductor supply chain relevance.
Select positions in private funds with concentrated AI hardware or semiconductor exposure — diversified access to the private market opportunity set.
Distinct vehicle from the public equity SMA. Separate terms, minimums, and investor eligibility. Accredited investors only.
The same analytical edge that drives the public equity strategy — PhD-level understanding of which technology roadmaps are real versus aspirational — is arguably more valuable in private markets, where information asymmetry is higher and generalist venture investors cannot evaluate the underlying science.

Prabhu B. Iyer founded Crystallum Capital to apply PhD-level materials science judgment to semiconductor equity investing — an edge that generalist analysts cannot replicate from a spreadsheet.
As a Process Support Engineer IV at Applied Materials, he has a ground-level view of semiconductor fabrication economics, supply chain dynamics, and which technology roadmaps are real versus aspirational. His work has contributed to over $140M in commercial impact in defect review for a major semiconductor client.
His scientific training provides structural analytical depth when evaluating the companies building the physical infrastructure of AI. The investment thesis at Crystallum is not a financial model imposed on an unfamiliar industry — it is built from the inside out.
Prabhu is completing his Executive MBA in Finance at the Wharton School, where he works with senior finance faculty on the investment framework underlying the strategy.

Crystallum Capital is a business. But the work, for me, is also part of something larger — obligations I carry toward the country and institutions that made my success possible.
"The Western world gave me — an immigrant building something from the outside — openness, fairness, and a genuine chance to succeed."
Many people from my background are skeptical of Western institutions, and history gives them reason. My experience has been different. The United States and the broader Western world treated me with openness, fairness, and genuine kindness. The colleagues, partners, and institutions I encountered gave me every reasonable chance to succeed.
My work is, in part, an attempt to give something back to the culture and institutions that made it possible.
