Quick Insights

Investors should prioritize the Re-industrialization of the U.S. by targeting firms that use AI to automate heavy infrastructure and electronics manufacturing. Focus on companies like Unlimited Industries that utilize Parametric Design to compress construction timelines, as this significantly boosts the Internal Rate of Return (IRR) for large-scale projects like Data Centers. Look for hardware startups using AI "compilers" to automate PCB design, a sector expected to reach full automation within the next two years. Monitor the Humanoid robotics space and firms applying Reinforcement Learning to physical engineering, as these technologies address the critical shortage of skilled manual labor. High-conviction opportunities lie in "vertically integrated" startups that own the entire project lifecycle rather than those simply selling software to traditional, resistant incumbents.

Detailed Analysis

Unlimited Industries

Unlimited Industries is an AI-native firm focused on vertically integrating the design, engineering, procurement, and construction of large-scale infrastructure projects (e.g., power plants, hospitals, data centers). • The company aims to automate the "Issued for Construction" (IFC) package—the massive set of instructions used by builders—which currently takes hundreds of engineers over a year to design manually. • Key Technology: They use a "model-led" approach where agents write code within a parametric framework to explore tens of thousands of design permutations instantly. • Vision: CEO Alex Moden predicts that in 10 years, all construction will be fully automated, moving from automated design to autonomous earth-movers and humanoids on-site.

Takeaways

Efficiency Gains: By compressing design timelines from years to months (or even button-clicks), the company significantly improves the Internal Rate of Return (IRR) for project investors. • Investment Theme: Look for "Vertical Integration" in heavy industries. Unlimited Industries suggests that to disrupt traditional sectors like construction, startups must own the entire process rather than selling software to resistant incumbents. • Risk Factor: The construction industry operates on a "stable return" incentive structure that resists new technology; success depends on aligning AI with project financing requirements.


Diode Computers

Diode Computers uses AI to automate the design and manufacturing of custom circuit boards (PCBs) within the United States. • Key Technology: They have built a "compiler" that allows AI models (like Anthropic's Claude) to write Python code to design hardware, rather than using traditional manual CAD tools. • Manufacturing: The company focuses on bridging the "80-20" automation gap. While robots already place most components, Diode aims to use AI to create "Design for Manufacturing" (DFM) outputs that allow for 100% robotic assembly without human intervention. • Open Source: Their core compiler toolchain is open-source (GitHub: dioding/pcb), aiming to become the industry infrastructure for hardware design.

Takeaways

Onshoring Opportunity: Diode is betting that AI-driven design can make U.S. manufacturing cost-competitive with Asia by reducing labor-intensive manual steps. • Timeline: The CEO believes specific subsets of electronics design will be fully automated within two years. • Investment Insight: The "Software-to-Hardware" bridge is a major growth area. By treating hardware design as code, Diode is tapping into the massive ecosystem of existing LLM coding capabilities.


Physical World AI & Robotics

• The discussion highlighted a shift from "bits" (software) to "atoms" (physical objects), focusing on how AI can manage physical constraints like fluid dynamics, heat, and electromagnetics. • Data Scarcity: A major bottleneck identified is the lack of "Common Crawl" style data for the physical world. Most high-quality design data is siloed within companies like Apple, Meta, or SpaceX. • Simulation vs. Intuition: AI is being trained via simulation to develop "intuition" or "taste," allowing it to predict if a design will work without running slow, expensive simulations every time. • Humanoids: While specialized robots (like pick-and-place machines) are currently more efficient, there is long-term bullishness on the Humanoid form factor due to the benefits of mass-manufacturing a single versatile design.

Takeaways

Sector Focus: Data Centers are a primary driver for these technologies. The massive demand for AI infrastructure is forcing the adoption of automated construction and modular hardware design. • Labor Trends: There is a critical shortage of skilled trades (electricians, manufacturing technicians). AI that "codifies" the knowledge of retiring experts is a high-value investment theme. • Actionable Insight: Investors should monitor companies applying Reinforcement Learning and Diffusion architectures to physical engineering problems, as these are the technical "moats" being built to solve data scarcity.


Key Investment Themes Mentioned

Re-industrialization of the U.S.: Using AI to regain the "muscle" of building large projects and manufacturing electronics locally. • Parametric Design: Moving away from "one-off" manual designs to systems where changing one variable (like the size of a lot or a component) automatically updates the entire engineering plan. • Incentive Alignment: The biggest hurdle to AI in the physical world isn't just technology; it's the "stage-gated" project finance world that needs to be disrupted by firms that can guarantee faster timelines.

Episode Description
Erin Price-Wright speaks with Alex Modon, cofounder and CEO at Unlimited Industries, and Davide Asnaghi, CEO at Diode Computers, about how AI is moving from software into the physical world. They discuss automating construction and electronics design, using code and simulation to model real-world systems, and how incentives and manufacturing constraints shape adoption. They also examine what it takes to scale infrastructure, reduce build times, and unlock more abundant industrial capacity in the United States.   Resources: Follow Alex on X: https://x.com/alexmodon Follow Davide on X: https://x.com/davideasnaghi Follow Erin on X: https://x.com/espricewright Stay Updated: Find a16z on YouTube: YouTube Find a16z on X Find a16z on LinkedIn Listen to the a16z Show on Spotify Listen to the a16z Show on Apple Podcasts Follow our host: https://twitter.com/eriktorenberg   Please note that the content here is for informational purposes only; should NOT be taken as legal, business, tax, or investment advice or be used to evaluate any investment or security; and is not directed at any investors or potential investors in any a16z fund. a16z and its affiliates may maintain investments in the companies discussed.
