Physics AI is Rewriting the Rules of Engineering

Introduction: The Velocity of Invention

In 1903, the Wright brothers moved the world forward through a grueling "build-test-fail" cycle. Each iteration of their prototype flying machine took roughly a year to design, construct, and learn from. For over a century, this has been the fundamental, frustrating rhythm of engineering: progress is strictly gated by the speed at which physical ideas can be validated in the real world.

While digital simulations eventually compressed these year-long cycles into weeks, I have hit a new ceiling. In an era of rapid climate change and geopolitical tension, the demand for innovation in semiconductors and renewable energy is outstripping the pace of traditional simulation. PhysicsX is effectively hot-wiring the engine of discovery. Founded by former Formula 1 engineers and AI researchers, the company is acting as the catalyst for a new era of "imagineering," utilizing physics AI to collapse timescales and redefine what is possible in the physical world.

--------------------------------------------------------------------------------

1. Collapsing the Time-to-Market Dimension

The leap from digital simulation to an AI-native platform represents a fundamental collapse of the time-to-market dimension.

Where traditional simulations once ground through weeks of compute time, PhysicsX integrates physics AI directly into the engineering workflow to deliver results in seconds.

“We're integrating physics AI directly into engineering workflows, turning processes that used to take days into something that can happen almost instantly,” explains Garazi Gómez de Segura, Senior Principal Data Scientist at PhysicsX.

This speed is more than an efficiency gain; it is a tactical weapon in the race for technological sovereignty.

In the semiconductor industry—a strategically vital sector where a week's delay costs millions—this technology is already slashing the time required for equipment prototyping.

The same "instant" iteration was applied to Microsoft Surface devices, where engineers used the platform to optimize cooling fan designs and thermal behavior at a pace impossible with legacy tools.

When hardware can iterate at the speed of software, the competitive advantage shifts to those who can move the fastest.

2. Doubling the Yield of Our Most Critical Resources

Physics AI is moving beyond the lab to tackle the foundational constraints of the global energy transition, specifically within the mining and metals sector. Copper is the literal nervous system of our modern world—the essential conduit for electrification, renewable energy grids, and the massive datacenters required to power the AI revolution itself.

Currently, traditional extraction methods are painfully inefficient, recovering only about 40% of usable material from mined ore. PhysicsX is working with global leaders to leapfrog decades of incremental improvements, aiming to increase recovery rates significantly—potentially up to 80%.

“Every electric motor, generator, and data centre relies on copper,” explains Mark Huntington, Managing Director North America at PhysicsX. “If supply becomes constrained, the knock-on effects ripple through the entire energy system.”

By potentially doubling the yield of this critical resource, physics AI becomes a macro-economic lever, ensuring that the raw materials for global electrification remain accessible and sustainable.

3. The End of the Engineering Silo

Traditional engineering is a fragmented war of compromises. Specialists in aerodynamics, structural integrity, and thermal behavior typically work in silos, where one department’s optimization is often another’s failure.

The System-Level Perspective Physics AI models are inherently multidisciplinary, functioning as a "universal language" for physical forces. As Garazi Gómez de Segura puts it: “AI doesn’t care about those traditional engineering boundaries.”

Because these models learn multiple types of physics simultaneously, they allow engineers to treat a complex machine not as a collection of parts, but as a single, coherent system. This holistic approach ensures that trade-offs are identified and resolved in the design phase, allowing for far more ambitious, integrated architectures that would have been deemed "too risky" under traditional siloed workflows.

4. From Reactive Correction to Predictive Control

In high-stakes industrial environments, the status quo is reactive: observe a decline in performance, investigate the cause, and fine-tune parameters after the event. This "recover after failure" mentality is a massive bottleneck to industrial efficiency.

PhysicsX is granting engineers a form of "God-mode" over their operations through predictive reasoning. By embedding physics-grounded models—rather than models built on scientific guesswork or static rules—directly into workflows, engineers can evaluate thousands of potential parameter changes in parallel.

This allows operators to see the complex, delayed ripple effects of a change across a physical system before they ever hit "go." It transforms the role of the engineer from a firefighter reacting to a crisis into a strategist selecting the optimal future from a field of certain outcomes.

5. Scaling 'Imagineering' with Large Physics Models

The emergence of "Large Physics Models" (LPMs) and "Large Geometry Models" (LGMs) marks a turning point where the bottleneck of innovation shifts from technical execution to human creativity. Unlike traditional solvers that crunch numbers, these models reason through shape and force simultaneously, understanding the fundamental relationship between geometry and performance.

This is best illustrated by the high-efficiency cooling plates developed through the platform. These designs feature organic, complex geometries that defy traditional engineering intuition and would likely never have been conceived by a human designer alone. When an AI can generate and refine these designs in a fraction of a second, the physical constraints of testing vanish.

“When evaluation time drops to seconds, the main question becomes what should I optimise for?” says Benjamin Levy, Principal Data Scientist at PhysicsX.

Conclusion: The Century of Progress in a Decade

The mission of PhysicsX is a manifesto for the next industrial revolution: to bring the next 100 years of engineering progress into the next 10. By building a new engineering software stack on the high-performance computing power of Microsoft Azure, they are ensuring that the benefits of physics AI are compounding across every sector it touches.

Whether it is perfecting a turbine's efficiency, doubling a mine’s output, or keeping a datacenter cool, these advancements provide the foundation for a more resilient physical world. I'm moving into an era where the physical world is becoming as malleable and iterative as code, and the only remaining limit is our own ambition.

What would you build if the cost, time, and risk of testing were no longer a barrier to your imagination?

Building the Next AI Giant

1. Introduction: The Laboratory-to-Market "Phase Transition"

For a researcher, the realization that a laboratory discovery has commercial potential is intoxicating. However, transitioning from academia to a startup is a radical "phase transition" in physics terms. You are moving from the comfort of peer review and multi-year grant cycles to the brutal scarcity of the "startup clock." In the lab, you are rewarded for new discoveries; in the market, the only reward is tangible progress toward a commercially valuable product.

The era of "AI Hype" is over; the era of "Hands-on Builders" has begun. According to the 2025 ICONIQ Builder’s Playbook, 47% of AI-native companies have already reached critical scale and proven market fit, compared to a staggering 13% of AI-enabled incumbents. This massive performance gap is driven by execution, not just elegance. While you may be refining a model, 80% of AI-native builders are already investing in agentic workflows—autonomous systems that solve multi-step problems for users. This post distills the hard truths from the 2025 ICONIQ and Y Combinator playbooks to help you navigate this transition.

2. The "Boom" Paradox: Why Harder Companies are Easier to Build

Technical founders often retreat to "simple" ideas—like a mobile shopping app—thinking they are lower risk. This is a fatal strategic error. As Sam Altman and Boom Supersonic’s Blake Scholl have proven, it is often easier to start a "moonshot" than a "simple" app.

Why? Because an ambitious, technically monumental idea acts as a talent magnet. In an era where AI/ML engineers take an average of 70+ days to hire, the primary bottleneck isn't capital; it's people. A supersonic jet or a breakthrough neural architecture attracts the world's best minds and most aggressive investors. A "simple" app attracts no one.

"In many ways, it’s easier to start a hard company than an easy company." — Sam Altman

For scientists, technical complexity is your greatest recruiting tool. If the problem isn't hard enough to scare off 99% of builders, you won't attract the top 1% of talent required to survive.

3. Your PhD is Not a Moat (and Neither is Your Algorithm)

In the Valley, an elegant algorithm that solves a non-existent problem isn't a breakthrough; it’s a post-mortem. A PhD or a high-impact publication is a badge of rigor, not a defensible moat. There are thousands of AI PhDs globally; model sophistication is becoming a commodity.

A real moat, as defined by the latest venture playbooks, requires a 10x breakthrough, not a 10% incremental improvement. If your algorithmic advantage is only 10% better than the state-of-the-art, you will be crushed by an incumbent with better distribution. A genuine moat consists of:

  • Proprietary Data Access: Exclusive datasets that cannot be scraped, bought, or synthesized.
  • Deep Domain Specificity: Solving a high-friction problem in an underserved vertical (e.g., healthcare or logistics) where general models fail.
  • Execution Velocity: The ability to iterate and ship 10x faster than a competitor can copy.

4. Carving Up an "Empty Suitcase": The 80/20 Equity Rule

The conversation between a Principal Investigator (PI) and a student regarding equity is the most fraught part of a spin-out. But the "hard truth" is simple: equity is a tool for future motivation, not a reward for past work. You are currently on mile two of a 26-mile marathon; the academic research only got you through the first mile.

The "20-80 Rule" dictates that 20% of equity is for the "creators" (past work), while 80% is for those doing the "sweat and sacrifice" (the next 7–10 years of full-time work).

"At the beginning, you’re carving up an empty suitcase." — Serial Entrepreneur

Hard Truth: Investors view non-active academic co-founders as "dead weight" on the cap table. To remain fundable, academic co-founders staying in the lab should own no more than 10%. Anything higher is a massive red flag that will kill your Series A before it starts.

5. PMF is a Spectrum, Not a Summit

Product-Market Fit (PMF) is not a "Eureka" moment; it is a "garden to be tended daily." In AI, traditional signals can be false positives. You must view PMF as a spectrum of signals:

  • Light Signal: Early users love the "wow" factor, but retention is inconsistent.
  • Moderate Signal: Pockets of traction and revenue appearing in a well-defined niche.
  • Strong Signal: High retention where customers "pull" the product faster than you can build.

The critical AI-native metric is the "Second-Bite Usage Rate." For example, Perplexity CEO Aravind Srinivas tracks cohort analysis to move from 80% to 100% query retention—ensuring usage becomes a habit, not a novelty.

Lesson: Embed, don't disrupt. Bessemer’s case study on Brisk Teaching shows that PMF was found not by building a new platform, but by creating a Chrome extension that embedded AI into existing workflows. Teachers saved 10+ hours a week without leaving Google Docs or YouTube. If you require a customer to change their entire workflow to use your AI, you will fail.

6. The Geographic Fallacy: Why Silicon Valley is Now a "Distributed Phase"

The assumption that you must move to San Francisco is outdated. We have undergone a "phase transition" to a distributed model. Using the Network Access Metric (N = C \times Q \times T), you can achieve 80% of the networking benefit of SF through strategic travel while maintaining significantly more runway.

Small, remote teams using AI as a 5-10x skill multiplier are currently outbuilding larger, centralized incumbents because they can focus on product over social posturing.

7. The "100-Interview" Mandate: Stop Coding, Start Talking

Scientists often fail by "building in isolation" for 12 months. The business world requires the Scientific Method: Hypothesis → Experiment (Customer Discovery) → Data.

Before you write a line of code, you must conduct 50–100 customer interviews. Use a "Wizard of Oz" MVP—manually performing the task the AI would do to validate demand. This transition requires a 250-hour skill stack that most PhDs lack:

  • 100 Hours: Sales and Business Fundamentals (Lead gen, unit economics).
  • 50 Hours: Product Management (User research, design thinking).
  • 50 Hours: Marketing (Content strategy, viral loops).
  • 50 Hours: Design and Operations.

Takeaway: There is no revenue without 100 customer conversations. Period.

8. Conclusion: From Theory to Execution

We are in the era of the "Builder’s Playbook." Strategic agility and execution velocity define the winners of the next decade, not just the number of citations on your last paper. The path from the lab to the market is grueling, but the upside is unparalleled for those who can trade scientific perfection for market grit.

In a world where AI models are maturing, is your edge in the elegance of your code, or the depth of the problem you’re actually solving?

Innovation is 1% inspiration; the other 99% is the grit to find Product-Market Fit.
