In this episode of Value Drivers, Peter Ho interviews Eduardo Torrealba, the co-founder and CEO of Lumafield, a company dedicated to helping manufacturers eliminate hidden defects by “seeing inside” their products. Torrealba, a mechanical engineer by training, was inspired by the semiconductor fabrication facilities near his childhood home and later dropped out of a PhD program to pursue entrepreneurship. His mission with Lumafield is to solve critical global crises in “atom space”—the physical world—where software alone is insufficient. By utilizing industrial CT scanning, Lumafield aims to “close the loop” between design and manufacturing, allowing engineers to push the limits of physics with the same precision and confidence found in semiconductor manufacturing.
Lumafield operates as a vertically integrated platform, designing its own hardware, writing its own software, and managing its own manufacturing. This technology has been adopted across diverse high-stakes industries, including medical devices for drug delivery, energy storage for batteries, and aerospace for mission-critical fighter aircraft parts. The company provides significant financial value to its customers through direct labor replacement, reduction in manufacturing scrap, and a vastly accelerated speed to market. Torrealba notes that their technology can resolve manufacturing issues in hours that previously took days, sometimes unlocking contracts worth hundreds of millions of dollars for their clients.
Operationally, Lumafield maintains a team of 150 people across offices in Cambridge and San Francisco. To manage the complexity of a hardware-and-software business, Torrealba tracks approximately 80 KPIs, blending traditional enterprise SaaS metrics like Annual Recurring Revenue (ARR) and Net Dollar Retention with manufacturing-specific data like inventory on hand and first-pass yield. He rejects the common sentiment that “hardware is hard,” viewing it instead as an excuse that hinders the creation of generational companies. Building something truly great requires solving difficult problems and maintaining operational excellence across every department simultaneously.
Takeaways for Entrepreneurs
For founders looking to scale, Torrealba offers several insights:
- Validate Market Assumptions Early: Lumafield initially believed that “digital manufacturing” like 3D printing would be their primary tailwind, but they quickly realized the real opportunity lay in traditional manufacturing like castings and injection molding.
- Location Matters for Venture Scale: While lifestyle businesses can be built anywhere, Torrealba argues that founders aiming for venture-backed tech success should move to hubs like San Francisco as quickly as possible to be near the necessary resources and talent.
- Prioritize Specific Learning: Rather than consuming general business media, Torrealba suggests “just-in-time” learning through direct, specific conversations with other CEOs and board members who have faced similar challenges.
- Identify Measurable ROI: To shorten sales cycles, focus on building a clear return on investment case for customers, such as automating manual quality checks or reducing line downtime.
- Maintain Perspective: Torrealba views being born in the United States as his “luckiest break,” providing an unparalleled foundation for building a company that hard work alone cannot replace in other parts of the world.

Why this conversation matters
Speed to market has become a decisive advantage, not a secondary benefit.
As Eduardo explains in the podcast, what ultimately matters is not just building better products, but shortening the time between discovering a problem and confidently moving forward. Across manufacturing-heavy industries, that speed increasingly determines who wins contracts, who scales, and who earns investor confidence. In electric vehicles and energy storage, Tesla built its early lead not only through technology or branding, but through faster manufacturing feedback loops. The ability to diagnose production issues quickly, adjust designs, and ramp faster than incumbents translated directly into deliveries, customer commitments, and market leadership. That same dynamic now cuts both ways, with Chinese EV players like BYD iterating even faster and pushing pressure back up the value chain. Speed is an advantage until someone else learns to move faster.
In aerospace, Eduardo’s examples underscore how speed to qualification is existential. In these high-consequence sectors, the ultimate metric isn’t just speed—it is Time to Certainty. By compressing the window between identifying a defect and verifying the fix, companies avoid the ‘waiting games’ that trap millions in working capital and stall multi-year programs. Companies such as Boeing and RTX operate in environments where a single unresolved manufacturing defect can delay certification by months. Those delays are not just operational. They are financial. Every month of delay pushes revenue further out, extends working capital requirements, and erodes project-level returns through the time value of money. As Eduardo notes, suppliers that can quickly identify internal defects, prove compliance, and keep programs on schedule become preferred partners on multi-year, multi-billion-dollar programs. Resolving an issue in hours instead of weeks materially changes cash flow timing, not just technical outcomes.
Quality, in this context, stops being an operational afterthought and becomes a financial lever.
Throughout the conversation, Eduardo repeatedly reframes quality in economic terms. Quality is often buried in the P&L as part of cost of goods sold. By eliminating destructive testing and manual bottlenecks, companies are not just fixing parts, they are plugging margin leakage and accelerating the cash conversion cycle. In that framing, quality improvements show up as margin preservation and faster cash recovery, not just better defect statistics. Scrap, downtime, destructive testing, and manual inspection all translate into delayed revenue, tied-up capital, and risk. Closing the loop between design and manufacturing shifts quality from a post-mortem exercise to an input into capital allocation. Faster insight means fewer buffers, less rework, and more disciplined use of cash. For CFOs and operators alike, this reframing matters because quality decisions increasingly show up in margin stability and cash flow, not just defect metrics.
Finally, this conversation cuts through macro narratives and focuses on execution.
As discussed on the podcast, reshoring, tariffs, and industrial policy matter, but they operate on multi-year timelines. Most operators and CFOs are making decisions on weekly and monthly horizons, dealing with volatile demand, supplier substitutions, and compressed customer timelines. Tools that shorten diagnosis and iteration cycles create immediate, measurable ROI regardless of where production ultimately sits.
Taken together, this episode highlights a broader shift. Competitive advantage in manufacturing is increasingly about decision velocity, economic clarity, and the ability to move fast without taking on disproportionate risk.
