Xometry (NASDAQ: XMTR): Building the AI-Native Operating System for Global Manufacturing

Xometry
01What the Company Does — In Plain English
Xometry is an online marketplace that helps companies get custom metal and plastic parts manufactured.
An engineer uploads a digital design for a part. Xometry’s software analyzes the design, provides an instant price and delivery estimate, and then assigns the order to a qualified manufacturer in its global supplier network.
In practical terms, Xometry is trying to replace a slow process of emailing drawings to factories, waiting for quotes, comparing suppliers, and manually coordinating production with an Amazon-like digital experience for custom manufacturing.
02Why Now
Xometry appears to be reaching the point where product improvements, buyer growth, supplier density, and operating leverage are reinforcing one another. Q1 2026 revenue increased 36%, marketplace revenue increased 40%, and marketplace gross profit increased 53%.
The Siemens partnership adds a potentially important new distribution channel. Instead of requiring every engineer to begin at Xometry.com, Xometry’s manufacturability, pricing, sourcing, and execution intelligence could appear inside industrial-design software at the moment a part is being created.
03Investment Thesis
- Xometry is digitizing a large offline market. Management has estimated an addressable opportunity above $260 billion across the manufacturing processes the marketplace currently serves, while penetration remains below 1% in important categories.
- The marketplace becomes more useful as both networks grow. More buyers generate demand and proprietary transaction data. More suppliers add capacity, manufacturing processes, certifications, and geographic flexibility.
- AI is the core operating engine. Xometry uses proprietary data to estimate manufacturability, price, lead time, and the supplier most likely to execute successfully.
- Enterprise adoption can increase revenue quality. Customers are moving from isolated prototype jobs toward repeat production orders, procurement collaboration, and broader supply-chain relationships.
- Siemens could expand distribution and strengthen the moat. Embedding Xometry intelligence inside design workflows could create qualified demand at lower acquisition cost and position the platform earlier in the product-development process.
- Operating leverage is becoming visible. Q1 adjusted EBITDA improved by $10.4 million year over year to $10.5 million, while marketplace gross profit grew faster than revenue.
- The principal risk is valuation and execution. Xometry must sustain unusually strong growth, protect supplier economics and fulfillment quality, and prove that new AI and partnership initiatives create durable high-margin revenue.
04CEO Playbook
The Mission
“Make the world’s manufacturing capacity accessible.”
— Xometry founder vision
The mission is to turn thousands of independent factories into an accessible digital network. Buyers obtain broader and faster access to manufacturing capacity, while suppliers receive new work without having to build a national sales organization.
The Prize
“A massive, complex and highly fragmented custom-manufacturing market.”
— Management’s recurring market-opportunity framework
Xometry is targeting more than $260 billion of spending across CNC machining, sheet metal, additive manufacturing, injection molding, die casting, and related processes. Management’s core argument is that most of this market remains offline and that Xometry can grow for years without approaching saturation.
The Edge
“Our networks continue to grow and create increasing network effects.”
— Randy Altschuler, Q4 2025 earnings call
Xometry’s edge is the combination of proprietary quoting data, approximately 5,000 active suppliers, more than 85,000 active buyers, and the real-world outcomes of completed jobs. Every transaction provides additional information about cost, lead time, quality, supplier performance, and buyer behavior.
The Proof
“We delivered 36% revenue growth year-over-year, underscoring the strength of our marketplace innovation and expanding global network.”
— Xometry management, Q1 2026 results
The proof is simultaneous acceleration in marketplace revenue, gross profit, active buyers, revenue per buyer, and adjusted EBITDA. Q1 marketplace gross profit grew 53%, materially faster than marketplace revenue growth of 40%.
The Next Move
“AI-powered intelligence will define the next generation of industrial software.”
— Xometry / Siemens strategic partnership announcement
The next move is to distribute Xometry’s intelligence beyond its own marketplace. Siemens Xcelerator can place instant manufacturability, pricing, sourcing, and execution intelligence inside the software engineers already use to design products.
05CEO Signals Timeline
The quarterly calls show a clear progression: Xometry first emphasized becoming the digital rails for a fragmented offline market, then demonstrated stronger network effects and enterprise adoption, and finally positioned its AI models as infrastructure that can extend beyond Xometry’s own marketplace.
“We are deploying generative AI at scale to improve experience and drive additional value for both our buyers and suppliers…to enhance our position as the digital rails in this massively fragmented and traditionally offline custom manufacturing market.”
— Randy Altschuler, Q2 2025 earnings call
Signal: Management’s focus was moving beyond marketplace growth alone. Xometry wanted its software, AI, TeamSpace, ERP integrations, and supplier tools to become embedded infrastructure inside customer procurement and supplier operations.
“Our AI-powered marketplace is increasingly becoming the essential digital infrastructure for a predominantly offline and fragmented industry. We are driving enterprise engagement, expanding our networks of buyers and suppliers, and increasing market share through technology.”
— Management message, Q3 2025 earnings materials
Signal: The infrastructure thesis began showing up in the numbers. Marketplace revenue increased 31%, active buyers increased 21%, marketplace gross profit increased 40%, and record marketplace gross margin demonstrated that network growth and AI pricing were improving the economics of the platform.
“It is a pivotal time in manufacturing driven by accelerating digital transformation, increasing customer demands for speed and transparency, rapid AI-driven innovation, and the crucial need for resilient supply chains…Xometry’s AI-native marketplace is digitizing how custom manufacturing is priced, sourced and fulfilled by replacing manual legacy processes.”
— Randy Altschuler, Q4 2025 earnings call
Signal: The founder broadened the story from online procurement to a structural transformation of manufacturing. He connected Xometry to AI adoption, reshoring, supply-chain resilience, and increasing demand for qualified domestic capacity.
“The Siemens partnership is a strong external proof point that our core AI models are becoming the infrastructure for how the industrial world designs and sources parts…Enterprise customers are not experimenting with us anymore, they are expanding.”
— Sanjeev Singh Sahni, Q1 2026 earnings call
Signal: The thesis moved into its most ambitious phase. Xometry’s intelligence is no longer confined to its own marketplace; Siemens can embed it inside design workflows, while enterprise customers increasingly use Xometry for recurring production and broader bills of materials.
