SPARETECH Raises $20M Series B to Attack $169M Inventory Problem

SPARETECH has raised $20 million in Series B funding, co-led by Blume Equity and Insight Partners with participation from Headline, to bring AI-driven spare-parts availability to North America. The company announced the round on November 10, 2026. The capital will fund AI development for industrial spare-parts availability, push surplus parts back into circulation and finance geographic expansion.

The average manufacturer sits on $169 million worth of spare-parts inventory, according to SPARETECH's 2026 benchmark report. That is the number the Stuttgart-born software company wants to shrink — aggressively.

Why do plants hoard spare parts?

The inventory problem begins with downtime risk. A single stockout can halt production and idle an entire line, which pushes plants to hold extensive stocks as insurance. Industrial automation compounds the burden: one new production line can introduce thousands of parts that someone has to stock.

SPARETECH's existing enterprise software attacks this on the data side. It uses verified original-manufacturer data to standardize spare-parts records, set inventory levels across plants and support sourcing and surplus resale across its network. The planned AI extends that model from visibility and recommendations to physical availability — a maintenance team should be able to rely on a required part even when it sits on another company's shelf.

The caveat is obvious: a part on someone else's shelf is only reliable if the network can deliver it fast. That is the engineering problem the $20 million must solve.

What did the founders promise?

Chief executive and co-founder Martin Weber set a hard target: "to cut spare parts inventory by 60% in the next three years, while securing the same uptime." That is a steep claim — and one that will be measurable by 2029.

Chief operating officer and co-founder Lukas Biedermann framed the value differently. The approach is intended to put idle parts back into circulation, he said, allowing cash tied up in stock to be used elsewhere in the business. In plain terms: a manufacturer's $169 million inventory problem becomes working capital again.

Is the growth real?

SPARETECH reported fivefold revenue growth since the start of 2024. Its catalog exceeds 40 million verified parts, and its network spans 15,000 manufacturer and supplier partners.

The customer list carries weight. Nestlé ran a global rollout that brought 320 plants in 70 countries online in less than a year. Porsche, VW, Bosch and Sanofi also use the software.

Takeaway: the traction figures come from the company itself, but the enterprise names are verifiable and the deployment scale at Nestlé is unusually fast for industrial software.

What does the survey actually say?

SPARETECH's 2026 benchmark report, based on a survey of 362 manufacturing executives, sketches the size of the problem:

• Average spare-parts inventory of $169 million per company
• More than 50% of organizations lack global visibility across operations
• 18% of maintenance, repair and operations inventory remains unused after five years
• 45% have no standardized global data-enrichment process

The survey covered the United States, Canada, Germany, Austria, Switzerland, the Nordics and the Benelux countries. An independent research firm conducted it in March and April 2026, which gives the findings a defined respondent base.

One caution: SPARETECH commissioned the survey that quantifies the market it sells into. The independent execution helps, but the framing serves the vendor.

Why North America, and why now?

Insight Partners managing director Brad Fiedler called North America the next stage of SPARETECH's growth, pointing to large American plant networks with substantial capital tied up in spare parts. For a company that has grown fivefold since early 2024, the U.S. industrial base is the largest untapped pool of that trapped capital.

The financing marks a shift from documenting idle stock to coordinating where parts are held and how they can be sourced. The central test is whether SPARETECH's network can make another company's surplus a reliable substitute for on-site inventory — without sacrificing the production uptime that made those large buffers attractive in the first place. Weber's 60% target now has a three-year clock running on it.
