Founded 2018
SPARETECH, the German enterprise AI company for spare parts management, raised a $20M Series B (about 18 million euros) co-led by Blume Equity and Insight Partners, with Headline also participating, to keep building its AI, resell surplus parts and expand in North America.
Two growth investors share the lead on a $20M Series B
SPARETECH GmbH announced the round on 10 November 2026 in a press release datelined Munich. The amount is $20M as announced, about 18 million euros. Blume Equity, a European growth equity investor based in London and Amsterdam, and Insight Partners, based in New York, co-led. Headline, the San Francisco venture firm, also took part.

Insight is a returning name. It led SPARETECH’s EUR 10M Series A on 27 June 2023, alongside Headline, existing investors Plug and Play Tech Center and a group of angels (Insight Partners announcement). Headline therefore sits in both rounds.
The company describes the use of funds in three parts: keep building AI that secures spare part availability and resells surplus parts, expand in North America and new regions, and deepen work with existing customers. “The next stage of SPARETECH’s growth runs through North America,” said Brad Fiedler, Managing Director at Insight Partners. Michelle Capiod, co-founding partner at Blume Equity, said, “SPARETECH is exactly the kind of business we back.”
Original manufacturer data behind a Nestlé rollout in 320 plants
SPARETECH was founded in 2018 by Martin Weber (CEO) and Dr. Lukas Biedermann (COO). Its software helps manufacturers manage spare parts on verified original manufacturer data. The product line covers Global Spare Parts Search, Automated BOM Check, Data Lifecycle Management, Inventory Optimizer and Surplus Seller, the last one a way to sell parts a plant no longer needs.
The company names Nestlé, Porsche, VW, Bosch and Sanofi as customers. The Nestlé deployment is the number that stands out. According to SPARETECH, 320 plants in 70 countries went live in under a year.
Other metrics are company-reported as well. Revenue is up fivefold since the start of 2024, though the release gives no revenue figures to anchor that multiple. The catalog holds over 40 million verified parts and the company counts 15,000 manufacturer and supplier partners. The release does not disclose team size or valuation.
“Every customer we work with wants the same thing: the production line running with less inventory on the shelf,” Weber said. Biedermann put the economics plainly. “Every part sitting idle is cash that could be working somewhere else.”
A $1.02 billion software segment and a $169 million inventory problem
Start with the software market. MarketsandMarkets sized spare parts management at USD 1,021.3 million in 2025 and USD 1,820.2 million by 2030, a 12.3% CAGR (press release, 28 Nov 2025). That adds roughly 800 million dollars of annual software spend in five years. That figure sizes the software segment only. The scale of the problem sits in the next number.
SPARETECH’s 2026 benchmark report puts average spare parts inventory at $169 million per company. The company’s stated goal is to cut manufacturers’ spare parts inventory by 60% within three years at the same uptime. On that average, hitting the goal would free about 101 million dollars of working capital per manufacturer (our arithmetic, from the company’s two figures).
A company-reported fivefold revenue rise sits far above a 12.3% segment growth rate. The two figures measure different things, one company’s revenue against a segment’s spend, and the release gives no revenue base.
For scale within logistics and supply chain, sennder announced EUR 73M in equity on 11 November, a day after SPARETECH. SPARETECH’s round of about 18 million euros is roughly a quarter of that amount (our arithmetic).
A London-Amsterdam growth fund and a New York one aim at North America
Europe has a habit of building the industrial customer and then watching a US fund write the growth check. Here a European growth equity firm and a New York firm share the lead, and Fiedler’s quote puts the next stage in North America.
A part sitting idle on a shelf never complains, which may be why it has sat there for decades. The buyers named are large, the data problem is concrete and the payoff, in Weber’s and Biedermann’s words, is less inventory and cash put back to work.
What to watch is simple. First, whether the Nestlé pattern repeats, a global rollout in under a year, with the next North American name. Second, whether Surplus Seller turns idle inventory into resold parts at scale. Third, whether the revenue multiple holds once the base grows. For a wider view of how rounds like this compare, the fundraising data hub tracks the amounts and investors, and the SPARETECH record holds the company facts.
The shelf is the next place worth building on
Industrial AI earns its keep on the plant floor, where a line keeps running because one part was in the right place. SPARETECH has 320 Nestlé plants live, a stated target of 60% less inventory at the same uptime, and now $20M and two co-leads to chase it across the Atlantic.
We will be watching the numbers. Plenty of European industrial problems look this unglamorous, and the ones with clean data behind them tend to be the ones worth building on.
