Blume Equity and Insight Partners co-lead SPARETECH's Series B to help manufacturers cut spare parts inventory
SPARETECH's AI aims to cut manufacturers' spare parts inventory by 60% within three years, without risking downtime.
London, UK – 10th November 2026 – Blume Equity today announced that it has co-led a $20 million Series B in SPARETECH, the German-headquartered provider of enterprise AI for spare parts management. Insight Partners co-led the round, with participation from Headline. Insight and Headline are both existing investors in SPARETECH.
Spare parts management is one of manufacturing's most persistent inefficiencies. A single stockout can halt production and idle an entire line, so plants hold extensive inventories as a safeguard. SPARETECH's 2026 benchmark report puts the average value of spare parts inventory at $169 million per company, leaving significant capital sitting on the shelf.
SPARETECH is moving the market beyond insights and recommendations towards measurable outcomes: lower inventory with the same uptime. Its AI makes sure the right part is available when a plant needs it, even if that part sits on another company's shelf.
SPARETECH has grown revenue fivefold since the end of 2023. Over the same period, its catalogue has grown to more than 40 million verified parts, and its network to 15,000 manufacturer and supplier partners. A global rollout for Nestlé, a SPARETECH customer, put 320 plants across 70 countries live in less than a year.
Blume Equity has been tracking SPARETECH since 2024, as the company was a strong fit with its focus on smarter industry and more climate-resilient economies, and began discussions in 2026.
SPARETECH will use the funding to continue building the AI that secures spare parts availability for industrial companies, expand its presence in North America and new regions, and deepen its work with existing customers.
