Company profile
researched Aug 2026Mobius Materials operates an online marketplace for electronic components, focused on redirecting manufacturers' excess and surplus inventory back into the supply chain. Buyers can source parts through requests for quote (RFQ) or by creating an account, while holders of surplus stock list parts for sale. The company states it sells verified integrated circuits from established semiconductor manufacturers, including Texas Instruments, Analog Devices, Vishay, Murata, Onsemi, Microchip, ST Microelectronics and NXP Semiconductors, and publishes in-stock unit counts by manufacturer ranging from roughly 136,000 NXP parts to 8.5 million Murata parts.
The company positions its offering around two buyer benefits: price, with a stated 10-70% discount versus market rates on common parts depending on component grade, and availability, providing access to scarce stock held by other hardware manufacturers during shortages. It says it accepts parts only from vetted suppliers and tests parts for authenticity, and markets a sourcing timeline of under two weeks for certified parts, supported by live product walkthroughs booked with its team.
Founding story
Founder and CEO Margaret Upshur describes the company's origin in her prior role as head of operations for an IoT module manufacturer, where each year she discarded hundreds of thousands of dollars of new excess components while simultaneously paying high prices for comparable parts. Mobius Materials was framed as a way to fix that mismatch by improving manufacturers' P&L and returning surplus parts to the supply chain.
Business model
Two-sided marketplace intermediating between manufacturers holding excess electronic components and buyers seeking those parts, with the company handling supplier vetting and authenticity testing of the goods transacted.
Traction
The company publishes in-stock inventory counts across eight semiconductor manufacturers, including 8.5M+ Murata, 1.6M+ Vishay, 1.4M+ Onsemi, 578k+ Texas Instruments, 518k+ ST Microelectronics, 296k+ Microchip, 212k+ Analog Devices and 136k+ NXP parts. Cited customer testimonials report substituting 12 parts on a bill of materials for more than 25% cost savings, and a seller moving from fewer than two parts sold per month through brokers to more than 10 orders per month after working with Mobius.
