Weft

Weft was a Burlington, Vermont based supply-chain logistics startup, founded by Marc Held around 2013-2014, that combined hardware sensors and software to track the shipping of physical goods worldwide in real time. It raised a seed round of under $1M led by Andreessen Horowitz (a16z) and Data Elite, with plans for a $5M Series A. The company was surfaced as an a16z portfolio company and added to the API Evangelist network as a stub for enrichment. As of this enrichment pass the company appears defunct: no live corporate website, no developer portal, and no public API surface could be found. Candidate domains were probed and none host an active product (weft.com refused connection, weft.io does not resolve, weft.ai is a parked domain listed for sale).

Weft is profiled on the APIs.io network. Tagged areas include Company, Logistics, Supply Chain, Shipping, and Freight Tracking.
