Hemster

Hemster is a fashion-technology company that modernizes tailoring and garment fit through a digital "Fit Profile" system. Customers create a personalized fit pattern once, then match any garment — new or from their existing closet — to that saved profile so it can be tailored to their perfect fit rather than to a standard size. The platform aims to reduce returns, extend the life of clothing people already own, and remove size-related hesitation at purchase, with a sustainability angle around keeping garments out of landfill. Hemster operates a consumer web app at my.hemster.co and a related returns/deadstock product ((re)vive / byrevive.com). It is backed by Bullpen Capital. As of this profile Hemster publishes no public developer, API, or integration surface; this record is maintained in the API Evangelist network as a company lead.

Hemster is profiled on the APIs.io network. Tagged areas include Company, Fashion Technology, Retail, E-Commerce, and Tailoring.

Hemster’s developer surface includes signup flow, support, and 4 more developer resources.
