Company profile

researched Aug 2026

Hemster operates a technology-enabled tailoring service that connects apparel retailers and shoppers to a managed network of local tailors. Shoppers are measured either in a partner store's dressing room or at home using the company's patent-pending "RulerSticker" markers, which allow store associates or consumers without tailoring experience to take alteration measurements quickly. Garments are then routed to a tailor selected on the basis of machinery, skill set and available capacity, with the company citing a 48-hour turnaround at the time of its post-seed round and a 1-3 day turnaround with a 99.4 percent accuracy claim on its current site.

The consumer-facing product saves a shopper's measurements as reusable "Patterns" generated by a Fit Profile algorithm, which can subsequently be matched to new or existing garments so that alterations can be repeated without re-fitting. Hemster markets free tailoring when consumers shop from its brand partners, provides pre-paid shipping for garments sent in, and manages orders through a customer portal. The company also offers (re)vive, a service positioned to help brands convert returned and deadstock inventory into revenue.

Hemster positions itself against the fashion industry's standard small/medium/large sizing, which its founder states does not fit roughly 90 percent of shoppers, and frames its service as reducing fit-related returns for retailers while modernizing tailoring through technology.

Founding story

Founder and CEO Allison Lee grew up in South Korea, where shoppers typically select size by weight and tailoring is expected even on budget garments. She contrasted this with the US small/medium/large system, which she said does not fit almost 90 percent of people, and founded Hemster to make solving fit simple, convenient and cost-effective for consumers while giving brands a scalable service offering.

Business model

Hemster sells tailoring and alteration services to both retailers and end shoppers, operating an outsourced network of local tailors rather than employing tailors directly. Services are delivered in partner stores, at residential properties and through mail-in/home pickup, and the company also offers a (re)vive product aimed at monetizing brand returns and deadstock.

The company has described its model as an arbitrage between what it charges customers (retailers and shoppers) and what it pays tailors, with revenue from tailoring services at retail locations and residential properties. It cited an average order value above $60 with tailoring and transportation costs at less than half of that, plus an additional $15-25 fitting fee for in-home services, and low marketing and user-acquisition costs due to retailer, residential property and mall partnerships.

Traction

At the time of its Regulation CF offering, Hemster reported over 230 percent quarter-over-quarter growth since launching in 2017, average order value more than doubling within six months, a 99 percent accuracy rate, expansion from one pilot mall partnership to three live locations in ten months, an average 15 percent increase in monthly retailer sales, and a launch waitlist of 400 grade-A shopping centers via Westfield, Simon, Macerich and GGP. Named customers and partners have included Zara, Michael Kors, Club Monaco, Outdoor Voices, Reformation and Bonobos, plus residential groups Greystar, Crescent Heights and Maximus. The company later added brand partnerships with Diane von Furstenberg, Outdoor Voices and Alo Yoga. Consumer reviews aggregated on Yelp give Hemster a 3.9 average across 100 reviews and four US locations, with multiple recent reviews citing delays, non-returned garments and poor communication.

Latest developments

Hemster currently markets (re)vive, a service for turning returns and deadstock into revenue, alongside its Pattern-based fit product that promises 1-3 day tailoring turnaround with 99.4 percent accuracy and free adjustments.

Full profile — market position, technology, go-to-market, geography, history, risks & controversies

Market position

Hemster describes a market in which fashion retailers spend more than $35 billion annually creating and managing multiple sizes and premium retailers such as Nordstrom, Bloomingdale's, Men's Wearhouse and the Armani group spend over $500 million a year on complimentary alteration services. It positions itself as providing nationally consistent, streamlined in-store tailoring for brands that struggle to deliver consistent service through independent local tailors.

The company states its tailors are trained and experienced in specific garments and alteration skills, making its network four to five times more productive than the average tailor, and that its patent-pending RulerSticker allows accurate fitting in under a minute by untrained store associates. Reusable fit Patterns and retained perfect-fit data further distinguish the offering from one-off local tailoring.

Technology

Core technology includes the patent-pending RulerSticker markers used to capture accurate measurements without tailoring expertise, a Fit Profile algorithm that stores a shopper's measurements as reusable garment-specific "Patterns," a matching capability that applies saved Patterns to new or existing garments, and an order-routing system that assigns each garment to the best-suited local tailor based on machinery, skills and capacity. The company retains customer fit data, which its lead investor described as a key asset for retailers and marketplaces.

Go-to-market

Hemster acquires demand through partnerships rather than direct marketing: deals with retail property groups and mall operators place its service inside stores, brand partnerships offer free tailoring to those brands' customers, and residential property partnerships extend in-home fittings to luxury apartment residents. It also runs a direct consumer flow on its website with self-measurement ruler stickers and pre-paid shipping.

Apparel retailers and brands (premium and mass-market), retail and residential property groups operating malls and luxury apartment buildings, and individual shoppers who need garments altered to fit.

Geography

Hemster operates in the United States, with Yelp listing four locations including San Francisco, New York and Santa Clara, California; it said it would use its post-seed funding to scale into new US markets.

History

Hemster launched its service in 2017 and was part of the XRC Labs W18 Cohort 5 batch, presenting at an XRC demo day in New York. It ran a Regulation CF equity crowdfunding offering on Republic that closed on November 27, 2018 with 527 investors. Roughly 18 months after the XRC demo day, in July 2019, it announced a $4 million post-seed round led by Bullpen Capital alongside brand partnerships with Diane von Furstenberg, Outdoor Voices and Alo Yoga, bringing total funding collected to $5 million. Industry advisors have included XRC Labs founder Pano Anthos and former Neiman Marcus CEO Karen Katz. The company has since shifted its consumer positioning toward reusable fit Patterns and launched (re)vive for returns and deadstock.

Risks & controversies

Yelp reviews from the past several years describe repeated operational failures, including multi-week delays beyond promised 10-business-day or 2-3 week turnarounds, orders placed on hold without proactive notification, unanswered customer service emails, and at least one garment reported lost in shipping; the aggregate rating is 3.9 from 100 reviews. Some reviewers reached Hemster through retail partner Reformation. One reviewer disputed the company's technology claims.
