Company profile

researched Aug 2026

GoodBuy Gear operates an online managed marketplace through which parents, brands and retailers recirculate used and open-box baby and children's products, including strollers, bassinets, car seats, high chairs, carriers, rockers, changing pads and play mats. Items are listed with an assigned condition grade such as Open Box, Barely Used or Gently Used, shown alongside the original retail price and the discounted marketplace price, and are generally single-unit listings.

On the supply side, the company handles the operational work of resale for sellers: it offers at-home pickup or drop-off options and manages photographing, cleaning and listing items. Sellers can receive up to 85% of an item's sale value. On the demand side, buyers shop nationwide with shipping, with free shipping offered on orders above $100, and the company runs promotional offers tied to specific brands. Customer support is provided by chat and email during weekday business hours (9am-5pm EST).

The company has expanded its category coverage over time, including a 2023 move into selling pre-owned, quality-inspected car seats, and in August 2024 acquired JoyLet, a baby and kid gear rental membership service, discontinuing JoyLet's rental offering and moving those items to the GoodBuy Gear marketplace for purchase.

Founding story

The company was founded in 2016 by Kristin Langenfeld and Jessica Crothers as a marketplace for parents to buy and sell gently used baby and children's products; it is described as female-founded and mom-founded, with Langenfeld serving as CEO.

Business model

Managed marketplace: GoodBuy Gear takes in used and open-box baby and kid gear from parents, brands and retailers, inspects and grades it, and handles photography, cleaning and listing, with sellers receiving up to 85% of the sale value of each item sold. The company also works with brand and retail partners on recirculating inventory. Sources describe the business as a marketplace model.

Revenue is derived from sales of secondhand and open-box items on its marketplace, with sellers keeping up to 85% of an item's sale value and the remainder retained by the company.

Traction

As of June 2023 the company reported over 270,000 secondhand items sold and more than 12,000 families having resold items through the platform, with average year-over-year growth of 186% since 2018. In the first months of 2023 it doubled its base of brand and retail partners.

Latest developments

The August 2024 acquisition of JoyLet added the company's personalized gear roadmap concept to the GoodBuy Gear customer experience and moved former rental inventory onto the marketplace for sale. The site continues to list open-box and used gear from brands including Cybex, Halo, Joolz, Mockingbird, Silver Cross, Thule and Maxi-Cosi.

Market position

Described in its funding announcement as the leading online resale marketplace for baby and kid gear, addressing a US market in which parents are said to spend $87 billion annually on baby and kid gear. The company reported that 83% of marketplace inventory is never or barely used before listing, and named as winner of the Denver Business Journal's 2023 Small Business Awards.

Full-service handling of the resale process for sellers (pickup or drop-off, cleaning, photography and listing), condition-graded and quality-inspected inventory, and the sale of pre-owned quality-inspected car seats, described in 2023 as a first in the industry. Buyers are stated to save an average of 50% off retail.

Technology

An online marketplace platform that lists individual secondhand and open-box items with condition grading and item-level attribute details (for example whether accessories such as mattress pads, rain covers or cup holders are included), supported by internal quality inspection processes, including inspection of pre-owned car seats.

Go-to-market

Direct-to-consumer e-commerce on goodbuygear.com with nationwide shopping and shipping, supported by free shipping on orders over $100 and bundled promotional discounts. Supply is acquired through white-glove selling services with at-home pickup and drop-off locations in selected metros, and through partnerships with brands and retailers.

Parents and families buying and reselling baby and children's gear, plus brands and retailers seeking a channel to recirculate used, returned or open-box inventory.

Geography

Headquartered in Denver, Colorado, with a fulfillment center in Malvern, Pennsylvania. As of June 2023 white glove selling services were offered in Denver, Philadelphia, Washington D.C. and New York City and their surrounding metro areas, with shopping and shipping available nationwide in the United States.

History

Founded in 2016, GoodBuy Gear raised a $750,000 seed round about a year after founding. In June 2023 it announced a total of $14 million in funding co-led by Interlock Partners and existing investor Revolution Ventures, at which point Interlock's Carl Sparks joined the board. Also in early 2023 it began selling pre-owned, quality-inspected car seats and doubled its brand and retail partner base. In August 2024 it acquired JoyLet, a gear rental membership business founded by Alli Cavasino and Natalie Poston, discontinuing JoyLet's rentals and transferring items to the GoodBuy Gear marketplace.
