GoodBuy Gear Secures $14 Million in Funding

GoodBuy Gear, the leading online resale marketplace for baby and kid gear, announced a total of $14M in funding co-led by Interlock Partners and existing investor Revolution Ventures. The female-founded-and-led startup also received new funding from Crawley VenturesMana VenturesAccess VenturesRelay Ventures and Denver Angels.

The capital will enable GoodBuy Gear to further scale its online marketplace and solidify its position as the leading and most trustworthy baby and kid resale brand.

“Parents in the United States spend $87B on baby and kid gear every year, and most of those products are hardly used. In fact 83% of the inventory on our marketplace is never or barely used before it’s listed for resale—that’s the massive opportunity GoodBuy Gear was founded to solve,”

said CEO and co-founder, Kristin Langenfeld.

“With this funding, we are able to accelerate our pace in addressing the entirety of this substantial market.”

GoodBuy Gear enables parents, brands and retailers to safely and sustainably recirculate quality-used baby & kid products. The industry leader continues to grow its addressable market and deepen its penetration through expansions in product verticals, geographies, and partnerships. In the first months of 2023, GoodBuy Gear expanded to sell pre-owned, quality-inspected car seats—a first in the industry—and doubled the company’s base of brand and retail partners.

“Interlock is impressed with the rapid growth in demand for resale solutions in this space—from parents, brands, and retailers—and the monumental traction GoodBuy Gear has consistently achieved within all three verticals,”

said Carl Sparks, Managing Partner at Interlock.

“We are confident in GoodBuy Gear’s promise and capacity to lead here.”

Carl previously served as CEO of Academic Partnerships, CEO of Travelocity Global, President of Gilt Groupe and CMO of Expedia and has joined GoodBuy Gear’s board of directors.

GoodBuy Gear’s Series A investors were also inspired by the brand’s traction and growth, accompanied by strong fundamentals, and chose to up the ante this year, including Revolution Ventures who is now co-leading the series alongside Interlock VC.

“Trusted by retailers, brands, and parents alike, Goodbuy Gear has quickly become the go-to marketplace for sustainable and price-accessible baby and kids’ gear. We remain proud partners of Kristin and the team as they continue to scale this must-have solution for parents that solves the re-commerce imperative for retailers and brands,”

said Clara Sieg, Partner at Revolution Ventures.
