ByeAgain

Overview
ByeAgain is an Austrian refurbishment-as-a-service company that turns returned, used and surplus consumer goods into resale-ready inventory for brands and retailers. Founded in 2022 by Wolfgang Weingraber and Jan Kranner and based in the Graz region of Styria, ByeAgain assesses, repairs, cleans, grades and resells products on behalf of its clients through their own shops or online marketplaces, while the clients keep control of pricing and channels. It specialises in non-standardised goods such as baby and kids products, tools and DIY, outdoor and garden, and pet equipment, and uses AI-supported workflows to decide how each item is handled.

Why ByeAgain matters
ByeAgain matters because it addresses a cost that most online retailers carry but few manage well: returned goods that cannot simply go back on the shelf. Electronics have established refurbishment routes, but strollers, power tools or garden equipment differ item by item, which makes manual processing expensive. In the Startuprad.io interview Wolfgang Weingraber argued that refurbishment is a retail infrastructure problem rather than a sustainability story, that it becomes relevant from the first returned item, and that products below roughly EUR 20 retail value often do not pay for themselves. ByeAgain is therefore a practical case for retailers, logistics providers and investors looking at the economics of the circular economy, and for founders building operational businesses in high-wage markets.

Company
ByeAgain GmbH was founded in Styria in 2022 by Wolfgang Weingraber and Jan Kranner, according to the Styrian news service of the Austrian Economic Chamber, which in February 2025 described the company as a specialist in refurbishing used children's products such as strollers. The company began with a marketplace on which private sellers could have items refurbished and sold, and then moved mainly into business-to-business services. Retailers can either add a refurbished section to their own online shops or have ByeAgain sell through marketplaces; they pay a fee and keep the sales revenue. The process covers a function check, repairs, hygienic cleaning and a condition grade.

At that time the company reported about 750 parcels a month, roughly 55 percent going to Germany, 17 percent to Italy and 15 percent to France, and said it had worked with the refurbished-goods marketplace refurbed for four months, supplying its children's section. The Green Tech Valley cluster lists ByeAgain GmbH as a cluster partner with registered address in Fernitz-Mellach near Graz and Weingraber as chief executive and co-founder. The company's own website now presents refurbishment as a service at industrial scale for brands and retailers in Europe, lists an office in Graz, extends the category range to tools and DIY, outdoor and garden, and pet equipment, and names eBay, Cdiscount, Allegro, Amazon, refurbed and Kaufland as resale channels. In autumn 2026 ByeAgain was named Circular Start-up of the Year at the first Circular Innovation Award Austria. Funding details have not been published in the sources reviewed.

Role in the startup and technology landscape of Germany, Austria and Switzerland
ByeAgain sits at the intersection of e-commerce, logistics and the circular economy in the German-speaking markets. Online retailers in Germany and Austria face high return rates, and the European Union is moving toward stricter rules on product waste and the destruction of unsold goods, which makes managed resale more relevant. Because labour costs in Germany, Austria and Switzerland are high, refurbishment only works when handling time per item falls; ByeAgain's argument is that AI-guided decisions and standardised workflows can achieve this for categories that resist automation. For brands selling into Germany, its model offers a way to recover value from returns without building their own refurbishment operation. ByeAgain is also part of a visible Austrian cluster of circular-economy companies that includes the refurbished-goods marketplace refurbed, with which it works as a supplier.

Startuprad.io relevance
Startuprad.io interviewed co-founder Wolfgang Weingraber in March 2026 about the unit economics of retail refurbishment, why non-standardised goods are the hard category, who controls pricing and channels in a service model, and why labour costs in Germany, Austria and Switzerland make workflow automation critical. The entity links into Startuprad.io's coverage of e-commerce, logistics and circular-economy start-ups.
