São Paulo, March 23, 2026 – BackChannel, a B2B marketplace that uses Artificial Intelligence (AI) to connect Brazil’s small merchants to surplus inventory from major brands and distributors, announced it has raised US$4.75 million (BRL 25 million) in a seed round led by Sunna Ventures. Positive Ventures, SC Latam Innovation Fund, Preface Ventures, Norte Ventures, Accion Ventures, Savia Ventures, Ignia VC, and Morro Ventures also participated in the round.
According to the Brazilian Association of Waste and Environment (ABREMA), Brazil produces about 170,000 tons of textile waste annually, with 80% destined for dumps and landfills. At the same time, Brazil’s more than 16 million micro, small and medium-sized enterprises (MSMEs) are often unable to access high-quality merchandise from major brands, due to high prices and lack of financing.
BackChannel is a Brazilian B2B marketplace that enables small and medium-sized retailers to purchase high-quality surplus inventory from large consumer brands. Operating in the apparel and footwear space, the company connects manufacturers and distributors that struggle to manage unsold inventory with buyers who are interested in acquiring inventory at discounted prices. BackChannel’s platform is driven by a proprietary AI model, which optimizes the pricing, negotiation, and finalization of deals in real time. With this new round of funding, BackChannel aims to launch a new credit feature to enable small merchants to access the financing needed to purchase inventory.
“Our mission at BackChannel is to turn an often-invisible liability into predictable revenue. It’s not just about selling inventory, but about structuring liquidity with control, margin, and speed,” says Guillermo Freire, CEO of BackChannel.
“BackChannel is building a strong value proposition in a large, fragmented and historically inefficient market. The company helps brands monetize surplus inventory more efficiently and expands merchants’ access to products from major brands. We see a team with rare execution capacity, solid fundamentals, differentiated technology, and a model that also contributes to reducing inventory waste,” comments Luisa Sucre from Sunna Ventures.
According to Amee Parbhoo, Managing Partner at Accion Ventures, “Thousands of small and medium-sized merchants in Brazil face difficulties in accessing products from high-quality brands at competitive prices. We believe BackChannel creates an efficient bridge between supply and demand. By expanding access to new inventory, improving margins, and providing working capital, BackChannel seeks to significantly improve the competitiveness and resilience of small retailers by incorporating them into the circular economy.”
This funding follows a pre-seed round of US $3.2 million (BRL 17 million) in October 2024 led by Cathay Latam. BackChannel ended 2025 with an annualized gross merchandise value (GMV) of US$4.75 million (BRL 25 million), more than 300,000 items transacted and a base of more than 1,000 active buyers, maintaining an average growth of 30% per month.
