NuSource

NuSource wasn’t made to sell secondhand. It was made for the people who do it best. In secondhand, store owners are often left behind, buried in bulk lots, stuck with inconsistent quality, and squeezed by pricing games that kill margins. We’ve been there. So we built something better. NuSource is the sourcing platform that puts store owners first. Every item is hand-picked, scanned, sorted, and transparently priced, so you get the inventory you want, minus the guesswork. Trending brands. Luxury surprises. Orders you can trust. Backed by real support from people who’ve been in your shoes. And it works because of how we source. We partner directly with brands, distributors, and retailers to transform their excess inventory into high-value resale opportunities, rather than liquidation. Our sales channel segmentation protects brand equity, ensuring that products reach the right audience at the right price while maintaining brand integrity. 🔹 What makes us different: • Brand-sorted inventory with real resale value. • Transparent, per-unit pricing. No scales. No games. • Custom order options tailored to your store. • Hands-on support from resale pros, not call centers. Behind NuSource is Jessica Rennard, a former reseller, Plato’s Closet buyer, and merchandising lead at Helpsy Source. After years inside the system, she saw its flaws firsthand and set out to build something better. In late 2024, she teamed up with investor David Lukrich of Angel Rush Ventures. Both believed the future of resale depends on empowering the people closest to it: The store owners. That shared vision led to the launch of NuSource as an independent company with a clear focus, making sourcing work for store owners and the partners who supply them. Early users already see the shift: 💬 “We’re finally getting trending inventory that moves.” 💬 “NuSource listens. We’ve never had sourcing support like this.” Coming Summer 2025 → nusource.io
