Downstream is a Dallas-based online marketplace that lets construction contractors rent equipment, book waste hauling, and order jobsite services - dumpsters, porta potties, scissor lifts, forklifts, fencing, mobile offices - from a nationwide network of vetted suppliers. The platform delivers real-time pricing, multiple competing quotes per job, consolidated billing, Net 30 payment terms, and AI agents that read a contractor's rollout sheets or invoices to procure automatically. Founded in 2022 (originally as Trash Gurus), the company raised an $8M Series A in November 2025 co-led by Brick & Mortar Ventures and Moneta Ventures.
Tundra was an online B2B wholesale marketplace that connected independent retailers with brands across the U.S. and Canada on a zero-commission model. Founded in 2017 by Arnold and Katie Engel, it pitched itself as the friction-free alternative to trade shows and middleman markups, letting buyers source millions of products at true wholesale prices with low minimums, free shipping, and net terms. After raising roughly $38M from investors including Emergence Capital and Redpoint, Tundra grew to a community of 30,000+ retailers before winding down its marketplace in 2023 amid intense competition from Faire.
BlueTape is a payments and financing platform built for the construction industry. It gives material suppliers, manufacturers, dealers and contractors the tools larger firms take for granted - trade credit, net terms up to 120 days, buy-now-pay-later for building materials, automated accounts receivable, factoring, early-payment programs and lines of credit. The goal is simple: help small and midsize construction businesses get paid faster, sell more, and finance the materials they need without the paperwork and cash-flow crunch that has long defined the trade.
