Vobi
Vobi is a Sao Paulo-based, all-in-one project and construction management platform for small and midsize construction businesses across Latin America - contractors, remodelers, architects and engineering firms. It rolls estimating, budgeting, scheduling, a client portal, purchasing and payments (Vobi Pay) into one system, with AI agents for finance, procurement and work diaries. Backed by Y Combinator (W22) and MAR Ventures, the platform says it manages over R$5 billion in construction projects annually.
Downstream
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.
Bobyard
Bobyard is a San Francisco AI company that automates construction takeoffs and estimates. Its proprietary computer-vision and NLP models read blueprints and automatically count symbols and measure areas and lengths, cutting bid-prep time by more than half. Founded in 2023 by Michael Ding, the company started with landscaping - one of construction's least-digitized trades - and has expanded into electrical, finishes, mechanical, and plumbing. It raised a $35M Series A led by 8VC in December 2025.
BlueTape
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.
Kojo
Kojo is the construction industry's leading materials procurement and management platform, connecting office teams, field crews, warehouses, and vendors on a single AI-powered system. Founded in 2018 by Maria Davidson (formerly known as Agora Systems), the San Francisco-based company has powered more than 10,000 construction projects across 47 states and processes billions in annual orders for trade and self-perform general contractors.
