ConstructionYardSale.com is a marketplace built specifically for DIYers, contractors, remodelers, and construction professionals to buy and sell leftover and surplus building materials. We solve a massive industry problem: every year the U.S. construction industry generates over 600 million tons of waste, much of which is still perfectly usable lumber, tile, tools, drywall, and equipment. Instead of throwing valuable materials in the dumpster, our platform lets contractors quickly turn job-site leftovers into cash through fast, local pickup. What makes us different: - Secure escrow payments with PIN code verification at pickup — no risky cash exchanges - Purpose-built for construction professionals with smart search, quantity-based buying, and mapping - Tiered plans (free Basic, Pro at $49/mo, and Enterprise at $149/mo) designed around real contractor needs - Focused on speed, trust, and simplicity We are currently in final development and plan to launch on August 15, 2026, starting in the Northeast before expanding nationally. Our mission is to reduce construction waste, lower material costs for builders, and create a true circular economy in the construction industry.

FairwAI is building real-time accountability infrastructure to detect bias in the moments that matter most. We’re solving one of the toughest challenges in tech: how to make fairness not just a principle but a system. From healthcare and hiring to hospitality and housing, bias shows up when people are most vulnerable. FairwAI turns those moments into measurable, actionable data—using AI, computer vision, and behavioral science to flag risks and enable institutional change before harm happens. We’re not a DEI tool. We’re compliance infrastructure for a new era—where safety, dignity, and fairness are non-negotiable. Our team includes engineers, policy thinkers, civil rights advocates, and public interest technologists from MIT, Harvard, Stanford, The UN, and beyond. We’re launching high-impact projects and building the backbone of ethical AI adoption across sectors. For interns & fellows, this is not a coffee-run experience. You’ll co-design tools, analyze live scenarios, and help shape the future of bias detection and remediation. Your work will be mentored, respected, and turned into real-world impact. If you care about fairness, ethics, and building tools that actually change lives—FairwAI is where your skills meet purpose. Join us. Let’s build the infrastructure fairness deserves.
