| Oway is a rideshare freight platform that uses AI to automatically coordinate and sell unused space in trucks to businesses at up to a 50% discount compared to traditional LTL freight shipping. It's a $100B problem in the US alone, with every year up to 50% of all the truck space in the country going empty or unused despite massive supplychain shortages.The American logistics industry is extremely fragmented with little automated coordination between carriers. Oway focuses on building an ecosystem that takes inefficiency (unused truck space) and turns it into a decentralized shipping platform that enables significantly faster and cheaper deliveries for small batch freight shipments up to 12 pallets. For carriers, integrating Oway can immediately increase annual revenues by up to 30% with almost no impact to existing delivery schedules.In a technical sense, Oway applies stochastic spread optimization and real-time liquidity modeling to dynamically price freight shipments, effectively functioning as a decentralized market maker optimizing expected value across variable supply constraints. It provides a simple UI and API for businesses to leverage this tool for any means. | $4M / Seed / Aug 22, 2025 | ||
