WRTH: The Agentic Commerce OS for Real World Assets At WRTH, we are building the world's first vertical AI-native commerce intelligence layer for physical assets. While e-commerce has Shopify, the $475B collectibles and alternative asset market still relies on fragmented spreadsheets and disconnected legacy tools. We are changing that. WRTH operates at the intersection of physical commerce, blockchain infrastructure, and agentic AI. We act as an Agentic Commerce Operating System (OS), deploying a vertical data layer that bridges the gap between real-world assets and on-chain records. Our platform replaces disjointed workflows with a unified system featuring real-time AI pricing intelligence (the WRTH Oracle), automated omni-channel cross-listing, and immutable provenance tracking via smart dual RFID/NFC tagging. We cure the "listing tax," eliminate overselling, and turn static physical inventory into intelligent digital assets. WRTH was built from lived experience, not theory. Our founders spent over 15 years in the trenches of the resale ecosystem, scaling seven-figure businesses from car trunks to top-tier digital storefronts and managing high-volume enterprise commerce. We built the platform we always needed. Today, WRTH is in an active closed beta, managing a committed pipeline of over $100M in Assets Under Management (AUM) alongside 35 B2B partners, including retail stores, event organizers, e-commerce power sellers, and brands. We are a lean, fast-moving pre-seed startup. Our culture reflects the hustle of our users and the precision of our technology—valuing autonomy, candid communication, and unconventional problem-solving. We are aggregating the transaction signals of the physical asset economy to build an unassailable intelligence flywheel. If you are a builder, advisor, or investor ready to shape the future of real-world asset commerce, join us. Let's build something WRTH it.

Viewlocked is an AI-powered travel planning and booking marketplace connecting travelers with verified local partners across stays, experiences, guides, tours, rentals, transportation, and local services, all in one place. We built Viewlocked to solve a simple problem: planning a trip today means juggling a dozen different platforms just to book a hotel, find a tour, rent a scooter, and hire a local guide. Nothing talks to each other, and by the time travelers discover the best local experiences, they're often already locked into their plans. Our AI assistant, VLX, changes that. Travelers build their trip, and VLX surfaces relevant partners in real time based on their dates, destination, and preferences, letting them discover and book everything directly within their itinerary before they even arrive. We officially launched in June 2026 and have already onboarded 60+ verified partners across 15+ countries, with zero paid marketing spend. We've been featured in Travel Daily News International and Travel and Tour World, and we're actively building a global network of travel partners as we scale. For travelers, Viewlocked means one platform for the entire trip. For partners, it means visibility at the exact moment traveler intent is highest, with structured bookings and a simple, transparent commission model. We're a small, fast-moving founding team building something we believe travel has been missing for a long time. If you're passionate about travel, startups, or building at an early stage.
