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.
