Uplane (YC F25) replaces marketing agencies with AI. We generate hundreds of ads with matching landing pages and steer the ad spend across channels like Meta, Google, LinkedIn and others. By connecting to CRM and ERP data, Uplane learns what drives profits and continuously improves campaigns. Companies waste billions on bad ads, mismatched landing pages, and poor budget allocation. Uplane fixes this by replacing a patchwork of agencies, spreadsheets, and siloed tools with one self-improving system. The result: Higher ROAS for enterprises and effortless, expert-level marketing for SMBs.

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.

Art of Sports is building the AI operating system for ballet and dance studios across Europe. The foundation is 12 years of operating ballet studios in Germany: a Vaganova-certified methodology, students placed at two of Germany's top ballet academies (John Cranko School Stuttgart, Staatliche Ballettschule Berlin), and firsthand knowledge of what studios, teachers, parents and kids actually need. What we're building, in order: a structured digital curriculum (12 years of methodology turned into machine-readable content, tagged by exercise, level, terminology, errors and corrections), a Voice-AI layer for hands-free retrieval mid-class, large-format LED screens as the central teaching tool, and from year 2 the hard part: real-time AI movement correction for children learning ballet. Why now: pose estimation has become fast and reliable, but everyone is pointing it at home fitness mirrors and rep counting. Nobody has combined it with real pedagogy. Studio software today manages schedules and payments; it doesn't teach. The teaching layer, content, correction, progression, is empty space, and it's where the value sits. The methodology is the product; the technology is the delivery. Our wedge is the kids segment, an underserved niche in Europe, delivered B2B through studios: 7,450+ potential installations across dance, martial arts, kids fitness and school markets. The pilot studio launches in Frankfurt on August 15, 2026. LED manufacturer partnership talks are active, grant applications (EIC Accelerator, Creative Europe) are in progress. Honest stage: pre-funding. The methodology, the pilot and the partner pipeline are the assets. The platform gets built now, and we're looking for the founding CTO to build it.
