Misprint is an all-in-one marketplace that solves the biggest pain point in the collectibles world: opaque pricing. Collectors, investors, and hobbyists currently rely on scattered data from auction houses, online forums, and reseller platforms, making it difficult to know the true value of their items. Misprint streamlines the process by combining accurate pricing analytics with a seamless buy/sell marketplace, making it easier than ever to understand and monetize collectible assets. Existing marketplaces lack robust, real-time analytics because accurate valuations require deep expertise in both the collectibles domain and advanced pricing algorithms. Misprint’s unique blend of insider trading card knowledge and machine learning allows us to fill this gap. Building these pricing models requires extensive data infrastructure, deep domain expertise, and cutting-edge ML. Recent surges in the trading card market show that collectors crave transparent valuations. The global collectibles market is worth tens of billions of dollars. Eva has experienced the scale of this industry firsthand, generating $500k ARR within three months of taking her Pokemon card-selling side hustle full-time. With additional segments like sports cards, comics, and emerging collectible categories, the growth runway is immense. Co-founders Eva and Jon have been best friends since Exeter, combining finance expertise, a passion for collectibles, and mathematical rigor. By merging Goldman Sachs-level financial analytics with top-tier mathematical talent, Misprint is uniquely positioned to become the go-to platform for fair, transparent pricing in the collectibles space.

Oway is an AI-driven freight platform that turns America’s empty truck space into a new category of freight shipping. Every year 50% of U.S. truck space goes unused, a $100B+ inefficiency. Oway uses AI to automatically price, match, and sell that space in real time, giving businesses freight shipping that is dramatically faster and cheaper than traditional options. We're building the largest decentralized network of America’s empty truck space - a transparent infrastructure layer any shipper, broker, or carrier can plug into. For shippers, this means freight costs that are up to 50% lower than traditional LTL (shipments from 1 to 12 pallets), along with faster delivery windows because freight moves directly from dock to dock without the slow handoffs, warehouses, or cross-docking infrastructure that LTL depends on. For carriers, Oway’s integration can increase annual revenues by up to 30% with minimal impact on existing schedules. They simply earn more by monetizing space that would have gone unused. Our mission is to transform empty truck space into an asset that strengthens U.S. competitiveness. By lowering the cost of goods sold, we help businesses grow. By improving carrier margins, we make trucking more sustainable. And by digitizing and decentralizing freight, we are laying the foundation for a resilient, transparent logistics layer that can support America’s reindustrialization in the decades ahead. Oway makes freight shipping as simple as ridesharing - click a button, book a truck, and move goods at the true cost of available capacity.

The pandemic reduced office use nationwide by 50%, and tenants have been left to deal with highly inflexible, long term lease agreements that don’t fit today’s office use patterns.

Tandem is an AI-enabled office leasing platform. We’re using technology to unlock flexible agreements in quality spaces. Our AI co-pilot enables a white-glove-quality B2B office search experience, with a fraction of the human labor typically required.

At Matagora, our team brings over a decade of retail experience. Our mission is to empower independent retailers with the tools they need to compete with big box stores and effectively level out the playing field. One of the biggest challenges we see is staffing — many retailers struggle to maintain consistent, reliable, and properly trained team members to handle back-office tasks, marketing, ecommerce, POS management, and basic tech know-how. That’s why we offer affordable, ecommerce expertise as a service. Retailers no longer have to worry about high turnover, constant retraining, or trying to learn everything themselves. Instead, they can stay focused on what they love: curating great products and delivering an amazing in-store experience — while we handle the rest. And since it’s a simple expense, it’s easy to plan for and write off, too.

Small shop owners earn daily unlike salaried people but when it comes to loan repayment both are asked to pay monthly. For these shop owners it is difficult to calculate how much to save daily so that they will have the required installment amount at the end of the month and also at the time of repayment they have a big hole in their working capital. Therefore, when you earn daily why not pay daily and get away from the stress of huge one-time installments. Every day a small amount of $X is deducted from your digital wallet which is on the auto-debit mandate and you don't need to worry about keeping your balance of $XXXX. You never default and also good credit scores are created.

Sanvivo gives pharmacies software to take, fill and schedule delivery for online orders. We also bring instant demand through integrations with 3rd party consumer delivery companies.

Sanvivo uses technology to give local pharmacies digital superpowers, enabling them to combine fast supply and high-quality consultation with state of the are e-commerce solutions.
