Miniswap a marketplace for complex hobbies, starting with Warhammer. In hobbies as complex as Warhammer, finding what you want on general marketplaces is a huge pain. Filters don't work, free-form listings mean that products are regularly misidentified, and piles of counterfeit junk crowd search results.

Sellers match their listings against Miniswap's catalogue giving buyers more information and structure as they shop. The global market for tabletop games is estimated to be worth $20B in 2025 and Warhammer alone is projected to grow to $3B by 2030.

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.

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 builds a multisided platform to enable customers to order medications, get pharmaceutical advice, and book health services at local pharmacies in Europe. Just like Shopify for pharmacies. 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. Almost all pharmacies in Europe are, by law, local 1-person businesses. And they are not ready for online orders.

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.

Ultra-high net worth individuals spend $390 billion per year ($1.3 million each) on lifestyle, but they still struggle to find everything they want. Why?

Attain is a one-stop shop for convenience store owners to buy inventory across all their suppliers with higher reliability, price transparency, and product discovery. On average, store owners buy products from over 10-15 different suppliers each week. This painful process involves shopping in massive warehouses or spending hours working with wholesaler’s sales representatives (who sometimes don’t even show up). As a result, stores waste countless hours ordering products through extremely inefficient and tedious processes. These store owners are also severely impacted by inventory shortages and revenue loss which many times results in them downsizing their business or shutting them down completely. Attain solves this problem by providing a single app to purchase products across all of their suppliers, resulting in a one-stop shop for inventory. By aggregating inventory across a multitude of suppliers and wholesalers, Attain helps stores save significant time and money while allowing them to focus on what they do best - growing their businesses. Feel free to reach out at founders@joinattain.com!
