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. Miniswap saves hobbyists from this chaos with its catalogue of more than 20,000 unique miniatures. 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. By capturing the market in this untapped niche, Miniswap is strongly positioned to bringing greater transparency, simplicity, and connectivity into adjacent verticals. Miniswap's founding team merges deep domain knowledge with elite programming expertise and years of experience in business consulting and startups. Co-founders Zak and Will met while studying together at Cambridge, bonded over their love of Warhammer and early modern history. They have been best friends ever since.

The cloud marketplaces on AWS, Azure, and GCP have become the App Store for B2B software products. It’s growing close to 100% year-over-year since it gives software sellers access to cloud budgets and makes procurement 40% faster. The core problem is the cloud marketplace is hard to navigate and requires an upfront technical investment without knowing the expected ROI. Suger eliminates the need to reinvent the wheel with your own engineering resource or spend a fortune on consulting-based solutions.

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!

Over 70% of B2B trade still happens through emails, PDFs, texts, and phone calls — not because companies prefer it, but because their customers do. This is the default ordering workflow across industries, and despite decades of ERP software, it remains largely manual. Response provides the infrastructure for this reality. We turn unstructured customer messages into ERP-ready draft orders, so teams can review, approve, and move faster without changing how they work. By automating the space between customer intent and systems of record, Response lets operators scale order volume without hiring more people, outsourcing labor, or retraining customers. We’re building the missing action layer for how B2B trade actually works.

At Extern, we’re solving the experience gap. Extern created the remote Externship, a skill-building work experience that is easier for students to access, and easier for companies to run, than an internship. Our mission is to help anyone discover and launch their career through professional experiences available anywhere at any time. Since 2020, we’ve created and powered Externships for over 50,000 students on behalf of companies from Fortune 500s to startups. After spending $100K on average for a 4-year degree, graduates find that almost 40% of entry level jobs on Linkedin required 3+ years of work experience. Internships are how many college students get this kind of experience, but the demand for good internships outstrips the supply. Internship programs are difficult to scale, they favor students who already have social capital, and they’re time-consuming for employers to run. Externships are short, online, project-based work experiences that employers can offer to hundreds of students using less resource and employee time than it would take to support an intern. Extern makes the complex process of running an Externship completely turnkey with software and industry experts which in turn makes professional experience more accessible to more students. By making work experience more accessible, Extern is driving the rapid mobility and upskilling needed for a new economy. We envision a world where anyone can access work experience as a form of education – no matter their background, experience, or socio-economic status. Come join our movement to reshape work, education, and credentialing for future generations with the Externship. Extern was born out of a pivot from Paragon One (W17) which initially focused on providing students with a career center-as-a-service platform, connecting them with industry professionals to receive career coaching and guidance. Backed by Y Combinator, Foundation Capital, Launch Fund, University Ventures, and Learn Capital.

We’re on a mission to optimize the agricultural industry. When we started Bountiful in 2015, the grape error rate for predicting production was 30 percent. Why? We found that many farmers in the specialty crops space were still using traditional pencil-and-paper techniques to predict yield. These low-fidelity forecasting methods weren’t giving them a clear enough understanding of their production until it was too late, leading to waste and inefficiency throughout the supply chain. We saw a problem we wanted to solve. Today, Bountiful is using advanced data science to help farmers forecast more accurately, so they can make better decisions. In the last three years, we’ve combined the latest in machine learning with weather, satellite, geographic, and historical data. The result is a user-friendly platform that transforms volumes of complex agricultural information into simple, actionable insights farmers can use to run more economically and environmentally sustainable farms. More recently, we’re working to open the dialogue between buyers and sellers, remove uncertainty, and provide clarity to the supply chain to meet global food demand. Our ultimate goal is to close the agricultural margin of error. Not only will this make individual farms more efficient, profitable, and sustainable, but it will help optimize the global food supply chain. That means healthier people and a healthier planet.
