Mineflow predicts the shape and location of mineral deposits

Mineflow is an AI platform for mineral exploration. We generate predictions for mineral deposit shapes and locations, empowering mining companies from initial exploration to advanced feasibility studies. Geologists need to know precisely where their deposits are because drilling is expensive. In early trials with a lithium mining company, we found that Mineflow predicts the shape of hard rock lithium deposits more than an order of magnitude more accurately than our competitors.

The Marketplace for Complex Hobbies

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.

Identify churn risk and stay close to users at scale

Minro helps companies stay close to their users as they scale. Today, most startups have thousands of product events flowing through tools like PostHog, but still have no real understanding of who their users actually are, which users are quietly about to churn, or what outreach actually brings them back. Founders care deeply about their users, but staying close to them becomes operationally impossible very quickly. Minro plugs directly into a company’s analytics stack and turns product activity into living customer intelligence. We enrich every user with context like their company, role, LinkedIn/GitHub/Twitter, background, and likely use case, currently matching users to the correct online identity with ~80% accuracy starting from just name + email. We then identify which users are most likely to churn based on behavioral patterns, persona similarity, and historical retention signals, and help founders proactively reach out before those users disappear. Minro drafts highly contextual founder-style outreach, tracks which conversations actually convert into retention, and continuously improves the system over time. The result is a customer intelligence and retention layer that helps companies understand their users better, build stronger relationships, and reduce churn before it happens.
