Reformly is a fast-growing DTC home Pilates brand operating across e-commerce and mobile. In our first 10 months, we generated over $4M in sales and built an app with 3,000+ active subscriptions. Our core audience is middle-aged women who want to feel stronger, healthier, and more confident, but often struggle with consistency. We help solve that by combining a physical Pilates board sold internationally with a mobile app that offers workouts, structure, and community. We are building more than a product. We are building a brand and ecosystem that helps women create a fitness routine they can actually stick to. Our mission is to help women become the best version of themselves. Our team is young, ambitious, and moves fast. We are not looking for people who want to coast, play it safe, or settle for “good enough.” We want people who care deeply about doing great work, want to achieve greatness in their career, and genuinely believe in what we are building. At Reformly, there is a lot of room for growth, ownership, and speed. We value initiative, decisiveness, and learning through action. We would rather make the wrong decision with conviction, learn fast, and improve, than make the right decision too slowly and without courage. If you want real responsibility, a steep learning curve, and the chance to help build something meaningful at speed, you’ll feel at home here.

Infrawatch is building the world’s first real-time adversary infrastructure intelligence platform - turning the global internet into a live, high-fidelity map of malicious networks, proxies, and command-and-control servers before they’re ever used in attacks. Every day, Infrawatch scans the entire public IPv4 and IPv6 space, generating over 150 million actionable indicators. Our proprietary rule engine and enrichment pipeline transform raw internet telemetry into curated, analyst-ready intelligence that powers fraud prevention, threat detection, and national-scale defence. Existing tools are fragmented: broad but shallow, or narrow but blind. Infrawatch unifies them. We give defenders visibility and attribution across all categories of adversary infrastructure, enabling them to block threats at the infrastructure stage - not after the breach. Our mission is simple but urgent: to be the infrastructure intelligence source of truth that keeps enterprises, governments, and critical systems ahead of adversaries. Built by defenders, for defenders, Infrawatch delivers unmatched coverage, precision, and speed. From cybersecurity giants to government agencies, organisations rely on Infrawatch’s live data feeds, APIs, and platform to identify malicious infrastructure, prevent fraud, and accelerate investigations. We care deeply about clarity: in data, in design, and in purpose. Our analyst-first platform makes billions of events feel effortless to explore, with modern workflows and visualizations that help teams see faster, decide smarter, and act sooner. We’re a small, focused, and remote-first team of engineers and researchers obsessed with quality, performance, and craft. Together, we’re building the backbone of proactive defence, a system that turns chaos into signal and helps the world beat the adversary.
