Tailscale

About

We're building a new kind of network that returns to the original vision of the Internet - one where creating secure connections is simple and accessible to everyone. We're a fully remote team spread across the United States, Canada, and the United Kingdom, working together to remove the overhead and complexity of building trusted, secure networks. Whether you're connecting devices for a family photo share or securing infrastructure for a multinational corporation, we believe networking should be safe, understandable, and practically invisible.

Our team is guided by a few core beliefs: that small, excellent teams produce better outcomes than massive ones, that technology should just work without constant fiddling, and that privacy is fundamental. We built Tailscale on WireGuard with end-to-end encryption, so we can't see your traffic - because we don't want to. We're committed to open source, transparent security practices, and building a product that scales with your needs without scaling the operational headaches. Every day, we're working to make connectivity easier and more secure for teams of any size.

NS

Nscale

We're building the infrastructure that powers the next generation of AI. At Nscale, we provide a full-stack, sovereign, and sustainable AI cloud platform that enables practitioners, enterprises, and governments to create, deploy, and scale their most transformative AI systems. Our team comes from deep backgrounds in high-performance computing, data center design, and AI infrastructure, and we know firsthand how challenging it is to build at this scale. What makes us different is our fully vertically integrated approach. We own everything from the data centers to the GPU clusters to the orchestration software, which means we can deliver cost-effective, sustainable AI infrastructure at a scale that's simply not possible with the traditional neocloud model. Since launching in 2024, we've expanded our pipeline across Europe and North America to 1.3GW, and we're just getting started. We're builders shaping the future of AI, and we're looking for people who want to own their work, move fast, and build with trust.

Join us if you're energized by building technology that accelerates humanity's most important innovations. What makes Rescale unique is how we blend deep domain expertise with modern cloud-native development. Our platform runs on AWS and Azure, leveraging Kubernetes, CUDA, and containerization to deliver seamless HPC experiences. We build with Python, Django, React, and TypeScript, creating tools that scientists and engineers actually want to use. But our true differentiator is our collaborative spirit - frontend engineers pair with HPC specialists, data scientists work alongside product managers, and everyone has a voice in shaping our roadmap. We optimize for focus and autonomy, not facetime. Whether you're specializing in AI physics, backend performance, or simulation engineering, you'll find teammates who challenge you to grow while supporting your success.

SellScale

SellScale is building the first Agentic Revenue Org, starting with Selix - an AI Agent designed specifically for the sales floor. The company's mission is to help businesses grow by bringing Artificial General Intelligence to the non-technical workforce, starting with the hardest workflow to crack: cold outreach. SellScale believes that the future of sales is human x machine, where AI agents work alongside sales teams to scale outbound efforts in ways that purely human-driven processes cannot match. The team is deeply technical and agent-focused, having worked on agentic AI systems since 2024. They're backed by leading investors including Pear VC, Ovo Fund, and growth leaders from companies like Notion, Athelas, Ramp, Figma, Moveworks, and Clay. Based in San Francisco, SellScale operates as a tight-knit team that values in-person collaboration, shipping across the stack, and solving complex problems at the intersection of AI and enterprise sales.

OP

OptoScale

OptoScale provides real-time monitoring and precise measurements for the aquaculture industry through their innovative Bioscope technology. The company's underwater imaging systems and AI-powered software enable fish farmers to track weight, sea lice, health indicators, and feeding behavior without manual handling - reducing stress on fish while delivering actionable data that improves decision-making. By replacing manual sampling with automated, continuous observation, OptoScale helps operators optimize production, reduce costs, and enhance fish welfare. Founded in 2015 and headquartered in Trondheim, Norway's technology capital, OptoScale has grown from a local startup to an international player operating across seven countries. Their multidisciplinary team combines expertise in physics, mathematics, cybernetics, marine technology, software engineering, and biology to deliver robust, precision measurement tools. The company's mission-driven approach centers on advancing responsible aquaculture through technology that prioritizes sustainability, efficiency, and animal welfare - transforming how salmon and rainbow trout are monitored and managed worldwide.

ST

Steer

Steer exists to solve a fundamental problem in the auto repair industry: customer retention. Every day, auto repair shops lose thousands of dollars in revenue not because they lack skilled technicians or fair prices, but because they fail to stay connected with customers after the first visit. Shops manually chase bookings, struggle to get reviews, and waste hours on follow-up that never happens. This disconnect costs independent shops an estimated $50 billion annually in unrealized revenue. Steer gives auto repair shops the tools to turn every customer into a repeat customer. The platform combines CRM essentials like online scheduling, automated service reminders, and two-way messaging with revenue-driving features including text and email campaigns, review management, and direct mail. In 2024, Steer merged with AutoOps, uniting the industry's leading CRM and scheduling tools into one powerful platform. With a remote-first team spanning Waltham, Massachusetts and Lviv, Ukraine, Steer serves thousands of shops across North America, helping owners build lasting customer relationships through automated, intelligent communication.
