We build supply-chain security that protects every device from chip to cloud. Fortune-100s and federal agencies run us in production.

Ecosmic is on a mission to reduce threat exposure in space by building software for Space Situational Awareness. To achieve this, we built a team of flight dynamics engineers and computer scientists to build & package in-house algorithms into easy-to-use, reliable, and secure products. As an example, our platform recently allowed us to identify a series of close approaches in GEO involving Russia's Luch/Olymp-2 and a Western telecommunications satellite, possibly attributed to SIGINT activity. We're hiring a Senior DevOps Engineer (mid-level candidates are welcome too!) to aid the effort of unlocking on-premises deployments of our algorithms with Kubernetes, and to contribute to the evolution of our platform. Our stack includes Python for backend services and high-level algorithm tooling, C++ for performance-critical components, AWS for cloud infrastructure, and Terraform for IaC. We currently use managed serverless services, and we’re beginning a gradual migration from C++ to Rust for its reliability guarantees. You’d join a team of three software engineers who love working in such a fantastic domain. I currently take care of most of the infrastructure work with the team, and we’re looking for someone who can help us tackle this new challenge.

Edge Impulse is the top developer platform for edge AI, similar to HuggingFace but for models that process sensor data on the edge. They have a large and active community of hundreds of thousands of developers and were recently acquired by Qualcomm, who have a vision for bringing AI within reach of every embedded engineer.

EdgeDB is an open-source database built on top of Postgres, designed to give developers a better end-to-end user experience than traditional SQL databases. It offers a more expressive schema modeling & query language (EdgeQL), built-in schema migrations, a graphical schema browser, data explorer, and access control/auth. They provide a hosted cloud service aimed at developer-friendly cloud hosting.

We are a team of ~20 people, building open source software to make confidential computing more usable. Our products span unusually far across the tech stack, starting at measured boot, through Kubernetes operators, finishing somewhere in our JavaScript frontend.

Edlink is a small, high-performing team building the data infrastructure that powers edtech. Our API helps 60M+ students and educators access the software they need to teach and learn. We solve hard problems — messy school data, ancient SIS platforms, massive scale — and we do it without red tape, meetings about meetings, or fluff.

Edmij is a Climate Tech scale-up focused on electrifying the Dutch energy market. Using classic and machine learning methods to forecast weather patterns, electricity usage, and energy market dynamics, we efficiently allocate energy production and consumption for our clients. Our steering algorithms for solar panels, turbines, and batteries maximize green-energy production and consumption in the Netherlands, alleviating the pressure on an overloaded energy-grid. We are very profitable, allowing us to take a long-term view.

At Edra we built a new, proprietary method of learning that allows LLMs to understand and automate business processes. Founded by Eugen and Yannis, former co-heads of Forward Deployed AI Engineering at Palantir. We believe that as we get closer to AGI, the ability to teach models what you want them to do will become the key bottleneck in deployment to enterprises, and traditional training approaches won’t cut it. We named the company Edra for “the seat of the teacher”. Edra AI is a novel learning system, deployed with several customers and are looking to scale up. Backed by top-tier investors from the Palantir ecosystem with offices in New York and London.

Eedi is an edtech startup. We make software that helps children learn maths. We've secured a $12M grant from a prestigious US foundation and partnered with major education providers and other big (household name) companies. Our mission is to sustainably improve learning outcomes for 1 billion students by 2030.

EggAI is at the forefront of enterprise AI, building scalable, async-first backend systems and modern AI architectures.
