Nessie
A shared context layer for you, your team, and your agents.
Knowledge work is being restructured by AI. Strategy happens in Claude. Research happens in ChatGPT. Building happens in Claude Code. The people defining the next decade of work are already thinking with AI every day. But none of that thinking compounds. Every session starts from zero. The reasoning behind decisions, the context behind strategies, the evolution of ideas across hundreds of conversations - all of it evaporates. Nessie is the infrastructure that makes it permanent. We auto-sync AI conversations and agent traces across every major provider - ChatGPT, Claude, Gemini, Perplexity, Claude Code, OpenClaw, Codex, and more - and turn them into a context layer that is queryable, reusable, and shareable by you, your team, and your agents. No browser extension. No manual capture. Your thinking flows in automatically and compounds over time. Where we are going: the AI-native organization runs thousands of agents that are powerful but amnesiac, and Nessie is the layer that integrates what the organization knows, what it has decided, and how its thinking has evolved. Science has journals, law has case law, software has git; AI-native knowledge work has had nothing. We are building it. We are two Yale CS grads and former Amazon engineers. Backed by BoxGroup, Pioneer Fund, Y Combinator, Precursor, and more. https://nessielabs.com

Nestybox
Enables Linux containers to act as super fast & efficient VMs
Nestybox creates software that enables Linux containers to act like virtual machines. This increases the use cases for containers and gives enterprises a less expensive and more flexible alternative to virtual machines in many scenarios. Our first product is a "container runtime", the software that creates the containers. It's called "Sysbox" and integrates with the popular Docker and Kubernetes engines, enabling these tools to deploy containers that act like virtual machines. This technology provides software engineers with an alternative to VMs, one that easier to use, much more efficiency, and easily migrated across clouds.

Netter
AI native Palantir for mid market.
Netter (YC P26) helps companies regain control over their data, so teams can pilot their activities with high precision. Most companies are sitting on years of valuable data, spread across different formats and disconnected tools that don't talk to each other. Netter brings technical capacity to companies that don't have an army of data engineers, and tackles their most complex data challenges. - A nursing home group was chasing unpaid invoices manually across disconnected tools. Netter centralized the collection workflows, automated reminders, real-time visibility, task routing. - A retail chain had years of loyalty card data sitting unused. Netter cross-referenced it with public demographic data to build precise customer segments and trigger the right promotions to the right people.

We build floating solar data centers

Neuromorphic
Building robots to automate wetlabs
We are building robots that can work autonomously in existing wet labs. Unlike traditional lab automation, which requires dedicated equipment and fixed workflows, our robot moves between workstations, manipulates existing scientific equipment, transports lab materials, and executes experiments using the same lab infrastructure as a human technician. We make the robots easy to manage through natural interfaces like Slack, email, and phone. Our goal is to make deploying robots in wet labs as easy as onboarding a new employee, and to accelerate scientific research!
