Value proposition
Provides persistent, hardware-isolated Linux virtual machines in the cloud that developers and AI coding agents can compose once, fork in under 200ms, and never pay for while idle — solving the state-loss and security problems of container-based dev environments.
Products and solutions
Composable cloud Linux machines (2 vCPU/8GB/100GB default) with live memory forking, snapshots, checkpoints, pause/resume/hibernate, use cases include development workspaces, preview environments, coding agents (Claude Code, Codex, opencode), personal assistants, sandboxes, agentic SaaS, reproducible RL environments, and agent swarm intelligence, CLI, API, SDK, and self-hosted options.
Unique value
Real KVM VMs (not containers) with live memory forking in <200ms, persistent state across sessions, and a stripped-down virtualization architecture that shrinks the attack surface for autonomous agents.
Target customer
Developers and engineering teams running AI coding agents (Claude Code, Codex, opencode), plus agentic SaaS and RL training teams needing persistent, isolated compute.
Industries served
Software development, AI/ML infrastructure, developer tooling
Technology advantage
Custom virtualization engine using stripped-down KVM VMs (CPU/RAM/storage/networking only, no emulated hardware like audio/webcam/USB) that shrinks the software attack surface; live memory forking in <200ms; persistent state with sub-millisecond resume from hibernation; credit-based billing with no idle cost.
How they differentiate
Unlike container-based alternatives that lose state and share kernel security risks, boxd offers hardware-isolated persistent VMs with live memory forking, so agents keep state between sessions and kernel exploits can't reach the host or neighbors.
Main competitors
Sprites (sprites.dev / Fly.io), Runloop, Niteshift, E2B, Daytona, Modal, Morph, exe.dev
Key partnerships
Integrations with GitHub, Linear, Slack, OpenAI Codex, Claude, OSS agent frameworks (Flue, Bindu, Harbor), ships Claude Code, Codex, and opencode in every machine.
Notable customers
Engineers at Meta, Google, Tesla, ByteDance, HelloFresh, Prosus, Booking.com, Techleap, FREE NOW, orq.ai, LangWatch, Duna, Sparqle, and others (individual engineers; not confirmed enterprise contracts)
Major milestones
Founded 2025 in Amsterdam, raised €2M pre-seed (Sep 2026) led by BlueYard Capital, launched public product with CLI, SDK, and self-hosted options, open roles in Amsterdam and Bucharest.
Growth metrics
5000+ builders on platform (pricing page); thousands of engineers using VMs (Sep 2026 funding announcement)
Market positioning
Early-stage player in the emerging "cloud infrastructure for AI coding agents" layer, competing with US players like Runloop and Niteshift from a European (Amsterdam) base.
Geographic focus
Europe (Amsterdam HQ, Bucharest engineering) competing against US-based devbox/sandbox providers
