First principles.Shipped systems.
An independent research lab transforming complex challenges into elegant systems through research-driven innovation and human-centered design.
Areas we
work in.
We are not a traditional agency or a passive fund. We operate as an independent research lab embedded with founders, approaching every problem across six connected disciplines.
Exploring foundational questions in distributed systems, hardware-software co-design, and applied cryptography before turning them into working software.
Building agent runtimes, long-horizon coding harnesses, and reinforcement-guided workflows that operate reliably alongside human engineers.
Designing full-stack developer primitives—authentication, multitenancy, machine identity, webhooks, notifications, and framework adapters.
Taking internal lab prototypes all the way to independent software products and partnering closely with founders on hard technical problems.
Architecting low-latency network services, custom memory management in Rust, and real-time event and analytics pipelines.
Maintaining open-source stacks, SDKs, and developer tools so teams can inspect, self-host, and extend the infrastructure they depend on.
Current work
in flight.
Products researched, built, and operated in-house—open for design partners and early access.
Open-source infrastructure for AI-native apps
Identity & authentication, B2B multitenancy, machine auth, webhooks, notifications, and an AI agent runtime built as one platform on a single shared user and organization model.
Replaces the vendor stack teams otherwise stitch together by hand. Available self-hosted or in the cloud, with SDKs for Next.js, React Router, TanStack Router, Node, and Rust, plus prebuilt UI components.
Passwordless, passkeys, MFA, OAuth, SAML SSO, custom domains, and prebuilt React sign-in and account components.
B2B workspaces, invitations, roles and permissions, domain auto-join, and per-organization configuration.
API key management, OAuth-style scopes, machine identities, and per-tenant rate limiting.
Webhook endpoints, signed payloads, at-least-once delivery, automatic retries, and event replay.
Email, in-app inbox, and realtime notification streams with drop-in bell and panel components.
Persistent actors, threads, projects, board items, scheduled tasks, sandboxed compute, and approvals on tool calls.
Research to
production.
Selected
collaborations.
Alongside our own products, we partner with engineering teams to solve high-scale infrastructure, deliverability, and applied AI challenges.
Notes from the
research bench.
Writing
We take a small number of design partners each quarter for hard engineering problems.
