Advanced AI is radically transforming our world. Juniper supports founders making AI secure and beneficial for humanity.

We’re into assurance infra like energy, hardware, physical networking (hard), compute, security, audits (cloud), data, evals, interpretability (model), inference, guardrails, observability (runtime), authentication, agents, integrations (distribution), compliance, insurance, policy (governance).

We steward Tehama (tehamastreet.xyz), publish the AI Assurance Technology Report (aiat.report), and maintain the AI Neolab Tracker.

We love working with founders.
