Castari: AI agent platform providing a managed environment to deploy and run AI agents for teams and businesses, focused on secure deployment.
Key people at Castari.
Castari was founded in 2025 by Jacob Wright (Founder) and Cambree Bernkopf (Founder).
Castari is a San Francisco, California-based artificial intelligence infrastructure startup that provides a managed platform for deploying and running AI agents within secure, sandboxed environments. Often described as a Vercel-like solution for AI agents, the platform enables software engineering teams to import projects built with the Claude Agent SDK and deploy them using a single command. The system provides built-in guardrails, auto-scaling capabilities, comprehensive logging, and controlled access to external utilities such as Model Context Protocol (MCP) skills. Operating with a small team of three employees, the early-stage company is currently offering its product through a private access model for enterprise automation and developer tooling customers. The startup is backed by the prominent accelerator Y Combinator and is participating in the firm's Fall 2025 batch. Castari was founded in 2025 by Cambree Bernkopf and Jacob Wright.

Castari is a cutting-edge platform that enables teams to deploy sandboxed AI agents quickly and securely, functioning as a "Vercel for AI agents." It provides a production-ready runtime environment specifically designed for AI agents built on the Claude Agent SDK, allowing developers to write agent logic and deploy it with autoscaling and sandboxing out of the box. This solves the common problem of fragile, complex infrastructure setups that hinder AI agents from moving beyond demos to reliable production use. Castari primarily serves AI developers and product teams building internal workflows or core AI-powered products that require secure, scalable agent execution[2][7].
For an investment firm perspective, Castari represents a mission-driven startup focused on enabling the next generation of AI infrastructure, with a philosophy centered on simplifying AI agent deployment and scaling. Its key sector is developer tools and AI infrastructure, impacting the startup ecosystem by accelerating AI agent adoption and production readiness, thus fostering innovation in AI applications and automation[1][2].
Founded in 2022 by Jacob Wright and Cambree Bernkopf, Castari emerged from the founders’ direct experience scaling AI consumer apps to millions of users and facing challenges in deploying AI agents reliably in production. Wright previously led the Frontend Engineering team at RunPod, and both founders recognized the need for a dedicated runtime for AI agents, analogous to how frontends have their own runtimes. This insight led to building Castari as a layer above existing sandbox and compute primitives, focusing on wrapping Claude Agent SDK-based agents in secure, autoscaling sandboxes without requiring teams to manage sandbox lifecycles themselves[2].
Early traction includes recognition as a Y Combinator W25 company and backing by prominent investors, reflecting confidence in their vision to become the natural runtime for AI agents[1][2].
Castari rides the wave of AI agent proliferation and the growing need for robust AI infrastructure. As AI agents become more complex—executing code, interacting with tools, running for extended periods, and handling sensitive data—the demand for secure, scalable runtimes grows. Castari addresses this by providing a dedicated production environment that abstracts away fragile infrastructure concerns, enabling AI agents to move from experimental demos to reliable, scalable products.
The timing is critical as enterprises and startups increasingly embed AI agents into workflows, products, and services, creating a market ripe for specialized infrastructure solutions. Castari’s approach influences the broader ecosystem by setting a standard for agent runtime environments, fostering faster innovation cycles and safer deployments in AI applications[2].
Looking ahead, Castari is well-positioned to become the go-to runtime platform for AI agents, especially as the Claude Agent SDK and other frameworks gain adoption. Future trends shaping its journey include the expansion of AI agents into diverse industries, increasing demand for secure and compliant AI infrastructure, and the evolution of multi-cloud and edge computing environments.
Castari’s influence is likely to grow as it enables developers to build more sophisticated, reliable AI agents without the burden of complex infrastructure management. This could lead to broader AI adoption across enterprises and startups, accelerating AI-driven automation and innovation.
In summary, Castari is building the foundational runtime that AI agents need to thrive in production, echoing the transformative impact Vercel had on frontend development[2][7].
