Intro

"If we were building Box today, what would we do?” Ben Kus (CTO @ Box) deconstructs their playbook for enterprise AI innovation. We cover their journey to reimagine & reorient the company to a new technical vision, how they run a “multi-speed” org that balances startup agility and & enterprise-grade stability, and their “platform first” approach to build AI features. Ben also explains why security/compliance was foundational from "day negative one" in their AI strategy, the evolution of agentic AI, determining the right guardrails for AI agents & the future of multi-agent systems, enterprise trends & more.

ABOUT BEN KUS

Ben Kus is the Chief Technology Officer at Box, where he leads technology and AI strategy to help enterprises securely unlock insights from their unstructured data. Ben’s career spans engineering, product leadership, and startup innovation—including co-founding Subspace (acquired by Box) and being an early employee at BigFix (acquired by IBM), where he later served as Chief Architect of Mobile Security. Ben holds a degree in Computer Science from UC Berkeley.

ToolHive Unlocks the Full Value of MCP & Your AI Agents

So you’ve invested in AI agents for code generation, but they’re limited to experiments or even stuck on the shelf. To do real, valuable work, those AI agents need access to your data and systems.

ToolHive helps you confidently connect the pieces by making it simple and secure for you to use the Model Context Protocol (MCP).

ToolHive includes a pre-vetted registry of MCP servers, containerizes every MCP server for consistency and leans on built-in security to keep your secrets safe.

Leaders trust ToolHive to put MCP into production and put their AI agents to work.

ToolHive is open source, so get started for free at toolhive.dev
