BAND, a company building an interaction layer for multi-agent systems, announced its launch out of stealth alongside a $17 million seed funding round backed by Sierra Ventures, Hetz Ventures, and Team8. The funding will be used to expand the company’s engineering team, accelerate product development, and grow its ecosystem of early design partners.
BAND is addressing a growing infrastructure challenge as enterprises deploy increasing numbers of AI agents across workflows in engineering, security, and operations. While adoption is accelerating, coordination between agents remains a major bottleneck. Many organizations still rely on manual processes to pass context between systems, resulting in fragmented workflows and brittle integrations that are not suited for production-scale automation.
The company’s platform introduces a unified interaction layer that enables agents to communicate, collaborate, and operate together in real time across frameworks, clouds, enterprises, and environments. This includes compatibility with agents built using frameworks such as LangChain and CrewAI, as well as third-party SaaS agents, coding agents, and personal AI assistants.
BAND’s approach allows agents to discover one another, exchange context, delegate tasks, and coordinate workflows without requiring extensive reconfiguration or custom integration work. By transforming agents from isolated tools into coordinated systems, the platform aims to unlock more scalable and reliable enterprise automation.
The platform includes several core capabilities designed for enterprise deployment:
- A shared architectural layer for multi-agent systems
- Structured communication and task delegation with preserved context
- Cross-framework interoperability without rewriting agents
- Human-in-the-loop oversight for inspection and intervention
- Agent discovery across internal and external environments
In addition, built-in governance tools provide visibility into agent interactions, enforce authority boundaries, and support secure operations at scale.
Early adopters are already using BAND to develop multi-agent systems across software development, enterprise automation, and advanced research and development use cases. The company is positioning itself as foundational infrastructure for what it describes as an emerging “internet of agents,” where autonomous systems collaborate across organizations and environments in real time.
KEY QUOTES
“We’re entering the agentic economy, where millions of agents will need to collaborate across companies, platforms, and environments. The challenge isn’t only building more agents, but getting them to work together in real time. BAND is building the infrastructure that makes that communication and interaction seamless, so agents can operate as part of a production-ready system, not isolated tools. This isn’t a nice-to-have, this is mission critical for the success of agent deployment in the enterprise.”
Arick Goomanovsky, CEO And Co-Founder, BAND
“Multi-agent systems are quickly becoming the foundation of modern software. Without a reliable and efficient way for agents to communicate, their potential is limited. BAND is building the missing layer that makes large-scale agent collaboration practical in all environments, in the enterprise and beyond.”
Tim Guleri, Managing Director, Sierra Ventures
