Ex-Sygnia and Ermetic founder raises $17 million Seed round to build the ‘WhatsApp for AI agents’
Band aims to solve the growing challenge of coordination and communication between AI agents inside enterprises.
Band, a startup developing a communication and collaboration platform for AI agents, has raised $17 million in a Seed round led by Sierra Ventures, Hetz Ventures and Team8.
Band was founded in mid-2025 by Arick Goomanovsky, CEO, and Vlad Luzin, CTO. Goomanovsky, a graduate of Unit 8200, is a serial entrepreneur with two successful exits. He co-founded Sygnia, which was sold to Temasek for $250 million, and later co-founded Ermetic, which was acquired by Tenable for about $300 million. He then served for nearly two years as VP of Product Innovation at Tenable.
Luzin is a graduate of the The Directorate of Defense, Research and Development at the Ministry of Defense (DDR&D) and has more than two decades of experience in development, product, and project management at startups and large technology companies, including Verint, CME Group and Samsung Global. He was an early pioneer of multi-agent systems and led Samsung’s multi-agent systems team under the CTO in the early 2000s.
In a conversation with Calcalist, Goomanovsky said: “I envisioned the company after we sold Sygnia and founded Ermetic. We believed in an agent-based economy, where machines would participate in economic processes alongside humans. The LLM revolution is making this possible, and agents are now entering organizations. We are building the ‘WhatsApp of agents’, a secure, real-time, two-way communication layer. For an agent economy to function, agents need the ability to communicate with each other and with humans. Until now, there were humans and traditional software systems; now a new entity has emerged - the AI agent - and it requires similar communication capabilities.”
“The market initially focused on building large, general-purpose agents,” he added. “But that approach doesn’t work well due to limitations in LLM context. The emerging architecture is multi-agent: many smaller, specialized agents working together. For that to succeed, they must be able to communicate effectively. We expect to raise a Series A round within the next one or two quarters. We already have initial revenues and are working with around ten partners.”
Band is developing an organizational infrastructure platform for managing and coordinating AI agents across various domains. The platform enables real-time collaboration between agents, other AI systems, and humans, both within internal enterprise systems and across SaaS platforms and external partners. It includes a control center that enforces organizational policies, defines permissions, and ensures transparency across systems.
As organizations begin deploying dozens or even hundreds of AI agents across development, security, and operations workflows, coordination is emerging as a major bottleneck. By the end of the year, around 40% of enterprise applications are expected to incorporate AI. However, forecasts suggest that roughly half of agent deployments may fail due to insufficient runtime governance and a lack of interoperability between systems. Many organizations still rely on manual processes to transfer context between agents, creating fragile coordination mechanisms that are not designed for large-scale automation.
