Quack was founded by Nadav Kemper and Aviram Roisman and is based in Israel, emerging as one of a new wave of agentic AI startups rethinking customer support from the ground up. The founders' insight is that traditional support is fundamentally reactive: a customer hits a problem, opens a ticket, and waits. Quack inverts that model by building proactive AI agents designed to spot emerging customer issues and resolve them before they turn into escalations, reframing customer support as a holistic operating system rather than a ticket queue.
The platform's core is a system for training and managing a network of AI agents that collectively own the customer experience. Rather than a single chatbot answering questions, Quack orchestrates multiple specialized agents that can identify problems, take resolving actions and coordinate across the support lifecycle. This proactive, multi-agent approach is meant to reduce both ticket volume and the friction customers experience, improving satisfaction while lowering operating cost.
Quack positions itself as a one-stop customer support platform for high-growth and global brands. Early customers reportedly include Artlist, Yotpo, WalkMe and Hologram, indicating traction with software and consumer-technology companies that value proactive, automated CX. Following its funding the company also brought on Doron Pryluk as Chief Operating Officer to scale operations and go-to-market, signaling an emphasis on US expansion.
In September 2025 Quack announced a $7 million seed round led by Hanaco Ventures and Storytime Capital, with participation from Fusion VC, Savyon Ventures, Seed IL and several private investors, including WalkMe CEO Dan Adika. The capital is earmarked for US go-to-market and product development. With its proactive, agentic premise and notable early backers, Quack targets brands that want to get ahead of customer problems instead of merely reacting to them.
