About Anna Chen & Vivek Ramaswami — Madrona - Voice Is Going Vertical: How Verticalized Voice AI Is Becoming the Next Killer App - June 2025

A blog post by Anna Chen and Vivek Ramaswami of Madrona Ventures, published June 18, 2025, analyzing the rise of verticalized voice AI agents. The article argues that advances in LLMs and voice infrastructure have reached a tipping point, enabling domain-specific voice agents to transform industries such as home services, insurance, loan servicing, auto dealerships, healthcare, and finance. It highlights the importance of deep domain data, real-time interactions, and lowering infrastructure costs, while noting that over 80% of enterprise data remains in voice and that consumers still prefer phone-based customer service. Madrona points to investments like Deepgram and sees large winners emerging across the voice stack.
