Yellow.ai builds AI agents that automate customer service and employee support conversations across voice, chat, email and SMS. Agents are built in AI Agent Builder 2.0 from natural language prompts, answer from a Conversational Knowledge Base using agentic retrieval, and are tested with automated testing and an AI Copilot that previews, debugs and tunes their behaviour before release. An Analyze module mines conversations to improve agents and generate knowledge base articles, and Agent Assist supports human agents when conversations escalate. The current product family is Nexus, with Nexus VOX for voice agents (Yellow.ai claims 500+ languages) and Nexus EDGE, a desktop agent for employee experience that asks for human approval on every action.
The distinctive design choice is a multi-LLM architecture: Yellow.ai routes tasks across 15+ models and pitches this as avoiding lock-in to any single model vendor's pricing or capability. The other is breadth of deployment. Yellow.ai says it has 150+ prebuilt integrations, including Salesforce, Zendesk, Genesys, NICE, Freshdesk and HubSpot, and that its platform is trained on 16B+ conversations a year. Data is hosted in the US, EU, Singapore, India, Indonesia and UAE.
The company was founded in 2016 as Yellow Messenger by Raghu Ravinutala (CEO), Jaya Kishore Reddy (CPO) and Rashid Khan (CMO), rebranded to Yellow.ai in 2021 and raised a $78.15M Series C that year after a $4M Series A in 2019. It is headquartered in San Mateo, California, with offices in India, Singapore, Malaysia, the UAE and Indonesia, and says it is trusted by 650+ global brands. Named customers include Sony, Randstad USA (employee W2 requests answered in minutes rather than 4 to 24 hours), Waste Connections (after-hours voice AI that saved millions of dollars), VIPdesk (more than 70 percent of interactions automated within six weeks of launch), Lion Parcel, InteleTravel and the City of Cape Coral.
Pricing has a free tier with one AI agent and 500 chat sessions a month included, then $0.99 per resolution, and an Enterprise plan by quote that unlocks all 35+ channels and unlimited usage. Choose Yellow.ai if you are a large, multilingual or multi-region enterprise that wants one vendor for voice and chat automation across both customers and employees. Skip it if you mainly need a helpdesk with a bot attached; Yellow.ai is an automation layer that sits on top of your existing helpdesk or contact center rather than replacing it.
