Fixie.ai
FundedReal-time, speech-native voice AI for natural human-like conversations
About Fixie.ai
Fixie.ai, through its Ultravox platform, delivers a unified real-time voice AI infrastructure designed to enable fast, natural, and scalable conversational experiences. Unlike traditional voice AI systems that convert speech to text before processing, Ultravox uses speech-native models to preserve paralinguistic cues such as tone and cadence, reducing latency and enhancing conversational fluidity. This approach addresses the common issues of slow and robotic voice agents by managing the entire inference stack and infrastructure internally, ensuring low latency and high performance.
The platform targets enterprises seeking to build sophisticated voice AI agents capable of real-time interaction across web and mobile environments. It offers developer-friendly REST APIs, SDKs, and built-in telephony integrations to facilitate seamless deployment and scaling of voice applications. Pricing options include a free tier for experimentation, a pro subscription for scaling companies, and custom enterprise plans for large-scale deployments. Fixie.ai emphasizes open science by sharing research and models openly, while maintaining a proprietary product offering tailored for enterprise use.
