Fixie.ai

Fixie.ai is focused on developing real-time artificial intelligence that can interact with people in a way that closely mimics natural human conversation. Their core product, Ultravox, is a model and technology stack designed to build and scale human-like voice AI agents. Unlike traditional AI chatbots that rely on text-based interactions, Fixie.ai aims to bring AI into the fast-paced, often messy world of spoken communication, where interruptions and overlapping speech are common.

The company believes that the true potential of large language models (LLMs) lies beyond the confines of text boxes. To unlock this potential, Fixie.ai is building multi-modal models capable of understanding and participating in real-time, voice-driven exchanges. This approach is intended to make AI more useful, productive, and accessible in everyday human interactions, moving closer to the vision of artificial general intelligence (AGI).

Fixie.ai has worked with hundreds of customers and partners to integrate LLMs into various workflows, learning firsthand about the challenges and opportunities of deploying AI in real-world scenarios. Their shift toward real-time, voice-focused applications reflects their commitment to pushing the boundaries of human-AI interaction. The company has raised $17 million from leading venture capital firms, underscoring investor confidence in their vision and technology.

Currently, Fixie.ai is working with select partners interested in real-time voice applications, and is transitioning away from its earlier chat-only services. Their team is actively hiring for roles in speech understanding, speech generation, foundational multimodal models, and full-duplex communication, signaling ongoing innovation at the intersection of AI and human communication.
