Our Values

At Eloquent AI, we believe that true power lies in control, accuracy, and trustworthiness. AI must be precise, reliable, and aligned with human needs, especially in high-stakes applications where accuracy is non-negotiable. We build AI systems that businesses and individuals can depend on—solutions that consistently deliver the right response at the right time. Our mission is to harness AI to serve humanity, ensuring that it remains a tool for empowerment rather than a force beyond human control.

Customer-Centric Innovation

At Eloquent AI, we drive cutting-edge developments to tackle the real-world challenges enterprises face—delivering AI solutions that are not only innovative but also practical, scalable, and impactful. We prioritize simple, effective solutions over unnecessary complexity, valuing empiricism and pragmatism in everything we do. By continuously refining our technology based on real customer needs, we ensure that AI serves businesses in a tangible, results-driven way.

Measure, Learn, Improve

If you can’t measure it, you can’t improve it. Data-driven decision-making is central to Eloquent AI. We continuously evaluate performance, gather insights, and iterate. Our agent architecture and LLM models evolve through rigorous evaluations, ensuring they remain reliable, adaptable, and effective across research, engineering, and customer applications.

Own the Outcome

Eloquent AI fosters a culture of ownership, action, and perseverance. We empower our people to take initiative, embrace responsibility, and drive meaningful impact. In a fast-moving field, our team acts decisively, adapts swiftly, and pushes forward to achieve our mission.

Multi-Disciplinary Collaboration

Collaboration is the foundation of our success. AI is a multidisciplinary field, and the best solutions emerge when experts across domains come together to share knowledge and insights. At Eloquent AI, we foster a culture of open dialogue, cross-functional teamwork, and collective problem‑solving.

Department

At Eloquent AI, we’re building the next generation of AI Operators—multimodal, autonomous systems that execute complex workflows across fragmented tools with human-level precision. Our technology goes far beyond chat : it sees, reads, clicks, types, and makes decisions—transforming how work gets done in regulated, high-stakes environments.

We’re already powering some of the world’s leading financial institutions and insurers, fundamentally changing how millions of people manage their finances every day. From automating compliance reviews to handling customer operations, our Operators are quietly replacing repetitive, manual tasks with intelligent, end‑to‑end execution.

Headquartered in San Francisco with a global footprint, Eloquent AI is a fast-growing company backed by top-tier investors. Join us to work alongside world-class talent in AI, engineering, and product as we redefine the future of financial services.
