How we built an API-first engine for real performance
Fluents is powered by its own voice infrastructure - not a wrapper, not a reseller. We built our engine from the ground up to handle real-world calling at scale, with full control over latency, accuracy, and customization. Unlike competitors, we don’t rely on someone else’s black-box stack. Every interaction is processed through systems we’ve designed to be transparent, extensible, and optimized for actual business use.
Our API exposes that same core infrastructure to you. From outbound campaigns and lead follow-up to AI reception flows and web voice widgets, you can control it all - programmatically. Assign numbers, launch calls, update scripts, track performance, trigger workflows, and sync with your CRM or data layer, all through clean, well-documented endpoints.
We believe the best infrastructure fades into the background. That’s why our stack is built for reliability, but also adaptability. Fluents runs on a distributed, cloud-native architecture with services written in Golang and TypeScript, real-time audio processing pipelines, and tight integration into LLM-based decision layers. The result? You get an API that feels simple, but moves with enterprise-grade precision.
Whether you're building a new product, integrating with an internal tool, or just want deeper control over your AI callers - this is the platform that was built to handle it all, from scratch.
