We turn conversations into insight, patterns, and economic signal.

The infrastructure is table stakes. The alpha is in the conversation.

The Conversational AI Platform

Everything you need to build, deploy, and observe conversational AI agents.

Real-Time Infrastructure

Low-latency speech and text streaming built on WebRTC, optimized for natural turn-taking. Handle thousands of concurrent conversations with sub-second latency.

Context Engineering

Transform raw models into usable conversational agents. Morph LLMs into personas, enrich with structured context, and task them with goal-driven conversations.

Built-In Observability

Every conversation organized, indexed, and searchable from day one. No bolting on analytics later—visibility is the foundation, not an afterthought.

Never Split the Difference

Don't Compromise

Infra

Models

Access to state-of-the-art LLMs through clean, documented APIs. Pay per token, scale infinitely.

Building Blocks

Speech-to-text, text-to-speech, and streaming infrastructure. The primitives you need.

Frameworks

Agent orchestration, tool calling, and memory abstractions. A starting point for your product.

Alpha

Built-in Observability

Every conversation indexed from day one. Built on real-time infrastructure that never sacrifices visibility.

Conversational Pricing

Understand cost at the conversation level. Know which interactions deliver value per dollar. Optimize economics without sacrificing experience.

Conversation Alpha

Extract insight from dialogue itself. Backed by infrastructure that turns messy conversation into data.

Differentiated by Design

We're product-driven, not model-driven. LLMs are commodities—what matters is what you build with them.

Unlike platforms that profit when you burn compute, we're incentivized when you ship products. Our business model aligns with your success, not your cloud bill.

We built Lucile so you can focus on experience, outcomes, and economics—not infrastructure battles.

01
Conversational Alpha
While others stop at infrastructure pipes, we extract insight from conversation itself. Ask questions across thousands of interactions, surface patterns semantically, and move beyond anecdotes to grounded understanding.
02
Cross-Vendor Memory
Model vendors lock you in through memory. We abstract away the vendor layer, persisting rich conversational memory across multiple providers. Switch models without losing context.
03
Conversational Pricing
Understand cost at the conversation level, not just the vendor bill. Know which interactions deliver value per dollar. Optimize for economics without sacrificing experience.
