Captain. AI agents for car dealerships.

I lead engineering at Captain. It answers customers in WhatsApp, chat and on the phone, in their language, and books the test drive into the dealership's calendar before a person has to step in.

Building with AI

Agents are my day job. Here is what I have learned shipping them.

I use LLMs in two ways: as the product we sell, and as the way we build it. Both taught me that the model is the easy part.

Agents in production
Captain talks to real customers in chat, WhatsApp and on the phone. Tools, memory, hand-off to a human and a score for every conversation.
Voice and telephony
Real-time speech, SIP and Asterisk, low-latency pipelines. A call with an agent has to feel like a call, not like a form.
Knowledge, not guesses
Curated knowledge bases, site sync and gap reports. The agent answers from facts, and tells you what it could not answer.
AI-native engineering
Rules, skills and MCP servers around GitLab and Notion. An agent picks up an issue, makes a plan, writes the code and opens a merge request across a multi-repo platform.
