We are building a foundation model for the car, because we think that is what the automotive stack becomes next.

Arenn.ai

Arenn.ai is an automotive AI research company founded in September 2025 in Santa Clara, California. We build AREN, a 3-billion-parameter multimodal model trained from the ground up on driving data, together with the perception, planning, and in-cabin systems that run on top of it.

How we work

We are a small team. We prefer one good measurement to ten claims. Research notes ship when they are ready, not to a marketing cadence. Everything we publish is something the engineers on the team would be comfortable defending in a technical review.

We hire slowly and in person. The work happens together, in Santa Clara, because the parts of this problem that matter — safety integration, sensor timing, deployment engineering — are discussed at whiteboards, not in calendar invites.

We do not publish partner logos we have not earned, benchmarks we have not measured, or certifications we do not hold. The model card is the shortest honest reading of what AREN is today.
