One belief: communication is where dealership profit is won.

Dealerships don't lose customers because demand dried up. They lose them because communication breaks down. Calls go unanswered, messages pile up, and the problem surfaces after the customer is already gone.

We watched this play out the same way across hundreds of rooftops, so we built Numa to fix it. The team behind it carries 150 years of dealership experience and 50 ML engineers, the same group that grew Location Labs to a $220M exit.

Core Values

The values we hold ourselves to

Drivers, not passengers

We're self-motivated, take initiative, and go beyond the call of duty. We take ownership, roll up our sleeves, and dive in, even when things are ambiguous.

Arete

The Greek word for excellence. We believe in being 1% better every day. We approach challenges with a growth mindset and reflect on our work to identify how to do things better next time.

Infectiously positive

We bring positivity to ourselves, our colleagues, and our customers. We find the upside in difficult situations and focus on cheering on the people around us.

Antifragile

Things won't always go right. We anticipate it, have a plan, and carry on in the face of adversity. We don't let challenges or anxiety get in the way of forward momentum.

Win as a Phalanx

In ancient history, soldiers in a Phalanx carried shields not for their own protection, but for the person next to them. We are the ultimate team player. Humble attitude. Focused on helping teammates above ourselves.

Customer success is everyone's business

We obsess over how our customers are doing with Numa. We're continuously focused on how to bring them a better experience and empower them to achieve their goals as fast and simply as possible.
