The story
United Rentals is the world’s largest equipment rental company, with around 26,000 employees. Their salespeople are always on the move, so we built “AI Max” — a voice assistant that lets them place complex orders by simply speaking.
Salespeople were juggling thousands of machines, customers and job sites — usually from a truck or a construction site, not a desk.
What we built for them
Talk, don’t type
Say what you need and the assistant drafts the order in your cart.
Works everywhere
One app on the web, iPhone and Android.
Learns your voice
A quick calibration helps it understand you, even on a noisy site.
Your customers at hand
Assigned customers and favourites are always one sentence away.
How we got there
Every project is different. Here’s how this one came together.
Started ambitious
We first built a fully custom team of AI helpers to prove the idea.
Then made it simpler
We moved to a ready-made AI platform from Amazon to move faster and keep it reliable.
Then made it faster
We reworked how it looks things up so answers come back quicker.
Listened to real users
Feedback from salespeople shaped the voice quality and accuracy round after round.
In their words
Showcased at the company’s annual management meeting
“Polar Stork undertook the ambitious challenge of developing an AI-driven voice conversational agent designed to revolutionize how Sales Representatives place reservations on behalf of customers. The resulting product is not only a testament to their innovation and expertise but has also garnered such acclaim that it will be prominently showcased at the company’s Annual Management Meeting — a true benchmark of its impact and excellence.”
