About Us

As used EV and hybrid vehicle buyers ourselves, we know how difficult it is to assess a vehicle's battery health. We decided to build it and share it with the world.


Our team has over 20 years of experience building diagnostic and vehicle data tools for the automotive industry - from hardware design and firmware development to ECU reverse engineering and manufacturing at scale. We have worked with OEMs, auctions, and franchised and independent dealerships, and bought our share of EV and hybrid vehicles along the way.



Transportation is largest piece of your personal carbon footprint (more than your home, food, or the goods and services you purchase).

To reduce your impact, walk, bike, use public transportation, and use ride sharing. However, if you need a car, here are your options, from most to least sustainable

1) Buy a used EV or hybrid vehicle
2) Buy a new EV or hybrid vehicle
3) Buy a used ICE vehicle
4) Buy a new ICE vehicle

Our goal is to help you buy reliable and well running used EV and hybrid vehicles to help you meet your own personal sustainability goals.

Reduce, Reuse, Recycle – it’s a mantra from Kindergarten, but it’s not just for the classroom.
