A car sits parked 95% of its life. Yet most insurers charge as if it's always moving - and price you on age, sex and ZIP code. Just flips the meter on. You pay for the miles you actually drive, and the rate moves with how you drive them.
It's a Tuesday. A nurse finishes a short commute, parks, and locks the car. Her phone - not a plug-in dongle, not a windshield gadget - has already logged the trip: distance, time of day, the smoothness of her stops. At the end of the month, her insurance bill reflects exactly that. A few miles. Careful braking. A small number.
This is Just in ordinary operation. The company sells auto insurance in Arizona and Nevada, runs out of Los Angeles, and treats your driving as the price - not a discount you have to argue for. Liability-only customers pay no monthly base fee at all. If the car never leaves the driveway, the bill is close to nothing.
The pitch is almost suspiciously simple, which is usually a sign the hard part is hidden somewhere in the engineering.
"Rates should reflect the choices people make - not immutable characteristics like age, sex or ZIP code."
- Just's founding principlePictured: a smartphone doing the job a clipboard and a demographic table used to do, only with fewer assumptions about your birthday.
Here is the uncomfortable math of legacy auto insurance: it leans on proxies. Your age. Your gender. Your marital status. The ZIP code printed on your license. These are convenient because they are easy to collect and easy to model. They are also, frequently, a poor description of how you actually behave at 7 a.m. on a wet on-ramp.
The result is a system where a careful low-mileage driver subsidizes a reckless one who happens to share a demographic box. You pay a flat premium whether you drive 4,000 miles a year or 24,000. The meter never moves, even when your car doesn't.
Two of Just's founders had lost people to traffic accidents. So the fairness question wasn't abstract. If safer driving genuinely reduces risk, why doesn't the price say so - immediately, every month, in dollars?
"A car spends most of its life parked. The premium, somehow, never naps."
- The tension Just was built aroundJust was founded in 2019 by Robert Smithson, a Cambridge philosophy graduate who had already built and sold companies - co-founding Genius Sports (sold for roughly $280M in 2018) and PythonAnywhere. Alongside him, Murray Macdonald brought two decades in technology and insurance as co-founder and COO. Finance came from a chartered-accountant-turned-CFO with an investment banking background.
Their bet was that telematics had finally gotten good enough to price risk on conduct instead of category. Phones could measure how, when and where someone drives. If you could capture that cleanly - and crucially, reprice it monthly - you could reward a safe driver fast enough that they'd actually feel it. Not at renewal. Not next year. This month.
It was, of course, a wager that customers would trade a little location data for a fairer bill. Skeptics noted that "a little location data" has a way of becoming a sentence. Just leaned on privacy-compliant collection and the argument that the trade was honest: your driving, for your price.

Open the app. Answer a few questions. A quote arrives in about 20 seconds. From there, Just behaves less like a policy and more like a utility meter: it tracks the miles you drive and prices them, with rates adjusted monthly based on your driving behavior. Pay weekly, bi-weekly or monthly - whatever fits the paycheck.
Coverage isn't a toy tier, either. Drivers can get minimum liability, full coverage (collision, comprehensive, glass and liability), and uninsured/underinsured motorist protection. The structure is the clever part: liability-only customers pay no monthly base fee and are billed per mile; full-coverage customers add a small daily charge. Drive less, pay less. Drive better, pay less again.
"The per-mile price a customer gets can change every month - to rapidly reward safe drivers with lower rates."

A startup timeline, like a road trip, is mostly the unglamorous middle - the funding announcements are just the gas stations.
Talk is cheap; loss ratios are not. The loss ratio - claims paid against premiums collected - is the number that tells you whether an insurer is pricing risk well. A lower number means you're selecting and pricing your drivers better. In 2020, Root's direct loss ratio sat around 82%. Just reported 65.8% year-to-date in 2021. Different years, same direction of argument: pricing on behavior was selecting safer drivers.
"Customers report saving roughly 40% versus their previous insurer - the kind of number that turns a meter into a habit."
- On Just's customer savings claimsQ2 2021 added 1,000+ new policies - about a tenfold jump year-over-year, with revenue up roughly 1,400%.
Safe drivers can reach up to 50% savings after 12 months - quoted around $580/yr in Arizona, $615/yr in Nevada.

The mission underneath the meter is plain: price insurance on the choices people make, reward safe driving fast enough to matter, and - because safer driving is the whole engine - nudge the roads toward fewer accidents. Fairness and safety aren't separate goals here; they're the same lever pulled from two ends.
The vision runs bigger than two states. The founders have talked about expanding across the United States and, eventually, worldwide. Whether a per-mile model can scale across 50 regulatory regimes is the open question every insurtech faces. Just's answer is to keep the unit of pricing - the mile - the same everywhere, and let the behavior do the talking.
"If safe driving lowers risk, the price should say so this month - not at some distant renewal."
- The Just thesis, in one lineReturn to that nurse. End of month, the app tallies a short commute and steady hands at the wheel. The bill is small - not because she argued for a discount, and not because an algorithm decided she fit a friendly demographic box, but because she drove a little and drove well. The meter simply agreed with reality.
That's the change Just is trying to make ordinary. An insurance bill that responds to you, monthly, in dollars you can feel. It competes with Root, Metromile, Nationwide's SmartMiles and Allstate's Milewise for the same idea, and it still has the hard work of scaling state by state ahead of it. But the underlying move is hard to un-see: once a price can track your behavior honestly, charging a flat premium for a parked car starts to look like a relic.
A car sits parked most of its life. With Just, for the first time, so does the bill.
