About

The codes were never the hard part.

Any $20 reader will tell you a cylinder is misfiring. Knowing which of the six things that cause it is happening on this car, today, has always lived in one person's head. That person is getting harder to hire.

Every one of them is a real fault. One of them is the job.
Why we built it

Diagnosis is a judgment problem wearing a data costume.

The trade can’t hire that judgment

Every shop has one: the person you walk a hard car over to. That judgment gets built over decades of seeing the same faults repeat, which is exactly why you cannot post a listing for it. The trade has been losing that depth faster than it builds it for twenty years.

One of our founders has spent thirty years being that person. AceDx started as an argument between the two of us about whether the judgment could be written down.

The tools got better at reading, not thinking

Scan tools became extraordinary at pulling data off a vehicle. What none of them do is the thing the veteran does in four seconds: look at all of it at once and say what’s actually wrong. That gap is where the comebacks live.

AceDx is an attempt at that second part, and only that part. It doesn’t turn a wrench and it doesn’t know your customer. It reads the car and commits to a call, with the evidence attached, the way the sharpest person in the shop would.

What we believe

Six rules the tool has to obey.

Every one of them takes something away. What is left at the bottom is the only thing the tool is allowed to put in front of a tech.

What is left is the only thing it is allowed to say.
Each rule forbids a kind of sentence. The bar is what the tool is still allowed to say after it applies. Specimens are illustrative of the voice, not screenshots.
Who we are

Two brothers who took opposite roads.

Israel spent thirty years in the bay. Jerry spent twenty-five building software companies. The careers diverged early and stayed that way. AceDx is the first thing either of them found that genuinely needed both.

That is also the argument the product makes: diagnostic judgment and software have to sit in the same room, and neither one gets to overrule the other. It is easier to hold that line when the other person is your brother and will say so plainly.

Israel McEnry

CEO & Co-founder · 30 years in the bay

ASE certified for three decades, and most of that career spent either working shops or running them. Israel has been on both ends of the problem AceDx exists to solve. He has been the tech holding the scan tool on a car that will not give up its answer, and the owner watching a comeback eat a bay he had already sold.

He is the reason the tool commits to a call instead of listing possibilities. Thirty years of diagnostic judgment is the thing the product is trying to be a second opinion from, and it is the standard every verdict gets held to before it ships. When a verdict does not read the way a foreman would say it, Israel is the one who sends it back.

Jerry Soto

CPTO & Co-founder · 25 years building software companies

Founder of PeakCommerce, Kaana, and BaldPeak, acquired by Simplus and then Infosys. Twenty-five years of building systems in the AI and lead-to-revenue space, and the discipline of turning messy real-world signals into a decision somebody can act on.

That is the same problem in a different trade. A vehicle throwing five codes and a customer complaint is a data problem right up until the moment someone has to commit to a repair, and the commitment is the part that matters. His job here is to make the software worthy of his brother’s judgment rather than the other way round.

Where we actually are

Pre-pilot, and saying so.

AceDx works today. It reads vehicles, makes calls, cites its evidence, clears codes, and confirms on retest. What it has not done yet is prove itself across a season of live repair orders in shops that didn’t build it.

That’s what this fall is for. Until it’s done, this site will keep being conspicuously short on numbers, and we’d ask you to treat any diagnostic product that isn’t equally short on them with some suspicion.

Be one of the shops that decides what this becomes.

The pilot runs this fall, free, on the tools you already own. The shops in it have more say in the product than anyone who buys it later will.
