The trust layer for automotive inventory data Every system should see the same vehicle.
ÆTHR checks, standardizes and enriches every inventory record. Then it streams the same trusted vehicle to every website, platform and AI agent that depends on it.
Same vehicle. Different data.
The vehicle stays the same as its information moves. Its data drifts.
OEM to DMS. DMS to inventory tool. Inventory tool to website, listing site and ad platform. Every handoff is a chance for a price to go stale, a photo to drop or a sold unit to stay live.
Nobody along the way checks the message. So the error travels with it.
Bad data used to cost a click. Now it can cost the answer.
A sold truck still shows as available. One vehicle has three prices. Ads keep paying for clicks on a unit you can't sell. A shopper who spots the mistake might still call. An AI agent won't. It moves on to a dealer whose data checks out.
More systems read your inventory. Some of them answer for the shopper.
Websites, marketplaces and ad platforms already depend on your data. AI assistants are the newest. They read every source they can reach and answer in seconds. If your data conflicts, they pick a dealer whose data doesn't.
The industry is adding locks. ÆTHR hands you the switchboard.
As AI changes how vehicles get found, access to dealer data becomes the prize. Expect more gates, more fees and more systems that hold your data on their terms.
ÆTHR is built the other way. Your inventory data stays yours. You decide which websites, platforms, partners and agents can read it. You can take it with you any time.
We didn't inherit a business that depends on closed data. So we built one that opens it, on your terms.
The trust layer for automotive inventory data.
ÆTHR sits between your inventory sources and everything that depends on them. It checks every record, fixes what's wrong and sends the same trusted vehicle everywhere it needs to go.
The trust layer for automotive inventory data.
ÆTHR sits between your inventory sources and everything that depends on them. It checks every record, fixes what's wrong and sends the same trusted vehicle everywhere it needs to go.
We named it ÆTHR, inspired by the ancient element believed to fill the space between everything. You won't see it working. You'll see what it holds together.
Four stages. Every vehicle. Every time.
Follow one vehicle through ÆTHR.
ÆTHR checks your DMS, IMS and website records against each other to find errors and conflicts before they reach anything downstream. Conflicting prices, wrong trims, missing photos, sold units still listed and more get flagged at the door.
Every DMS, inventory tool, feed and ad catalog wants vehicle data in its own format. ÆTHR maps your data into one consistent structure, then delivers it the way each downstream platform requires.
ÆTHR fills in what the record is missing: OEM build data, incentives and rebates, photos with background replacement, and a description written for that exact VIN to the OEM's brand standards.
Inventory isn't a static file. ÆTHR doesn't wait for feeds. Its proprietary streaming system sends accurate data to every connected system as it happens.
Then Prism checks the work.
Sending clean data is half the job. Prism watches what's actually live on the dealer website, on its own, separate from any feed. If what shoppers see doesn't match what ÆTHR sent, Prism flags it and pushes the fix back.
Keep your systems. Lose the inconsistencies.
ÆTHR works underneath what you already run. No new login for your team. No migration. No retraining. We connect to your sources and your data starts moving cleaner.

ÆTHR can send feeds. It also controls when they send, how they're set up and whether the data in them is right. Every record runs through four stages before it goes out: Validate, Standardize, Enrich and Stream.
Do I have to replace my DMS or inventory tool?+
No. ÆTHR runs underneath the systems you already use. You can be up and running in as little as 30 minutes. ÆTHR checks your DMS, inventory tool and website listings against each other and catches errors before they reach downstream systems. Every system gets the same accurate vehicle.
Who owns the data?+
You do, and you can take it with you. Connect your existing systems. ÆTHR finds the errors, then cleans, enriches and streams your data on its own.
Will this work with AI shopping assistants?+
Yes. This is where it gets fun. More AI agents read dealer websites every day, so accurate inventory data matters more than ever. ÆTHR gives them the same verified record your website, marketplaces and ad platforms get. You can also connect ÆTHR to the AI assistant you already use. Ask about your inventory and act on it in plain language.
What does it cost?+
Pricing depends on your setup. ÆTHR works for single-rooftop dealers, OEMs and everyone in between, so pricing fits how you use it. Start with a free trial. No credit card required.
