ÆTHR introduces the trust layer for automotive inventory data

ÆTHR catches inventory data errors before they spread to websites, ads and marketplaces, so every system shows the same vehicle.

ÆTHR today announced its arrival in the automotive industry as the trust layer for automotive inventory data. ÆTHR catches errors in vehicle records before they spread to dealer websites, ad platforms, marketplaces and AI tools, so every system shows the same vehicle.

ÆTHR arrives already built, tested and proven. It runs in more than 100 live dealer environments and works with ad agencies and technology companies.

A single vehicle passes through many systems on its way to a shopper. The record starts in a dealer management system or inventory tool, then moves to the dealer's website, listing sites, ad catalogs and OEM programs. Each system formats and updates the record its own way. The same truck can show one price on a listing site, another in an ad and a third on the dealer's website. Dealers, agencies and OEMs often can't tell which version is right, or whether a change reached every system.

ÆTHR works between inventory sources and everything downstream, in four stages:

  • Validate: checks each record against OEM build and incentive data and every other source describing the same vehicle, and catches conflicts before they spread.
  • Standardize: turns every source into one consistent record, then hands it to each receiving system in the format that system expects.
  • Enrich: fills gaps in thin records with real vehicle data, brand-compliant vehicle descriptions, imaging, and incentive and rebate information.
  • Stream: sends each change to connected systems through one open API.

Then Prism checks the work. Part of ÆTHR, Prism looks at what is actually live on the dealer's website and sends corrections back when it doesn't match.

"Every system that touches a vehicle record is another chance for it to drift. Dealers, agencies and OEMs shouldn't have to guess which version of a vehicle is right. ÆTHR gives them one they can trust wherever it goes," said Michael Cirillo, co-founder and CEO of ÆTHR.

ÆTHR runs underneath the systems teams already use. Dealers keep their dealer management system, inventory tools and website provider.

Each group that depends on inventory data gets something different:

  • Dealers and dealer groups see fewer conflicts across the systems that represent their inventory.
  • Agencies get complete, accurate data behind every campaign.
  • Technology partners build on standardized, verified inventory through one open API.
  • OEMs set one inventory standard for their dealer network and trust it everywhere.

ÆTHR is available now at theaethr.ai. Teams can start a free trial with no credit card required. To learn more, read what a trust layer for automotive inventory data does or who built ÆTHR and why.

ABOUT ÆTHR

ÆTHR is the trust layer for automotive inventory data. For years, vehicle data has been split across disconnected systems, and every platform downstream inherits a bigger version of the same problem. ÆTHR validates, standardizes, enriches and streams inventory data from any source, so dealers, OEMs, agencies and technology partners all work from the same accurate vehicle record.
