Dealer group data onthe groups that own the rooftops
Parent-group rollups, rooftop rosters, headcount and decision-maker counts, provider mix, and combined inventory — in one feed. Stop pitching rooftop-by-rooftop and start landing group-wide deals.
Dealer Groups Data is self-serve in the portal, and the 20 credits from our $0.99 trial spend on it too — 5 credits per dealer group. Need a high-volume quote? Talk to us about enterprise pricing.

What you get
Built for OEM corporate, PE/M&A research, group-deal sales teams, and analysts who need parent-group structure on every metric.
Parent-group rollups
Combined inventory across every rooftop, member count, OEM franchises held across the portfolio, and average years in business — the whole group rolled up into one row. AutoNation, Lithia, Sonic, Group 1, plus thousands of regional groups most data brokers miss.
Employee & decision-maker counts
Total employees, total decision-makers, and HQ-only employee and decision-maker counts for every group — sized so you can prioritize by org scale. Join the Contacts product to reach named decision-makers (GMs, owners, CMOs).
Rooftop counts and OEM mix
Member rooftop count per group and the OEM franchises spanning the portfolio. Prioritize the groups whose footprint actually matches your ICP.
Rooftop roster
Every member dealership by name, plus website host keys and Hermes rooftop IDs — ready-made join keys back to the Dealers product for the full per-rooftop record.
Provider mix & tenure
Distinct website providers across the group, the top provider, and the full provider mix — plus average years in business. Spot groups mid-replatform or standardized on a stack you integrate with.
Who it's for
Anyone whose work cares about who actually owns the rooftops — sellers, buyers, researchers, and the OEMs and lenders who finance them.
OEM & corporate teams
Measure distribution by parent group, monitor consolidation in your franchise network, and prep for renewal conversations with the buyer, not the operator.
PE, M&A, and research
Track auto-retail consolidation as it happens. Parent-group rollups, combined inventory, provider mix, and member rosters — without the manual research.
Group-deal sales teams
Sell group-wide, not rooftop-by-rooftop. Pitch the corporate office, reach the group's HQ, and bundle pricing across the full footprint.
