OnlyEV

Nationwide EV marketplace with AI-driven dealer tools.

OnlyEV cover

Context

The problem.

Generic used-car marketplaces treat an EV like any other car — same filters, same comparisons, same search ranking. EV shoppers actually need range, tax credit eligibility, charging speed, and battery health front and centre. OnlyEV is the marketplace built for the way an EV shopper actually shops.

Role

What I owned.

  • Built the marketplace search and filter surface around EV-specific attributes.
  • Wired the listing pipeline that ingests inventory from partner dealerships.
  • Integrated GPT-driven search to handle natural-language shopper queries.
  • Worked the dealer-side tooling for inventory upload and listing management.

Approach

How it came together.

EV-native filters

Range, tax credit, drivetrain, max charging speed — first-class filter primitives, not an afterthought folded into a generic listings schema. Searching "under $25k, 300+ miles range, AWD" returns the right cars on the first query.

AI-powered search distribution

Natural-language queries route through a GPT layer that translates shopper intent into structured filters. The dealer never has to guess which keywords to put in their listing for the buyer to find them.

Trust as a product feature

Listings come from verified dealers, not anonymous sellers. The marketplace is built around the trust posture EV shoppers actually want — a multi-thousand-dollar tax credit doesn't survive a sketchy private-party transaction.

Outcome

Where it stands.

  • 3,500+ active EV listings across 48 states.
  • 100+ verified dealer partners on the platform.
  • EV-specific search and filters live across web and AI surfaces.
