Multi-Industry
Industry Coverage
LEX is designed for any asset class. The same lead message structure works across automotive, aviation, maritime, heavy equipment, real estate, technology, and general B2B procurement.
Design Principle
One Standard. Every Asset Class.
The core desiredProduct block is industry-agnostic. The assetClass enum selects the vertical, and optional industry-specific spec blocks (like evSpecifications or aviationSpecifications) carry additional detail without breaking implementations that don't support them.
Fleet and multi-unit orders are supported natively. The organisation buyer model enables company, fleet, government, and NGO procurement — with B2B financing structures including tender, framework agreements, ECA financing, and Device-as-a-Service.

Fleet & Organisation Buyer Model

- •Government and defence procurement
- •NGO and humanitarian organisation purchasing
- •Ride-sharing and logistics operator bulk orders
