Audience
Developers and product teams shipping address-validation, geocoding, or postal-data features into their own products. Primary buyers: e-commerce platforms (checkout validation), CRM/RevOps admins (lead routing and territory mapping), store-locator product teams (service-area coverage), real-estate and market-research analysts (ZIP-level demographics), and logistics teams (distance and addressing across US + Canada). Self-service freemium pricing means individual developers can evaluate and ship without engaging a sales team.
