Adentro

The company operates a B2B SaaS and media platform that converts guest Wi‑Fi access into a first‑party data and attribution layer for physical locations. Its captive portals capture opted‑in visitor identities and visit timestamps, which flow into a cloud dashboard, audience builder and email tools to drive re‑engagement and measure in‑store outcomes of digital campaigns. This data and analytics underpin walk‑through attribution and network advertising offerings, creating value by helping physical businesses understand and influence foot traffic and tying ad spend to verified visits. For advertisers and agencies, the platform acts as an identity and visit graph that can be activated for offline outcome‑based media planning and measurement.

Adentro (formerly Zenreach) is a United States‑based private company providing Wi‑Fi‑based marketing and analytics software for brick‑and‑mortar businesses. Its platform uses guest Wi‑Fi portals to capture first‑party customer data and visit events, then links this to digital marketing activity for footfall measurement and walk‑through attribution.

The company sells cloud dashboards, audience and email tools, and network advertising capabilities to multi‑location retailers, restaurants, venues and other physical locations. Revenue comes primarily from per‑location SaaS subscriptions, with additional income from managed services, data‑driven advertising and attribution services for advertisers and media buyers targeting in‑store visits.
