Purple vs Zenreach
Purple is a global guest, staff and multi-tenant WiFi platform built for enterprises and venues, pairing captive portal onboarding with footfall and dwell analytics, marketing automation and enterprise WiFi security. Zenreach, now operating as Adentro, is a US-focused WiFi marketing and attribution platform whose signature is Walk-Through Attribution, tying digital ad activity to in-store visits. The two overlap on guest WiFi data capture, but Purple is the broader infrastructure-and-analytics platform while Zenreach is specialised around US retail and restaurant marketing measurement.

When Purple is the right call
Purple wins when you need WiFi as infrastructure as well as marketing: guest, staff and multi-tenant networks managed together, footfall and dwell analytics across many sites, and enterprise-grade security and compliance. If you operate internationally, want published pricing and a self-serve calculator, or need a free entry tier to start, Purple is the stronger fit - and it backs that breadth with outcomes like a 57x return at Harrods across 80,000+ venues. It also suits organisations that span retail, hospitality, transport, healthcare and large venues rather than a single vertical.
When Zenreach is the right call
Zenreach (Adentro) is a strong choice for US brick-and-mortar retailers, restaurants and entertainment venues whose main question is whether advertising actually brought people through the door. Its Walk-Through Attribution is a well-known, purpose-built metric for connecting digital ad spend to physical visits, and its large US consumer-profile database supports custom-audience advertising. For a US single-market business focused on marketing measurement and behaviour-triggered email, Zenreach fits that job directly.
