Guest WiFi that measures more than ad attribution
Adentro turns guest WiFi into a US marketing and ad-attribution tool. Purple captures the same first-party data - with a free plan to start - plus footfall and dwell analytics, staff and multi-tenant WiFi, and the scale to run a thousand sites on one platform. Better guest WiFi whether you run one venue or many.
- First-party data, footfall and dwell - beyond walk-through rates
- Works in the US and 90+ countries on one platform
- No hardware swap - runs on the access points you own
- Free Connect tier to start, upgrade when it pays for itself

One tap to connect, one platform to act on it
A guest taps Google, Apple or email on your branded splash page and becomes a known, consented profile. From that same sign-in, Purple builds visit history, footfall and dwell analytics you can act on - not just an attribution number for your ad spend.
- Consented first-party profiles from every sign-in
- Visit history, footfall and dwell in one dashboard
- Branded splash pages with no engineering work

Attribution tells you ads worked. Purple tells you what to do next
Knowing an ad drove a visit is useful; knowing who came back, how long they stayed and which site they chose is what changes decisions. Purple turns every WiFi sign-in into that intelligence, starting free with Connect and growing through Capture and Engage as your estate does. Hardware is covered too - add the plug-and-play £69 Purple Hub if you need it.
Frequently asked
Does Purple do ad attribution like Adentro?
Purple focuses on what happens inside the venue: consented first-party profiles, footfall, dwell and repeat-visit analytics, plus WiFi-triggered marketing. If your goal is proving and repeating in-store visits, the same sign-in data drives both jobs.
Can Purple run venues outside the US?
Yes - Purple operates across 90+ countries with GDPR and CCPA compliance built in, so one platform covers a US chain and its international sites. Adentro’s own marketing focuses on US in-store attribution.
What does switching from Adentro involve?
No hardware swap. Purple deploys as a cloud overlay on Cisco Meraki, HPE Aruba, Ruckus, Juniper Mist or Ubiquiti UniFi access points - or the £69 plug-and-play Purple Hub - and the free Connect tier means you can trial it alongside your current setup.
