Guest WiFi marketing for UK hospitality
Your guest WiFi is giving away free internet for nothing.
CaptiveFlow replaces the password on your chalkboard with a branded splash page. Every guest enters their email to get online. You get a marketing list that grows every day you're open.
500+ marketing opt-ins in the first month at our newest venue.

01 / How it works
From box to first email,
in five minutes flat.
No technicians, no cabling, no contract negotiations. We ship you a FlowBox, you plug it in, and your guests start tapping in their emails the next time they connect.
Step 01
We ship your FlowBox.
Pre-configured for your venue. Arrives ready to plug in, no assembly.
Step 02
Plug it in.
Power and ethernet for FlowBox Pro. Power only for FlowBox Solo. It connects itself.
Step 03
Brand the portal.
Logo, colours, welcome line. Your venue, not ours.
Step 04
Capture every email.
Guests connect, you get their email. Your list grows on its own.
Capture, recognise, and grow
your guest list. Automatically.
Capture emails through a branded portal, recognise returning guests, and send the marketing that turns first visits into regulars. One device, one dashboard, one monthly fee.

Branded portal in your colours.
Drop in your logo, set your accent colour, write your welcome line. Live in five minutes.
Recognise
Regulars skip the form.
Recognised devices auto-connect. You see who's a regular without anyone retyping their email.
Comply
GDPR done properly.
Marketing opt-in always unticked. Soft delete, audit trail, UK hosted. No extra paperwork.
Sync
Straight into Mailchimp.
Opted-in guests land in your audience automatically. Klaviyo and HubSpot on the way.
Hardware
FlowBox plugs in once.
Works alongside UniFi and Meraki, or stands alone for venues without a managed network.
Insight
See who's actually coming back.
Visit counts, peak hours, return rates. The numbers your accountant won't show you.
02 / Pick your hardware
Two FlowBoxes.
Whichever fits your venue.
FlowBox comes in two variants. Both run the same captive portal, capture the same data, and feed the same dashboard. The difference is whether you're starting fresh or working with what you've already got.
FlowBox Solo
All-in-one for venues without managed WiFi.
"Plug it in. Done."
FlowBox Solo is its own access point. It powers up, broadcasts a guest WiFi network, and runs the captive portal — no other equipment needed. Ideal for small pubs, cafés, pop-ups, and any venue running on basic ISP routers.
Good if you
- →Have no managed WiFi controller
- →Want a single device that does it all
- →Need under 30 concurrent guests
FlowBox Pro
Integrates with your existing managed network.
"Adds the marketing layer."
FlowBox Pro slots into your existing UniFi, Meraki, or other managed controller. Your access points keep doing what they do — Pro adds the captive portal, the email capture, and the dashboard on top. No rip and replace.
Good if you
- →Run UniFi, Meraki, or similar
- →Need unlimited concurrent guests
- →Operate multiple sites or larger venues
No setup fees.
No nasty surprises.
Hardware is included. Twelve-month minimum, billed monthly. Cancel after that whenever you like.
