SMBs locked out of modern marketing infrastructure
Cafés, bars and small restaurants have plenty of guest traffic but no practical way to capture it, segment it, or re-engage it. Enterprise MarTech stacks are far out of reach in cost and complexity.
No first-party customer data despite hundreds of daily walk-ins
Existing Wi-Fi hardware vendors do not provide marketing tooling
Paid social inflation makes return-visit acquisition harder every quarter
Owner-operators have no time or budget for enterprise MarTech
Plug-in MarTech that lives on the existing Wi-Fi
NULLSPOT installs on the venue's existing router, replacing the generic Wi-Fi splash page with a branded portal that collects opt-in contact data, segments visitors, and triggers re-engagement automatically.
Branded captive portal
Per-venue look-and-feel, multilingual, configurable in minutes - no developer required.
Compliant lead capture
GDPR-aligned opt-in flows that build the venue's own first-party audience list.
Visitor segmentation
First-time vs. returning, weekday vs. weekend, time-of-day cohorts - segmented automatically.
Marketing automation
Trigger email or SMS campaigns based on visit patterns to drive return visits.
AI network diagnostics
A live health score per access point, uptime tracking, peak-hours prediction and anomaly detection - so connectivity issues surface before guests complain.
How the SMB marketing offering changed
Wi-Fi reframed from a generic ISP splash into a first-party marketing channel hospitality SMBs can actually run.
Customer data
Before
Zero first-party data despite traffic
After
Opt-in lead capture on every visit
Audience becomes an owned asset, not a paid-social rental.
Wi-Fi experience
Before
Generic ISP splash page
After
Branded captive portal
Every connection becomes a brand touchpoint.
Marketing posture
Before
Paid social-only acquisition
After
Owned audience + automation
Return visits driven by data the venue owns.
Operator complexity
Before
Enterprise MarTech setup
After
Router-level plug-in for SMBs
Built for owner-operators, not marketing departments.
Network visibility
Before
No visibility into access-point health
After
AI health score, uptime and anomaly alerts per access point
Operators catch a failing access point before a guest complains about it.
A self-funded product now generating recurring SaaS revenue
Self-funded, revenue-generating
The product now sustains itself on subscription revenue rather than requiring continued internal funding
Recurring SaaS revenue
Monthly subscription revenue from live hospitality venues
50,000 – 199,999 €
Payback period
Ongoing - reinvested into feature growth rather than measured against a single payback date
Method
Internal product P&L tracking (subscription revenue vs. build and operating cost)
Confidence
High for qualitative traction; detailed commercial figures undisclosed
As NULLBIT's own product, detailed revenue and customer-count figures are commercially confidential.
NULLBIT-owned SaaS product, in market
NULLSPOT is NULLBIT's owned commercial product, live at nullspot.cloud and serving hospitality clients. Customer-level metrics are commercial-sensitive.

At onboarding
“Before NULLSPOT, our Wi-Fi was just... there. Now I actually know who's walking through my door twice a week, and I get an alert if an access point acts up before a single guest complains.”
