What Sentinel Software does
Sentinel Software Limited, trading as Sentinel, is a privately held UK hospitality technology company founded in 2008 and headquartered at 136 Old Shoreham Road, Brighton. The company builds a WiFi marketing and guest engagement platform targeted at hotels, resorts, and other hospitality venues, structured around the Guest WiFi Solution at its core, the WiFi Marketing Platform for guest engagement and CRM data capture, and add-on modules for gamification (notably digital scratch cards) and single sign-on across multi-property estates.
The platform's technical differentiators include self-managed splash pages, branded on-designs, reported opt-in rates above 80%, and integrations with hundreds of CRM and marketing systems, anchored by Salesforce, Airship, Bloomreach, Stampede, and ImpactData Talkbox. The company claims guest data flows into customer CRMs three times faster than baseline, positioning WiFi login as the first digital touchpoint for loyalty and remarketing.
Sentinel operates as a subscription SaaS business with annual billing and a transparent pricing posture (no metered usage, no freemium tier, no per-access-point counting). GTM combines a product-led self-service motion for onboarding with dedicated account management and free training for larger hospitality clients, supported by direct sales. Public disclosures are limited: the firm employs 1-10 people, has no disclosed funding, no named customers, no management team details, and no AI capabilities on record.
