What Plus44 Holdings does

Plus44 Holdings Ltd (d/b/a Sliide) is a London-headquartered mobile technology company founded in 2013 that operates a B2B mobile experience platform targeting mobile carriers and OEMs. The platform integrates deeply into the Android OS, enabling operators and device manufacturers to manage, measure, and monetize the on-device experience without writing code. The product portfolio is built around three modules: the Experience Suite (configurable lockscreen, home screen, onboarding, native widgets, and a white-label News app in 130 languages), Propel (configuration, analytics, and retention tooling through robust APIs), and the Loyalty Suite (cashback rewards currently powered by Cardlytics across 10,000+ retailers). Underlying personalisation is delivered via the proprietary Accessware technology layer.

The company generates revenue through a mix of on-device content advertising, transaction-fee economics from the loyalty/rewards program, platform licensing of Accessware and the Sliide suite to carriers and OEMs, and data/analytics services. Pricing is not publicly disclosed, but the model is anchored on B2B contracts with carriers and OEMs and pre-installed, factory-integrated device distribution. The customer base spans large enterprise carriers (T-Mobile, Verizon, Tracfone, Assurance Wireless, Cricket Wireless, I Wireless, PWG) and OEMs (Motorola, Alcatel, BLU, Wiko, Nuu, SKY Devices, UMX, Hot Pepper), with reported reach of tens of millions of users per month. The company also serves app developers as a secondary segment, offering new device real estate and incremental revenue.

Plus44 Holdings is a private limited company registered in England and Wales (company number 08751708), with a London operational headquarters and a US toll-free presence. It is bootstrapped with no disclosed funding rounds or institutional investors, and is founder-led by CEO Corbyn Munnik (Forbes 30 Under 30). GTM is concentrated on enterprise field sales to carrier and OEM procurement, supplemented by participation in industry events such as Mobile World Congress and partnerships with industry bodies like IAB UK.

Direct peers

• Buzzvil: Buzzvil runs a lockscreen advertising and rewards platform integrated with carriers and OEMs across Asia, with the same on-device monetization thesis as Sliide's Loyalty Suite and Experience Suite.
• Digital Turbine: Digital Turbine delivers a device-embedded platform (Ignite) that enables carriers and OEMs to distribute and monetize apps and media on Android devices. It is the most direct comparable to Sliide, addressing the same MNOs and OEMs with pre-installed content, app discovery and monetization tooling.
• Glance (InMobi): Glance operates a lockscreen content and commerce platform pre-installed on Android smartphones via carrier and OEM partnerships, directly overlapping with Sliide's Experience Suite and Headlines products in the device-level content real estate.

Others

• Chartboost: Chartboost is a mobile ad network and programmatic monetization platform that appears in Sliide's partner ecosystem; it is an ecosystem enabler rather than a direct competitor to Sliide's device-experience platform.
• Cardlytics: Cardlytics powers Sliide's cashback rewards program and is also a strategic partner; it is adjacent rather than competitive, operating card-linked offer infrastructure for banks and merchants that Sliide channels into the on-device wallet experience.

Broad incumbents

• IronSource (Unity): IronSource, now part of Unity, provides app monetization, mediation and ad-tech infrastructure for mobile developers and OEMs at much larger scale. It overlaps with Sliide's ad monetization layer and OEM-level integration story, though it is not carrier-focused.
• AppLovin: AppLovin's AXON and SparkLabs stack power mobile app monetization and user acquisition across the ecosystem, including OEM and device-level channels, positioning it as a broader incumbent in the same mobile-monetization category as Sliide.
• Opera (Opera Mini / Ads): Opera pre-installs mobile browsers and content portals on low-cost Android handsets globally and monetizes through search, ads and content deals, overlapping with Sliide's lockscreen/home-screen content and OEM distribution model.

Emerging players

• Gimbal: Gimbal provides mobile engagement, location and messaging SDKs for carriers and brands, comparable to Sliide's subscriber analytics and in-device messaging layers though delivered through an SDK rather than OS-level integration.
• Swrve: Swrve provides mobile engagement, personalization and in-app messaging infrastructure for enterprises, with overlap to Sliide's Propel in-device messaging and analytics capabilities, though Swrve is app-centric rather than OS-embedded.
