What Lunio does
Lunio is an AI-powered ad traffic verification and protection platform that detects and blocks invalid traffic (IVT) and click fraud across paid digital advertising channels. Founded in 2016 and headquartered in Manchester, UK, the company serves performance marketers, digital agencies, lead generation businesses, e-commerce brands, and large enterprise advertisers running campaigns on Google Ads, Meta, Microsoft/Bing, TikTok, LinkedIn, and other major ad platforms. According to Lunio's own 2026 Global Invalid Traffic Report, over 8.5% of paid ad clicks are invalid on average, representing a substantial and persistent industry problem.
The core platform uses a multi-layered machine learning detection engine combining IP reputation analysis, device fingerprinting (hundreds of behavioral and technical signals), and behavioral analysis to identify invalid clicks in real time. ML models are updated daily using customer conversion data and the company claims a false positive rate below 1%. The platform integrates natively with nine or more ad platforms via API, supports account-level automatic IP blocking, and is architected around modular solutions covering Paid Search, Paid Social, Display, Performance Max, and Affiliate Fraud Prevention. Supporting tools include a free Click Fraud Calculator and the annual Global Invalid Traffic Report, which analyzed 2.7 billion paid ad clicks in its 2026 edition. The company holds SOC 2 Type 2, ISO 27001, TAG, and IAB certifications and is GDPR/CCPA-compliant through a cookieless architecture.
Lunio operates a subscription-based SaaS model with flat-fee pricing based on monthly monitored traffic volumes (not ad spend percentage), typically structured as 12-month annual contracts with a 90-day non-renewal notice. The go-to-market is primarily enterprise sales-led, with an inside sales team handling mid-market deals and a product-led free 14-day traffic audit serving as the self-serve entry point. The company has raised approximately £18.5M across multiple funding rounds since 2018, with Praetura Ventures, Fuel Ventures, and Smedvig Ventures as key institutional investors. Named enterprise customers include M&S, Hugo Boss, Sykes Cottages, LearnWorlds, DeVry University, Canto, Represent, and Sparkles.io.

Lunio competitors and assessment
Company assessmentDirect peers
- CHEQ: CHEQ is a direct competitor offering click fraud, ad verification, and lead validation across paid media channels. It targets the same performance marketer and enterprise buyer as Lunio with a comparable SaaS go-to-market.
- ClickCease: ClickCease is a direct competitor providing click fraud detection and IP blocking for Google Ads and Bing paid search advertisers. It overlaps closely with Lunio's paid search and paid social modules at typically SMB and mid-market price points.
- TrafficGuard: TrafficGuard offers ad fraud prevention and invalid traffic detection across paid search, paid social, and in-app. It serves similar performance marketing and agency buyers as Lunio with comparable cross-channel coverage.
- Pixalate: Pixalate provides IVT and ad fraud detection across connected TV, mobile, and digital advertising. It is a direct peer to Lunio in the IVT detection category, with deeper coverage of CTV and programmatic that Lunio does not yet address.
Broad incumbents
- HUMAN (White Ops): HUMAN is a larger, well-capitalised ad fraud and bot mitigation vendor. It competes with Lunio on invalid traffic detection but at greater scale and with broader cybersecurity adjacencies, positioning it as a broad incumbent rather than a specialist peer.
- DoubleVerify: DoubleVerify is a leading ad verification and IVT platform serving enterprise brands and agencies. It offers overlapping invalid traffic measurement alongside brand safety and viewability, making it a broad incumbent peer rather than a direct SMB-focused competitor.
- Integral Ad Science (IAS): IAS provides ad verification including IVT detection, brand safety, and viewability. It is a broad incumbent competitor overlapping with Lunio on the IVT detection use case but typically bundled with larger media-quality contracts.
Emerging players
- AppsFlyer: AppsFlyer is a mobile measurement and attribution platform with attribution fraud protection features. It overlaps with Lunio on the ad fraud prevention use case but is anchored in mobile app ecosystems rather than web paid media.
- Adjust: Adjust is a mobile attribution and fraud prevention suite. It shares Lunio's IVT and fraud-prevention ethos but targets mobile-first marketers rather than the web paid-search and paid-social buyer Lunio prioritises.
Others
- Singular: Singular is a marketing attribution and analytics platform with fraud prevention capabilities. It is thematically adjacent to Lunio — overlapping on ad fraud signals — but its core product is attribution and ROI analytics rather than dedicated IVT detection.
