AppsFlyer

AppsFlyer was founded in 2011 by Oren Kaniel and Reshef Mann. The company is headquartered in Herzliya, Israel, operating as a private entity. Its last publicized major funding round was a $210 million Series D in early 2020 led by General Atlantic, valuing the company at $2 billion, followed by a subsequent late-stage investment from Salesforce Ventures. AppsFlyer employs over 1,000 people globally. The core product is a SaaS platform providing mobile marketing attribution and analytics, enabling app developers and marketers to trace app installs and user engagement back to specific advertising campaigns. In late 2023, AppsFlyer expanded its capabilities by acquiring the analytics platform devtodev.

The primary product line revolves around mobile attribution. AppsFlyer provides software development kits (SDKs) and APIs that mobile apps embed to measure which ad networks or social channels drive user acquisition. This solves the problem of calculating return on ad spend (ROAS) across the fragmented mobile ecosystem. The buyers are primarily marketing teams, user acquisition (UA) managers, and product managers at mobile-first and gaming companies. AppsFlyer's technical foundation is built to handle massive scale; its engineering organization is notable within the Israeli tech ecosystem for its extensive use of Clojure and Go to process billions of mobile events daily.

The core offering is the Mobile Attribution and Analytics suite. Alongside this, AppsFlyer operates Protect360, a product designed to detect and block mobile ad fraud such as click injection and device farming. Another major product is OneLink, a deep-linking engine that routes users from web links directly to specific in-app pages. In response to ecosystem changes deprecating device-level identifiers (like IDFA), AppsFlyer launched Privacy Cloud and Data Clean Rooms, allowing brands and ad networks to collaborate on measurement and campaign optimization without exposing personally identifiable user data.

AppsFlyer competes directly with other mobile measurement partners (MMPs) such as Adjust (acquired by AppLovin), Branch Metrics, Kochava, and Singular. The business model is typically structured around conversion or usage volume pricing. The most significant structural headwind facing the company in recent years has been the platform-level privacy policy shifts from Apple (iOS 14.5+) and Google (Privacy Sandbox). These changes disrupted the traditional device-ID attribution model and forced the entire MMP category to pivot toward aggregated measurement frameworks like Apple's SKAdNetwork.

The company’s global headquarters and primary R&D center are located in Herzliya. The Israeli site houses hundreds of employees, encompassing the executive leadership, product management, and the vast majority of the engineering organization. Both founders are Israeli. Locally, the company typically hires backend engineers, data scientists, and infrastructure engineers experienced in high-throughput distributed systems, driven by the requirement to handle immense volumes of real-time data processing.
