Company profile
researched Aug 2026Appstack is a measurement and attribution platform for mobile apps and games that run paid advertising. The company positions itself as infrastructure that lets app teams scale user acquisition without building their own measurement or attribution stack. Its documentation describes three core infrastructure services: ad links and redirection (tracking links that measure ad engagement and route users to the app store with low latency), an attribution service that matches users to the ads that drove them via the Appstack SDK, and signal engineering that enriches conversion events and forwards them to ad networks in real time.
The product set marketed on the company site covers mobile attribution with real-time, device-level data at the ad level; enriched signals such as "Trial qualified" events; ad-based user journeys in which onboarding screens and paywalls vary according to the ad that drove the install; and deep linking that gives creators individual trackable links with revenue-share payouts. Appstack frames these capabilities collectively as "enhanced app campaigns" (EACs), which it says unlock campaign types and inventories including Google search-to-app, TikTok search ads, YouTube Shorts and display, with granular control over placements and targeting. The company also cites end-to-end encryption of attribution data, custom attribution models, and coverage of all iOS devices.
Onboarding is invite-only: prospective customers request access, then create an organization, install the Appstack SDK, connect ad-network integrations, and launch a first enhanced app campaign. SDKs are listed for Swift, Kotlin, React Native, Flutter and Unity.
Business model
B2B SaaS sold directly to mobile app publishers on a self-serve and invite-gated basis, with an SDK-plus-integrations delivery model.
Tiered subscription pricing published on the company site: a free "Starter" tier covering up to 10,000 paid installs (one-time) with enhanced app campaigns and unlimited users and apps; a "Growth" tier at $299 per month plus $0.02 per paid install, billed monthly with geo-based pricing and priority support; and a custom-priced "Enterprise" tier on yearly commitments that adds dedicated Slack support.
Traction
The website claims more than 100 app teams use the platform and carries testimonials from the founders of Brainrot, Tsubasa and Aqimo, one of whom cites unlocking Google Ads for iOS apps and another same-day clean attribution data after an afternoon integration. No revenue, funding or headcount figures appear in the sources.

Market position
Describes itself as an app marketing attribution company serving apps that want to scale paid user acquisition without building measurement infrastructure; sources do not provide independent market share or ranking data.
Marketed differentiators are real-time device-level attribution at the ad level with end-to-end encryption, high attribution rates and custom attribution models; signal enrichment that unlocks additional campaign types and inventories; ad-specific onboarding and paywall personalization integrated with RevenueCat and Superwall; creator deep links with revenue-share payouts; and low operational overhead (no web funnels to build, no data duplication, no global tax or legal complexity to manage).
Technology
An SDK-based attribution stack available for Swift, Kotlin, React Native, Flutter and Unity, combined with tracking-link redirection infrastructure and a real-time signal-forwarding pipeline to ad networks. The company states it delivers real-time device-level attribution at the ad level using end-to-end encryption, supports custom attribution models, works across iOS devices, and serves ad-conditioned onboarding and paywall variants with an average latency under one second.
Go-to-market
Access is invite-only via a "request access" flow on the website and documentation. Distribution leans on certified integrations with major ad platforms and monetization tools, and on founder testimonials from app developers; a free tier serves as an entry point.
Mobile app and game publishers running paid user acquisition, from small teams testing the product on a free tier through to larger apps requiring enterprise support. Named testimonial customers include the founders of Brainrot, Tsubasa and Aqimo.
Geography
Not established by the sources; the product is delivered as software and the pricing page references geo-based pricing.
Risks & controversies
No controversies are reported in the sources. Notable profile risks: nearly all available information is self-published by the company, traction claims are self-reported and unverified, the product depends on third-party ad-network and platform integrations (Meta, Google, TikTok, Apple, Snapchat, AdMob, RevenueCat, Superwall) and on mobile-platform attribution rules, and access remains invite-gated. Name ambiguity also exists with unrelated entities using similar names (a 2012 US mobile ad optimization startup called AppStack, the AppStack Insider publication, and UPSTACK), which are not this company.
