CUSTOMER STORY | MOBILE ADVERTISING TECHNOLOGY
How EVIZI™ supported Vungle, now Liftoff, with cross-platform SDK development, daily quality engineering, and automated testing across mobile and web environments.
Company Overview
Liftoff, formerly Vungle, is a publicly traded performance marketing and monetization platform serving the global mobile app economy.
The company was formed through the 2021 merger of Liftoff and Vungle, combining mobile user acquisition, creative technology, analytics, SDK-based monetization, and publisher services within one platform.
As of March 31, 2026, 167,814 apps had integrated Liftoff’s SDK. Through these integrations, the platform connected to approximately 1.4 billion daily active users worldwide in the fourth quarter of 2025.
Liftoff employed 652 people across 12 offices in 10 countries and reported $220 million in revenue for the second quarter of 2026, representing 35% year-over-year growth.
Industry
Mobile Advertising and App Monetization
EVIZI™ Engagement
Platforms
Vungle’s advertising platform extended across several interconnected product areas.
Creative Labs enabled teams to create and customize advertising formats. Cross-platform SDKs were integrated into publisher applications to serve advertisements across iOS, Android, Windows, and Amazon devices.
Publishers also relied on a web-based dashboard to configure their applications for monetization, while server-side systems supported ad creation and delivery.
Supporting this ecosystem required consistent development and quality engineering across mobile SDKs, web applications, advertising templates, integrations, and device environments.
Our specialized team provided engineering and testing support across three primary areas:
Cross-Platform SDK Development
EVIZI™ engineers contributed to SDK development across multiple platforms and programming environments:
The team also developed test applications for Android, iOS, and Windows to validate SDK functionality in platform-specific environments.
Manual and Automated Quality Engineering
The team provided daily manual and automated testing for new SDK builds.
Then they developed additional automated tests across web and mobile platforms using Python, Selenium, Appium, and pytest. Kobiton cloud devices supported mobile-device coverage, while Jenkins helped integrate testing into the delivery process.
Okta, App Center, and TestRail were also used to support access, application distribution, and test management.
Integration and Ad Format Testing
EVIZI™ developed integration tests for SDK version 7 and created unit tests for SDK functionality.
The ad-format team performed daily testing of new advertising templates and system updates, including manual validation before templates were released to production.
This helped establish consistent quality coverage across the SDKs, advertising formats, and supporting product systems.
The engagement delivered concrete quality engineering capabilities across Vungle’s product ecosystem:
Rather than treating quality as a final release step, testing was incorporated into the ongoing development of SDKs, advertising formats, and supporting applications.
As Vungle moved toward its combination with Liftoff Mobile, EVIZI’s involvement also expanded.
The team began a new engagement with GameRefinery, then a Vungle company, whose platform supported mobile game development, market research, and advertising decisions using data on mobile game genres and features.
This expansion extended EVIZI’s work beyond the original SDK and ad-format scope into another part of the company’s mobile technology ecosystem.
EVIZI™ helped Vungle establish development and testing coverage across the SDKs, devices, web applications, and advertising formats connecting publishers with its mobile advertising platform.
Today, the company operates as Liftoff and the engineering requirement remains highly relevant: when software must work across platforms, applications, devices, and integrations, quality cannot be confined to a single testing phase.
