What are the key stats related to Start.io's operations?
Start.io delivers hundreds of millions of ads per day across thousands of leading global apps, using AI to make digital advertising campaigns more efficient, effective, and precise. Our direct integration with thousands of mobile app developers gives us access to more than 100 billion first-party data signals per day worldwide. Marketers use these anonymized signals to understand and predict consumer behavior, identify new opportunities, and fuel business growth.
Is Start.io an SSP?
Yes. An SSP (supply-side platform or sell-side platform) is software that enables publishers and media owners to automate the management, sale, and optimization of their digital ad inventory. Start.io is an in-app mobile SSP that works with app developers to run global ad campaigns using programmatic demand and real-time bidding (RTB) auctions, delivering the most relevant ad for each impression.
What should an app developer (publisher) expect from integrating the Start.io platform?
The Start.io platform focuses on yield optimization for app developers, using machine-learning-driven pricing that adapts per impression to capture the highest CPM (the cost an advertiser pays for every 1,000 impressions) and incremental revenue.
What ad-quality and user-experience controls are built into the Start.io platform?
Start.io uses granular block lists, category filters, third-party creative-review solutions, and frequency capping to ensure that ads served inside your app meet brand-safety and user-experience standards.
How does Start.io create audiences and deliver targeting solutions?
Start.io's platform analyzes over 100 billion mobile data signals daily—including app usage patterns, location (where permitted), purchase intent, and device-graph attributes. Audience and segment targeting is built on observed behavior rather than probabilistic modeling alone, with optional enhancement through alternative-ID and identity-resolution partners.
What is the scale of Start.io's platform?
Start.io connects directly to thousands of mobile app developers and other SSPs, resulting in global coverage (with the exception of users in China). The platform delivers ads across mobile app categories and locations, reaching over 2.5 billion monthly active users on both iOS and Android.
Can Start.io's audiences be activated outside of mobile in-app?
Yes. Start.io's audiences can be activated across operating systems and channels, including connected TV (CTV), when accessed through leading DSPs.
Which privacy policies and regulations does Start.io comply with?
Start.io operates a first-party data framework built around explicit user consent and verifiable compliance with global privacy regulations. The platform supports GDPR, CCPA/CPRA, COPPA, and LGPD, among other local regulations.
