It also provides mobile audience segments for advertisers, agencies, and DSPs, built from first-party mobile signals.

Audiences can be activated across operating systems and channels including connected TV through leading DSPs. The platform supports GDPR, CCPA/CPRA, COPPA, and LGPD compliance.

Start.io serves app developers and publishers seeking to monetize inventory, as well as advertisers, agencies, and DSPs seeking mobile audience targeting.
