Start.io

The business operates a dual-sided adtech model. On the supply side, it provides SDK-based monetisation and yield optimisation for app developers and publishers, earning a take rate on advertising spend and inventory monetisation. On the demand side, it packages mobile-derived audience signals into syndicated segments and curated supply deals that advertisers, agencies, and DSPs can buy and activate across programmatic channels. Value is created by collecting large-scale mobile signals, converting them into monetisable data products, and linking those insights back into media transactions.

start.io is a private US adtech company focused on mobile app and publisher monetisation, audience data products, and curated programmatic supply. Its platform combines an SDK for in-app ad delivery and signal collection with publisher monetisation tools, audience segmentation products, and curated marketplace offerings for advertisers and agencies.

The company makes money through a hybrid model: taking a share of media spend and publisher monetisation flowing through its ad infrastructure, and licensing or activating mobile audience data for advertisers, agencies, and DSPs. Its paying customers are primarily mobile app developers, website publishers, advertisers, agencies, and other programmatic buyers rather than end consumers.
