What Start.io does
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.
Category differentiation
start.io is a mobile advertising technology and audience data company, not a consumer app or a general-purpose AI model provider. It is distinct from pure DSPs because it is anchored in publisher monetisation, mobile signals, and curated supply.
Strategic context
AI-supported assessment from the existing company research; distinguish interpretation from sourced facts.
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.
Company news briefing
Briefing updated:
Start.io continues to advance its mobile-centric omnichannel strategy under CFO Shachar Pessis and CRO Ravit Ross. Building on its targeting capabilities, the company launched 'Performance Audiences' alongside Curation+, an AI-native campaign planning tool supporting the Model Context Protocol to streamline workflows from brief to DSP activation. Furthermore, Start.io data has been utilised to analyse major sporting surges, while recent Prebid.js 11.22.0 updates incorporate ongoing adapter integrations to enhance deterministic signal activation.
Business model & monetisation
start.io uses a hybrid monetisation strategy combining ad-tech transaction take rates and data monetisation. It earns revenue from publisher monetisation and media flow through its SDK, ad serving, and supply-side tools; from licensing or selling audience segments with transparent per-segment pricing; and from curated private marketplace deals that combine inventory with audience data. This is supplemented by optimisation-led monetisation products that help publishers increase yield, supporting a share-of-spend and data-activation revenue mix.

- Percentage of media spend or monetised inventory revenue
- Audience segment licensing and activation
- Data licensing and per-segment pricing
- Curated supply marketplace deals
