BrightLine

BrightLine operates a B2B ad technology model centred on interactive advertising for connected TV. It creates value by supplying proprietary ad formats, rendering and input-handling technology, and cross-platform deployment capabilities that let advertisers run interactive campaigns in streaming environments. On the supply side, it integrates with streaming apps and devices through its SDK; on the demand side, it serves brands and agencies seeking measurable CTV engagement. This positions BrightLine as a specialised infrastructure and campaign platform within the broader CTV advertising stack.

BrightLine is a private US ad technology company that develops interactive connected TV advertising products for brands, agencies, streaming publishers and app developers. Its core offering combines interactive CTV ad formats, a deployment layer built around its SDK, and tools that let buyers launch campaigns across streaming environments with engagement and brand-outcome measurement.

The company appears to make money through a mix of platform licensing, campaign execution fees and related charges tied to interactive CTV deployments. Its direct customers are business users rather than consumers: advertisers and media agencies use the campaign platform and self-serve builder, while streaming apps, publishers and ad tech partners use the SDK and integration layer to support interactive ad delivery.
