Streamr.ai (Magnite)

Category: AI Video

Make a TV ad from a URL and run it on streaming.

Streamr.ai generates connected-TV and online video advertising, then activates it. You can point it at a website or product URL and it produces a finished TV-format ad, or start from templates, storyboards or an existing image. Named features include Creatives for AI generation, Storyboards, Image-to-Video, a Social to CTV model that adapts creative you already run on social into TV format, and Campaigns, which handles the compliance checks and format requirements CTV demands and pushes the ad live on streaming inventory. There is also GenAI Labs for bespoke work with their team. Magnite, the largest independent sell-side advertising company, acquired Streamr.ai in September 2025, and the product now sits inside Magnite with its founders; the strategy is increasingly to distribute the technology through agencies, retail media networks and publishers rather than only direct to advertisers.

Our verdict

The creative generation is the genuinely clever part: going from a product URL to a formatted, compliance-checked TV ad in a couple of minutes removes the single biggest barrier to smaller advertisers using CTV at all, which has always been production cost rather than media cost. The Social to CTV model is the smartest feature, taking creative you have already proven on social and reshaping it for the living room. Being inside Magnite now is a credibility upgrade rather than a risk, and the named case studies are real businesses. Two things to be clear about before you get interested. There is no published pricing at all, just a credit model and a sign-up, so you will need a conversation. More importantly for a UK reader, everything about this is US-centric, the case studies, the inventory, the SMB market data, and we found no evidence of UK CTV availability, so check that first if you are buying from here. Post-acquisition the direction also favours Magnite's partner channel over self-serve.

Best for: Teams running US connected-TV campaigns who need broadcast-format creative produced quickly, and agencies working with Magnite inventory.
