Trusted Web

Publishers under direct contract. Everything above stands on this.

C Wire is a contextual advertising company. We build and run the system that reads the web for advertisers: the crawler that reads pages, the record of what each page is about, the record of how each ad slot performs, and the software that decides where an ad belongs and what an impression is worth. This page is about the people who run it, the way we work, and where to reach us.

BrandDNA, CampaignDNA and MatchPersona turn your brand into the personas every campaign plans against.

What we believe

An impression is only worth buying when you know what surrounds it.

The individual page, read and vectorised in full: that is the belief the whole company is built on.

Around the product sits the supply: publishers under direct contract, screened against published criteria, with their ad slots checked one by one.
