Carbon Ads

Carbon Ads is an ad tech company that connects advertisers to users through targeted verticals called Circles, which are hand-picked publishers in specific niches. They have been active since 2010 and are run by BuySellAds. The network focuses on developers, designers, founders, and people building with AI tools.

The platform claims to have 350+ hand-picked tech sites and over 900 total active sites. They state that viewability is 95%+ across the network and they review performance site by site to remove underperformers. The company has served over 49,000,000,000 impressions.

Typical CPM rates range from $1.50 to $2.30, though this varies based on audience geography, engagement, and advertiser demand. No rate is guaranteed, and earnings are deposited into BuySellAds accounts within 30 days of the month closing, typically around the 25th of the following month.

Publishers must display only ads from the Carbon Ads network on their site and cannot use Carbon as backfill for other networks. The company evaluates applicants based on ad relevance, monthly page views, active maintenance, and current capacity. New sites are reviewed within 7 business days.

The target audience consists of English-speaking developers and designers, primarily located in the United States, Canada, and Europe. These regions usually have the strongest demand and highest fill rates, though other regions are served when advertiser demand allows.

A client success manager oversees every campaign, planning volume with the advertiser and watching delivery and performance in a real-time dashboard. Advertisers can see daily impressions, clicks, and click-through rate by creative to act on the numbers shown.

Carbon Ads offers Cover, a high-impact native ad format with rich visuals and a clear call-to-action that lets viewers interact with the creative. They also provide CircleCI and CodePen as examples of sites used to reach enterprise software teams.

Some reviewers on Trustburn praise the team for being helpful, responsive, and professional, noting that the services drove significant traffic and sales increases. Others mentioned the rates are affordable and the setup process is easy to manage.

The company states they have paid out over $120,000,000 to publishers through BuySellAds. They also mention that FullStory and HelloSign have used their native advertising campaigns to build status in developer communities.

To start, advertisers must fill out a form providing their work email, first name, and product URL. Publishers need to submit their website URL and traffic statistics through an application form to request an invitation.

The company claims to isolate high-intent technical audiences without bleeding budget on unqualified impressions, bypassing inflated costs of generic ad networks. They emphasize value over a simple click-through ethos in their placement strategy.

As of September 1, 2026, earnings are deposited into BuySellAds accounts within 30 days of the month closing, and become withdrawable within 60 days. Open Collective payouts run on a separate quarterly schedule instead.

The network has been active since 2010, making it over 16 years trusted by publishers and advertisers. They have over 350 active sites and claim to have funded the independent web with significant payouts.

The FAQ was last reviewed on October 25, 2026, and the Trustburn rating is 4.1 out of 5 from 8 reviews. The company provides a media kit and creative brief for those planning a campaign.
