The coffee disappeared after a missed sales target. Brock Berry remembered the punishment well enough to bring it up years later, while discussing the workplace he and his co-founders were building at AdCellerant. “They took the coffee away,” he recalled. A company had found a way to make a disappointing number taste worse.
It is a small incident with an unusually long afterlife. Berry’s career has taken him through newspaper advertising, digital media operations and the business of making complicated advertising tools usable. Yet a coffee pot belongs in this story. His business depends on software, certainly, but also on understanding the people expected to sell it, operate it and pay for it.
Today, Berry is co-founder and CEO of AdCellerant, the Denver company that combines advertising technology with campaign services for media companies and agencies. The ambition is practical: give smaller businesses access to marketing capabilities that can otherwise demand more expertise and time than they have. The local advertiser has a shop to run. Becoming an expert in every advertising platform is a rather expensive second occupation.
The newspaper education
Berry grew up in Indiana, where he said he spent the first 23 years of his life. Colorado offered work opportunities and, by his reckoning, more agreeable weather. His education listing places him at Indiana University Bloomington from 1998 to 2002. The subsequent career was an education of another kind, acquired in sales territories, account conversations and media organizations negotiating their digital future.
His résumé includes advertising sales at The Herald-Times in Bloomington, territory sales work at The Denver Post, and later leadership roles at Clarity Media Group and MediaNews Group. At the Post, his responsibilities included major accounts. Those are useful places to learn that an advertiser’s enthusiasm for a proposal and an advertiser’s willingness to renew are separate achievements.
He also worked on products. At MediaNews Group, his projects included a Travel Widget and a Snow Report Widget and app. The snow report is a pleasingly concrete entry in a technology executive’s history: information with an immediate audience and a reason to return. Berry’s career was already moving between selling media and constructing things that made media useful.
At AdTaxi, he took on senior sales and operations responsibilities. Its expanding digital advertising business gave him experience managing campaigns and teams across markets. He had seen what media sales organizations could do when they had sophisticated digital products to offer. He had also seen how much human effort could sit behind those products. Both observations would matter when he started again.
A customer with a stake in the outcome
AdCellerant dates its founding to November 2013, naming Berry, Shelby Carlson and John Chamberlin as founders. Berry and Carlson had met as colleagues at The Denver Post; by the time they discussed the business together in 2017, they were husband and wife. Their shared professional background gave them a close view of the problem they wanted to tackle.
Small businesses could theoretically buy sophisticated digital advertising. Operating it was another matter. A media company might already have a salesperson who knew the business owner, understood the market and could arrange a meeting. The missing piece was often the ability to deliver a more complicated campaign without requiring everyone involved to become a specialist.
One early answer came through Voice Media Group, the publisher of alternative newspapers in several cities. The AdCellerant founders approached a partner with an existing sales organization and local customer relationships. They offered a way to earn equity through sales volume. Berry described an arrangement in which reaching the agreed volume earned the media company its share.
That deal gave the young company access to several markets through one relationship. It also rewarded the activity the business needed: selling campaigns. A customer had become a participant in the outcome. Later, Berry explained that other substantial partnerships helped finance growth, although the company did not repeat the same equity arrangement. The first deal had done a particular job at a particular moment.
“You need seven-figure answers; not six-figure answers.”

The work between a promise and a report
The software ambition needed financing. AdCellerant’s early services business helped provide it. Berry described managing digital campaigns for media companies while the platform was being constructed and developed. Revenue from doing the work helped support the machinery intended to make that work easier. It was a business with customers before it was a tidy software origin story.
The economics involved leaving room for the partner. In 2017, Berry described a services arrangement in which the media company retained 70 cents of each advertising dollar it sold. That is a historical description of the model, rather than a current price list. It shows the attention paid to giving the sales organization a reason to keep selling.
The platform followed the campaign’s working life: proposal, execution and reporting. Information about a business, its goals, geography, budget and timing informed a recommended plan. Orders then had to reach the advertising systems, and results had to return in a form someone could understand. For a customer, a collection of available tools can still amount to a collection of unfinished tasks.
By 2018, UI.Marketing was receiving industry recognition for bringing those tasks together. Its usefulness lay in connecting the stages, including the unglamorous handoffs between selling a campaign and running it. Berry’s proposition gave media partners a way to sell a broader service while retaining the local relationship. The technology had a human route to market, and the salesperson had something more substantial to take into the next appointment.
Keep the coffee
As AdCellerant grew, Berry and Carlson also had to decide what it would feel like to work there. Their 2018 account described a deliberate move away from strict attendance policing and toward a more relaxed environment. Culture became a recurring conversation as they considered offices and hired people.
Berry’s hiring questions were specific. What did a candidate actually enjoy doing? Did those interests match the responsibilities of the position? Would the person be comfortable in an open, playful workplace? The question connected individual motivation to the daily job.
The earlier punishment gave his account a memorable specificity. A sales organization needs results; the methods used to pursue them shape the workplace too.
Another partner at the table
The company’s capital story eventually acquired a new chapter. A recapitalization with Clearview Capital closed on December 12, 2023, and was announced the following January. Berry and Carlson continued to lead the business and retained significant equity stakes. The people who had helped build the company were staying involved in its next stage.
For Berry, this represented a way to pursue further growth with an investment partner. The transaction joined an established operating business to outside capital, years after the early arrangements that helped it get started. There is a useful distance between those moments: first finding partners willing to give a young company a chance, then choosing a financial partner for a business with an operating history.
The underlying offer remained recognizable. AdCellerant supplied technology, execution, training and sales support so media companies and agencies could offer digital services under their own brands. Keeping those elements together was central to the proposition. A platform can organize work; a partner still needs people who understand how to use it and explain the result to a customer.
The next sale still has to make sense
Berry’s recent public work has returned to the difficulty of using increasingly capable tools. In a discussion of his MarTech Memo appearance, he emphasized the friction agencies and mid-market businesses face when trying to run campaigns across fragmented platforms. Access alone leaves plenty of work unfinished. Strategic help and execution remain part of his answer.
His AI focus follows that same operational path: planning before the sale, managing orders and reporting after the campaign. The aim is to improve decisions and reduce the labor involved in connecting them. In the company’s September 2025 interview recap, he put his growth argument plainly: “Growth at this level comes from solving real problems for your partners.”
He also keeps writing. His public work includes pieces on connected television, coaching and programmatic advertising. In February 2026, he published a LinkedIn article about the year’s digital marketing leadership challenges; in September, his Streaming Media author page listed a piece on video measurement. The subjects change with the industry. The recurring interest is how advertisers and the organizations serving them should respond.
AdCellerant appeared again on the Inc. 5000 in 2026. For Berry, the continuing assignment reaches beyond a place on a list. Somewhere at the other end of the platform is a business owner deciding whether an advertising budget was well spent. The proposal must make sense, the campaign must run, and the report must help explain what happened. Years after newspaper sales, he is still working on that conversation.
