Grupo Technos is one of Brazil's largest watch groups. The company runs four direct-to-consumer e-commerce sites: Technos, Fossil, Euro Relógios, and Time Center. All four sit on deco. Thainá joined as e-commerce manager and inherited the whole portfolio.
Thainá's team is small. Two people operate the frontend across all four sites, and the rest of the e-commerce organization splits across media, CRM, and planning. Anything more than a content swap was scoped through the agency, and the in-house team didn't have an easy way to act on opportunities the moment they appeared. When deco introduced a developer agent inside the CMS in March 2026, Thainá decided to see how much she could move on her own with it before handing it to anyone else.
Rio Fashion Week was returning to the calendar after ten years, and Euro Relógios was invited to take part, with five influencers covering the event across multiple days. The invitation arrived on a Thursday, and the event opened the following week. The window was tight. Thainá opened the developer agent and started writing the brief directly, in plain Portuguese, the way she would describe the work to a teammate. Her main concern was that she would still need a developer to translate her requests into technical terms.
What came back surprised her. She had asked for vertical blocks for video. The agent built a carousel where each block could be toggled on or off, with an optional link out to the matching product, which she had not requested. The brand colors, header, and footer carried over from the rest of the Euro site without her specifying them.
“It came back as a carousel where each block could already be activated or not, with a link out to the video's product. That was something I hadn't asked for, but it's the ideal.”
Thainá kept iterating in the same conversation, asking for tighter copy, color tweaks, and a different placement for the reels carousel. Two hours after she opened the tool on Friday morning, the page was live, well before the event opened in Rio. You can see it at eurorelogios.com.br/rfw-editorial.
What stood out for Thainá was how much the agent already understood before she typed anything. Grupo Technos has four brands inside one CMS configuration, each with its own catalog and visual identity. When Thainá opens a chat from inside Euro, the agent works in Euro's context: its typography, its palette, its product feed.
“I have four stores plugged in. It's the same setup, a multi-store schema, and it understands each brand individually. I gave a prompt for Euro and it considered everything inside Euro. It didn't pull anything from another brand or reflect it on the wrong one.”
The catalog awareness changed what the editorial page could do. Each photo or reel in the mosaic could link to a product page in the Euro catalog, and the agent surfaced those product URLs from inside the site as part of the same conversation. A reader scrolling through one of the influencer days could click from a styled photo straight to the watch shown in it. The work the agent picked up was not a feature. It was an operating context.
The Rio Fashion Week page was the first big test. The same approach has shown up across the team's work since. Thainá needed a new lead-capture page for Technos with a birthday field kept optional on the form. The agent built the layout, balanced the image and the form so they carried the same visual weight, and supported video in the same media slot, a pattern already in use on other Technos pages. The same brief would normally have run roughly 17 to 18 hours of design and development end to end. With the layout built in-house through the agent, the remaining work, the connection to the customer database, came in at around 5 hours.
The cultural change is harder to measure. The reflex of "we can't ship this" or "we don't have time" is being replaced with "this might be doable." The team is acting on moments it would have once let pass. Thainá's assistant, who wasn't building pages before, now produces landing pages on her own.
“I optimize my team's time much more now, and regardless of the title of the person sitting there, they're producing. Today my assistant produces landing pages on her own.”
The relationship with the agency shifted too. Briefs leave the team more specific now, and the agency handles platform-side integrations and the deeper technical work while layout and content stay in-house.
Before joining Grupo Technos, Thainá had encountered deco at a previous company that decided to skip it, on the assumption that a different commerce platform would not need it. Her image of deco was specific: a frontend host that helps VTEX-based sites load fast. Working with it day to day changed that view.
The team runs A/B tests on the platform. They host video and image assets in deco. They operate the developer agent. The list of things they reach for inside the CMS keeps growing, while the underlying commerce platform matters less to their daily work.
“Even if we did move platforms in the future, for me the move is: unplug from the current platform with deco, and plug into the new one with deco. The conversation isn't 'do we keep deco.' It's that deco is the part that stays.”
The team is now setting up blogs for Technos and Euro with deco's autonomous blog agent. Both brands had blog on the year's roadmap but never had the people to staff a writer. The agent produces first drafts that the team validates for tone and accuracy. And because the blog sits inside the same site, the agent surfaces relevant products from the catalog inside each article instead of sending readers off-site.
Thainá has also shared with us where she would like to take this further. Euro Relógios is going through a brand refresh, and she has been thinking about handling the new homepage, landing pages, and brand updates through agents. The tests so far have made her think it is possible.
“The idea is to do all the rebrand updates, new landing pages, and the new homepage using only the agents. Basically redesign the whole site through them. From the tests we've done, I think it'll work.”
What Thainá is describing is something we keep hearing from teams operating at this scale. When the people closest to the brand can act on their own, the whole calendar changes. We will be sharing more of these stories in the coming weeks.
Grupo Technos didn't change vendors or shrink scope. They put more capacity to act in the hands of the people closest to the brand, and the campaign calendar started catching up. If your CMS is the bottleneck for the work your team wants to ship, we'd like to talk.
