Before João Brognoli could get much use out of his first office, it had already become expensive. Three days after renting the room and founding his company, he broke the lease. The penalty was R$5,000. He had not even used the space. Years later, recalling the episode, he acknowledged that the money had been missed. Entrepreneurship had presented its first bill with admirable punctuality.
The detail survives because Brognoli told it, even after there were acquisitions and awards to discuss. It gives the beginning of Duo a useful texture. Here was a business starting below zero, with an address that had ceased to be useful almost immediately. The founder would eventually write a book called O Ambiente Muda Tudo, or The Environment Changes Everything. His first environment certainly changed the balance.
A small first step, repeated
Brognoli identifies September 10, 2013 as Duo’s Day One. The setting was Caxias do Sul, in Brazil’s southern state of Rio Grande do Sul. The early business developed applications; its services expanded into websites, digital marketing and the work of an agency. His brother, Luís Otávio, became a partner the following year. The enterprise acquired both a wider brief and a family connection.
On its eleventh anniversary, Brognoli returned to the language of small beginnings. A new client, an employee, another business, an investment: each had required its own first step. He counted 4,018 days of thinking about Duo. The calculation was unusually specific. Founders tend to measure anniversaries in years; he had apparently kept the receipt for every day.
There is a technical beginning behind the executive one. Brognoli has described teaching himself programming and studying design. Those skills meant he could put a website together himself. Over time, the work around the website grew larger than the work on it. That change would become a recurring feature of his career.
Buying the skills the next brief needs
By February 2024, the business had become a group that included Duo Studio, Premium, Consultoria Digital, Let’s Flow Digital and Conexorama. The addition that month was Start BI, a Caxias do Sul company specialising in business intelligence and data analysis. Its founder, Valber Subtil, brought a different discipline into a marketing organisation.
The transaction was expected to integrate approximately 25 Start BI clients into the group’s portfolio. Brognoli described data-led planning as a longstanding ambition. The attraction was a capability that could extend what the usual marketing tools provided. An agency could make and distribute a campaign; the acquisition added expertise for understanding the information around it.
The group reported R$30 million in revenue for 2023 and set a R$50 million goal for 2024. These figures describe different things: one was a reported result, the other an ambition. Together they show the scale at which Brognoli was now working. A founder who had once built websites was making decisions about which other businesses belonged alongside his own.
Some partnerships begin with an audience
Let’s Flow illustrates another route to expansion. In 2023, Grupo Duo&Co joined Natalia Beauty in a new agency aimed at beauty businesses. The partnership brought together a public-facing brand and a group with marketing operations behind it. Brognoli’s part in the announcement was practical: clients would arrive gradually.
He explained that Natalia and the group’s operations chief, Monique Areze, would participate actively as projects came aboard. The initial expectation was 20 to 30 clients. Even in a launch built around a recognisable name, he was talking about the pace at which people could do the work.
The distinction matters to his story. Expansion has taken several forms, including acquiring specialist expertise and establishing a venture with a partner whose audience already exists. Each arrangement asks something different of the founder. Buying an analytical business and building a beauty-focused agency may share a spreadsheet, but they do not share a customer conversation.
The trophies have different names
Duo received RD Station’s Agency of the Year recognition in 2022, 2023 and 2024. In 2024, there was also recognition from Share. The following year brought Agency of the Year at the EWI Global Awards in Montreux, Switzerland, during an event at the Château de Chillon.
It is tempting to compress that sequence into a single streak. The actual version is more interesting: repeated recognition from one industry organisation, followed by recognition in other settings. Brognoli’s business was being seen by different audiences. The competitions were different, too.
The company’s account of the Swiss occasion included members of BRAIN and Ambience Club, the mentoring communities around him. That detail brings the awards photograph closer to his working life. By then, the people travelling in his orbit included business owners who knew him as a mentor as well as people who knew the agency.
The calendar becomes a business problem
In the opening days of 2024, Brognoli described an unfamiliar planning challenge. Budgets, targets and projects had already been organised. His attention had shifted to dates. Speaking engagements, mentoring, events and other commitments had put something in every month of the year.
There were logistics to consider, including how reliably flights could get him in and out of particular airports. It is a revealingly unromantic detail. Public speaking looks like a person with a microphone. Behind it sits someone considering whether the aeroplane will land.
He connected that crowded diary to a goal from the previous year: sharing knowledge and expanding his market. BRAIN Mentoria and Agency Club give that work an organisational form. The former is his business mentoring initiative; the latter serves agency owners and involves fellow founders including Daniel Imamura and Cristian Ross. His audience had grown beyond people purchasing agency services.
Taking the microphone out of the studio
Brognoli also became a regular host. Conexão Duo addressed marketing, sales and business, with interviews and short episodes. By 2026, his public work included the Muda Tudo podcast. His own link page directs visitors to an episode with Toguro, alongside mentoring programmes and his book.
The format was changing. In June 2026, he described interviewing Jordy of Gava Gourmet while making barbecue, visiting industrial businesses and sharing his routine through YouTube vlogs. The intention was to show business as it was experienced at work. A conversation could now come with a factory floor or something cooking nearby.
He also distributed two- to three-minute audio pieces on Spotify, covering subjects such as sales, goals and recognition. Long interviews and short observations occupied different corners of the same public presence. He was giving people several ways to encounter his ideas, including one brief enough to fit before the working day had properly begun.

The founder moves to the other side of the table
In March 2026, Brognoli introduced Ambience Private Equity. The investment club was structured as a corporation with 15 investors. It sought minority stakes, with participation through boards rather than direct management of the businesses. The operator was adding a different kind of responsibility.
Its announced twelve-month ambitions were up to R$20 million in investments and a portfolio reaching R$250 million in combined revenue. Those were the targets at launch. They describe the size of the undertaking he wanted to build, rather than money already deployed or turnover already achieved.
For Brognoli, the move followed experience with entrepreneurs whose businesses had demand and operations, but needed capital or support to expand. His account of his own development was direct: technical ability had given way to a stronger interest in management and capital allocation. The work had changed, and he was describing it with a new vocabulary.
“O marketing foi um meio.”
João Brognoli · “Marketing was a means.” · Translation from Portuguese
An old acquaintance, a new stake
One investment carried a connection much older than the transaction. Gustavo Bertin, a founder of Grex, had known Brognoli at school. More than fifteen years later, they reconnected. Grex developed software for managing churches, including attendance, events and finances.
Brognoli disclosed an investment for 20% of the business. In explaining the attraction, he emphasised a defined community with particular needs. The market’s specialisation was part of the appeal. It was also an instance of something he repeatedly values: the people beside him in a venture.
The relationship supplied an introduction, but there was a product and a customer problem to consider. That combination makes the episode more useful than a general instruction to network. An old acquaintance had built something specific. Brognoli saw a business he wanted to join.
Back to the question of a room
In August 2026, he described plans for a 700-square-metre São Paulo space on the Marginal Pinheiros. It would accommodate more than desks. His plans included podcast recording, events, talks and products from businesses in his network. Even the coffee at reception would come from a brand within that circle.
His books make the same interest in surroundings explicit. O Ambiente Muda Tudo was followed by his participation in Não Existe Plano B, a collaborative book launched in 2026. In a September essay, he argued that useful connections require time beyond daily execution. A completely packed schedule can leave little room for the conversation that changes a business.
The unused first office and the planned São Paulo space belong to the same career, thirteen years apart. Brognoli now imagines a room where businesses, audiences and partners can meet. The coffee has a business connection. The microphone has a purpose. This time, there is quite a lot he wants to do before leaving.
