Thyago Guimarães has spent years working in digital marketing, copywriting and online business, but one of the markets he has increasingly focused on is domain investing. Through Domínios Lucrativos, he teaches a Brazilian audience how domains work as digital assets, how to identify names with resale potential, and how investors in Brazil can participate in a market where many of the buyers and transactions are international.
That caught my attention because most of the domain investors I speak with are based in the United States, Europe or other established pockets of the industry. We do not hear nearly as much about what the market looks like from Brazil. I wanted to talk with Thyago about how he discovered domain investing, what his students are looking for, how Brazilian investors approach the business differently, and where he thinks this market is headed.
Sully: Thyago, let’s start at the beginning. How did you first discover domain investing?
Thyago: Since I speak English, I really enjoy consuming content from American influencers. One day, while doing some market research, I stumbled upon a video about domain flipping. The logic behind the niche really caught my attention: if there are few domains available, they tend to appreciate in value. I started researching, took some online courses, and bought some educational materials. After studying, I started very slowly, testing the waters. I bought a few wrong domains at first out of excitement, but I also made some great deals; I once generated over $8,000 in revenue in just 15 days by selling two domains in a short span of time.
Sully: What led you to create Domínios Lucrativos and begin teaching other people how to invest in domains?
Thyago: That’s an excellent question. The domain flipping market isn’t very well-known in Brazil; it involves low investment and low risk. When I started making money from it, a friend of mine named Paulo asked if I could teach him how to make money with domains too, so I said yes. After that, I had the idea to record a video for my YouTube channel, and my followers asked me to create this course. It was a great experience.
Sully: How would you describe the domain investing community in Brazil today? Is it still relatively small, or is it growing quickly?
Thyago: It is a small market.
Sully: In the United States, many investors focus heavily on .com. How important is .com to Brazilian investors compared with .com.br?
Thyago: The Brazilian flipping market is still very small, and there are many domains available, so they don’t tend to appreciate as much as .com domains do. Furthermore, since it is an international market, .com domains have demand worldwide. My portfolio includes several .com.br domains focused on technology, AI, startups, and betting; I believe this remains the best market for .com.br domains.
Editor’s note: Since January 2025, Brazil has required licensed betting operators to run their sites on .bet.br domains, so betting-related .com.br names are more likely to appeal to affiliate, tips and news sites than to the sportsbooks themselves.
Sully: Are there certain types of domains or keywords that sell particularly well to Brazilian businesses?
Thyago: Those related to finance and technology are the top performers; I would highlight terms like “Bank,” “pay,” “crypto,” and “app.”
Sully: What is the biggest mistake you see beginners make when they start registering domains?
Thyago: Rushing to buy every domain that seems good; conducting market research and analyzing past and future trends is the better approach.
Sully: Do you encourage your students to concentrate more on hand registrations, expired domains, auctions or buying domains from other investors?
Thyago: New registrations are good but very hard to find. For my course and mentorship students, I always tell them to focus on expired domains and auctions, as they are easier to find and require less effort.
Sully: What role does outbound marketing play for your students? Do you teach them to actively contact potential buyers or wait for inbound inquiries?
Thyago: I teach both approaches; platforms like Atom make this process easier.
Sully: Are there obstacles that make international domain transactions more difficult for Brazilian investors, such as language, payment systems, currency conversion or access to certain marketplaces?
Thyago: Not anymore; with AI and automatic browser translators, it’s easy for everyone, even those who don’t speak English. Regarding payments, PayPal makes things very easy, and the funds are received instantly here in Brazil.
Sully: Looking five years ahead, what do you think the Brazilian domain investment market will look like, and what opportunity do you think investors outside Brazil may be overlooking today?
Thyago: Brazil is one of the hottest and most affordable markets in the world for technology and finance. I believe that once the domain craze truly hits the Brazilian market, we will see significant opportunities in domains ranging from 1 to 5 letters, as well as in domains related to branding, finance, crypto, payments, and AI.
