SinComisiones is a price comparison tool that started with a focus on finance (bank accounts, credit cards, mortgages, etc.) but has since expanded into new sectors like telecommunications, insurance, and energy.
Gabriel Rodríguez Lorenzo and Miguel Otero Vaccarello have known each other since they were young. Friends since high school, they always shared entrepreneurial aspirations and made several attempts to start businesses together, though without much success. “However, after Miguel proposed creating a website related to finance, we embarked on the adventure, and this time, we succeeded,” Gabriel recalls.
But that success wasn’t easy to achieve. During the COVID pandemic, they were offered sponsorships and advertisements for thousands of payday loans and credit card offers, which they declined for ethical reasons. “This was a tough decision because we could have made a lot of money very quickly, but I always think long-term, not short-term,” Rodríguez explains. Soon, they realized they made the right choice, and as a complementary part of the company—which essentially helps individuals counter abuses from more powerful entities—they established a law firm. This firm has helped over 5,000 people recover the money they were unfairly charged.
Why did you start with a focus on finance?
When I (Miguel) turned 26, I started getting charged fees on the typical account I had as a university student. While researching ways to avoid these fees, I found very little useful information. That’s when we decided to create SinComisiones, a website that simplifies finance for everyone, always from the user’s perspective. I had knowledge of building websites from working in marketing agencies, and Gabriel had business expertise from an MBA he was completing that same year, so it was the perfect time to start.
What sets you apart from other comparison platforms? Why choose SinComisiones over others?
SinComisiones is the most honest comparison platform on the market. Our key differentiator is that we never recommend products that could harm our users, such as payday loans, revolving credit cards, or even certain unregulated brokers. We take this very seriously—it’s fundamental to us.
Additionally, considering all the advancements happening in AI, we see a strong need to offer more than just product analyses and comparisons. That’s why our website is constantly evolving. We’ve developed tools like a product comparator, a search tool, and a calculator, which very few comparison platforms can offer, and which make our users’ lives easier.
Why did you decide to branch out into new sectors? How is that process going, and how do you decide which ones to pursue?
We’re ambitious, and to become the best comparison platform in Spain, we can’t limit ourselves to financial products. We need to offer everything, from telecom plans to any type of insurance. We want our users to turn to SinComisiones whenever they need to make a consumer decision, no matter the category.
Why did you refuse to advertise payday loans, credit cards, etc.?
For me (Gabriel), I’ve had family members affected by these kinds of credit cards. They were sold as seemingly good products in shopping centers but turned into debt spirals that are incredibly difficult to escape. It can take up to 50 years to pay back just €10,000 of credit. Being fully aware of how harmful these loans were, we flatly refused to promote them.
How do you make money then? How do you decide what to promote and what to reject? What are your limits?
We partner with the companies featured on our site. Through various compensation models, they reward us for referring customers.
When it comes to deciding what to recommend, it’s straightforward. We always ask ourselves one simple question: Would we use this product ourselves? If the company is unreliable or the product could harm consumers, it’s immediately removed from our site.
How do users respond to that decision? What feedback have you received?
The response has been overwhelmingly positive. Users feel we genuinely look out for their interests, which builds a high level of trust in our brand.
Who are your users, and why do they come to you? What is their profile?
Our users are mainly people between the ages of 30 and 50, though we have visitors across all age groups. They come to us whenever they face any kind of problem—whether they need advice on their mortgage, want to switch their home internet provider, or have been charged bank fees. Our job is to guide and inform them as best we can.
How do you expect your audience to grow as your offerings expand? How do you reach users, and what are your growth goals for 2025?
We primarily reach users through Google, the top organic channel. We’re SEO experts and focus on answering any questions users might have.
Our expectations are high, and 2025 has started strong since we migrated to the new SinComisiones website. We hit an all-time traffic record of over 175,000 unique users in January. However, 80% of this traffic comes from our finance vertical. As our new sections gain traction, we aim to end the year with around 400,000 monthly users.
How and why did you create a complementary law firm? What has its journey been like so far?
When we decided not to promote abusive financial products during the pandemic, many users reached out to us via our chat seeking advice on bank-related abuses. This led us to research concepts like usury, lack of transparency, and compound interest, and we realized we had to provide solutions for our users. We started by collaborating with various law firms but eventually decided it was better to create our own.
What are the most common abuses you have to defend against?
We generally tackle cases of usury—credit or cards with interest rates far higher than legally allowed. We also handle issues with transparency in contracts where users don’t fully understand the financial implications. Additionally, we fight against abusive bank fees, such as overdraft fees.
Why do these abuses occur? Do you see a change in corporate attitudes, or are these abuses increasing?
Abuses often happen due to users’ lack of knowledge. Many people don’t understand basic economic concepts, which is why we prioritize making basic financial education accessible to everyone. Unfortunately, these topics aren’t typically taught in schools, but most Spaniards will have to deal with terms like APR, Euribor, or CPI. Understanding these helps people make better decisions. Knowledge is power, and unfortunately, abuses will always exist. That’s why our role in defending against them is so important.
How do you expect the law firm to evolve in 2025?
Spanish courts are overwhelmed, and bank-related claims take a long time to resolve—on average, about two years. In 2025, we have many pending lawsuits that are expected to move forward, making it a year of reaping the rewards of our efforts over the past years. If all goes well, we plan to explore new avenues, such as filing lawsuits related to the right to honor, to better defend our users.
And what about SinComisiones? How do you see the platform in the medium to long term? What are your expectations and plans?
We are very ambitious and aim to become the best comparison platform in Spain. To achieve this, we know we must innovate and invest in creating the best tools for our users. This is our main focus. Additionally, once our tools are fully developed, we plan to expand our model to new markets, such as the United States and Latin America.
