Featured Client Reviews
"Creative, trustworthy, top-class company!"
"The collaboration was very disappointing. From the very beginning, I expected a professional approach and clear communication, but unfortunately, I encountered the complete opposite. For a long time, advertising campaigns were run at around 2,000–3,000 PLN per month, which was acceptable to me. To my surprise, at one point, without my knowledge or consent, the budget was increased to 9,697.81 PLN. I only learned about this after the funds had been spent. Of this nearly 10,000 PLN, the campaign generated sales of 14,261.99 PLN, which, after deducting the costs of products, commissions, and the service itself, translates to zero or even negative financial results. The level of service was also very poor—there was a lack of contact, reporting, or analysis of results, and responses to inquiries were terse and general. It was clear that no one was actually monitoring the campaigns or analyzing their effectiveness. I felt like everything was automated, without any strategy or oversight. My comments and requests for clarification yielded no concrete results. In short, it was a waste of money and time. I don't recommend it, especially to companies that expect transparent collaboration, budget control, and real commitment to campaign results."
"I'm very satisfied with our collaboration, which has lasted over 1.5 years. Their Google Ads campaigns are conducted at a high level. I can wholeheartedly recommend them to other companies looking to spend their money effectively. Excellent communication with the account manager – a big thank you to Karolina."
"I highly recommend working with the Sempai agency. We've been working together for several years. I especially appreciate the excellent communication with the advisors, who diligently answer our questions and concerns, which aren't always straightforward. This makes it much easier for us to navigate topics we typically only know theoretically."
"Sempai is a truly reliable partner. The team always listens to our needs, proposes effective solutions, and responds quickly to changes. They also have excellent communication and a high level of commitment. We highly recommend working with them!"
