We work with the best, even if their logos must remain a secret.

As a LinkedIn expert, I had the opportunity to work with Sandra and witness her exceptional business mindset and ability to connect the dots in places others wouldn’t even think to look. Sandra is an absolute powerhouse – during several LinkedIn retreats and our sales program 30 Leads in 30 Days, she demonstrated what true drive, attention to detail, and proactivity look like in practice.

When something needs to get done, Sandra doesn’t just do it – she delivers results with tremendous added value for her clients.

In the field of market research – especially in pharma and retail – Sandra has outstanding insight, sharp strategic focus, and a drive you’d want on every project.

I truly value our collaboration, and if you’re looking for a reliable partner for market research who can think strategically and act quickly, Sandra is exactly the person you need.

I consider the collaboration with Sandra and Vantage to be highly professional and valuable. Their marketing perspective on our landing page helped us rephrase and simplify the messaging so that it became not only visually appealing but, more importantly, clear and convincing for our target audience.

Thanks to their input, the entire page creation process sped up significantly – from fine-tuning the content to finalizing the structure. Sandra impressed us not only with her attention to detail but also with her ability to quickly identify weak points and suggest practical solutions.

I especially recommend them to anyone who needs an external perspective on their communication and wants their online presence to come across as trustworthy, clean, and with a clear message.

I had the opportunity to work with Sandra and the Vantage team on a combined qualitative-quantitative research project in the form of a series of online focus groups with physicians. From the very first contact, it was clear that this was an exceptionally professional and experienced team. They dedicated a great deal of time to carefully preparing the discussion guide, organizing the groups, and collecting data, while flexibly responding to the needs of the project. I appreciate their responsible approach, reliability, and excellent communication. I can wholeheartedly recommend working with Vantage.

We conducted a representative survey on sexuality and intimate life in Slovakia with the VANTAGE research agency. And I must say right away that I am very satisfied and I definitely recommend using the agency’s services to carry out any survey that you want to use to find out important data for you.
You can use them in any of your activities.
I really appreciate how VANTAGE was able to empathize with the issue, perceive it, and formulate questions very professionally and consistently. I gained valuable information that I can use in education and when working with clients.
However, not only the formulation of the questions, but the entire process up to the presentation of the final report was both professional and human. Really great cooperation, thank you.

I have been working with Sandra on Pharma projects for years and I always look forward to this collaboration. Not only because these projects are interesting and rewarding, but mainly because of her. Sandra is an easy and pleasant person to work with, as she combines high professionalism with a human approach. She knows how to create an environment in which everyone feels heard and understood, which is a huge value in work. Her empathy and ability to read between the lines make her exceptional – whether when analyzing research data or communicating with colleagues. She can motivate, inspire and move things forward in a way that is natural and effortless. Working with her is not only professional, but also enriching on a personal level, which is why I can only highly recommend her.

Communication with the ladies from Vantage was pleasant, but at the same time very matter-of-fact and effective. The survey results were processed clearly and with an emphasis on what was most important for our company at that moment. Their work shows not only enthusiasm but also many years of experience. I highly recommend them. Zuzana Čechovská, CMO Novuma
