I first saw Lucia in action when she was presenting at UXCon Vienna and found it the most engaging talk at the conference. I reached out to her as we were at the start of our Experimentation journey and asked if she'd come and hold a workshop at our London office. From my first interaction with her she was warm, friendly and an absolute joy. I looked forward to my calls with her and we arranged the workshop. The feedback post workshop was brilliant, she'd managed. to get everyone psyched about Experimentation and providing the skills we needed to take it to the next level. We've since adopted a new Experimentation tool 'Kameleoon' from her recommendation and are on our way to becoming experimentation experts!! Thanks so much Lucia!

Lucia helped me prove the experimentation case within my company. They helped us ramp up experimentation for about 4 months, guide experimentation, setup and evaluate experiments as well to prove to higher management that it makes sense to invest in this capability

With limited CRO and A/B test knowledge internally, Lucia brought in a lot of hands-on knowledge which was very welcome. Both from UX/UI, tools but also process and workflow side of things she picked up the pace quickly and devised many hypotheses and tests. A pro-active and diligent person, with intricate knowledge of A/B testing and statistics, a very valuable addition to the project and team.

I had the pleasure of working with Lucia and her colleagues to upscale the experimentation engine in 2 of my positions, and I must say, her ability to provide solid advice in a remarkably short amount of time is truly impressive. The team offers accurate and precise observations that consistently elevate your marketing game to a whole new level. Whether you are looking to establish a foundation for new experiments or want to enhance your experimental strategies.

This team is the perfect partner. Not only she brings deep knowledge and subject expertise, but she also creates an environment that encourages open conversation and both productive and pleasant environment to collaborate.

I wholeheartedly recommend working with Lucia's agency to anyone seeking insightful guidance for the conversion rate optimization and experiments in marketing. Her expertise has been invaluable, and I am confident Lucia will bring the same level of excellence to any project.

We increased our conversion rate on our best visited pages. Lucia and her team helped us by bringing structure to our testing process. Setting up a test estimation (lead time/testability/priority), a backlog and schedule, and a brainstorm for generating new tests. We enjoyed working with each other, getting lots of tips and now getting up to speed with our test planning!

It was really great to work with Lucia and her team. Lucia made people enthusiastic and involved and, above all, without knowledge of experimentation and has taken our company to the next step. And also helped us with the automation. This made it easier and we could focus more, which improved the quality of the tests.

Lucia is great to work with, she has a natural drive to teach and help people which makes it very easy to work with her and she has abundant CRO experience and her particular strengths are in ideation, psychology and ramping up testing programmes. Highly recommend to anyone who is looking to take their experimentation programme to the next level and get great ROI!

Lucia has been great as a CRO Specialist. She has truly elevated and scaled CRO throughout the entire company, by consistently engaging people, improving processes, applying her sharp analytical mindset, and displaying an eagerness to test and challenge the status quo. She adeptly combined her extensive knowledge of data and psychology into experiments that made a great impact. By enabling, empowering and motivating the team, Lucia has enabled us to significantly amplify our testing efforts, resulting in more than doubling the number of tests conducted. She also fostered a sense of enthusiasm and dedication among the team members. Her continuous refinement of processes and commitment to involving everyone has established a strong foundation for expanding the CRO program even further.

Lucia is an amazing asset to your team. Lucia is very knowledgeable on all aspects of validation and perfectly facilitates a dual track agile way of working for your product & development team. She streamlines all validation requests, and really gets to the bottom of what you want to learn and which metric you want to influence. She also helps the non-product peeps with this way of working, bringing a CXO / CRO mindset to marketing, sales and content teams. She ‘scales’ herself in this way, making sure that every team is able to validate. Furthermore, she is such a friendly, calm and pleasant colleague to work with. Her energy, passion and drive really helps with advocating for experimentation. And she always finds fun and new ways to share and present results, creating visibility and company-wide appreciation for this way of working. In short, highly recommend working with her!
