Software Development Review from Michael Meyer

We were so positively surpised and happy about Sigmas services - as usual I might add. It is a pleasure working with their software engineers. After we provided a briefing, the effort estimation came right away. Shortly after the project started we could see first tangible results. The code quality was excellent and comprehensive. Minor feedback was implemented right away. What can I say more: 10 out of 10 points!

Technical SEO Review from Valeriy Fomenko

We looked into WiserBrand because we needed help with AI Visibility and GEO. Their team showed they really understand how AI search is different from regular SEO and explained a clear, practical way to boost visibility in AI-powered search. They explained their methodology for AI search visibility, positioning, content strategy, and technical SEO in an easy-to-understand way. What impressed us most was their focus on practical recommendations rather than generic advice, along with clear communication throughout the process. After our experience, we think WiserBrand is a knowledgeable and professional team for any company looking into GEO and AI Visibility.

AI Consulting Review from Alina Krucheniuk

We worked with WiserBrand for AI consulting and strategy on a co-living hospitality platform we were developing. Once the main web and mobile systems were set up, we wanted to see how AI could help us reduce manual tasks and streamline our internal processes. WiserBrand pointed out where AI agents could have the most impact in both resident-facing tasks and our internal operations. They reviewed areas such as resident support, onboarding paperwork, email and invoice management, reputation management, and operations monitoring. They gave us a clear plan that included the best use cases, how to integrate AI, where we still needed human review, and steps for rolling things out in phases. This helped us see which tasks we could automate right away, which ones still needed people involved, and how to add AI without causing problems for our current platform. We knew how it would change our daily work and what to focus on next. The team was organized, practical, and easy to work with, so the whole process was smooth from start to finish.

Web Design Review from Jorij Abraham

We hired WiserBrand as they came strongly recommended by one or our strategic partners. The recommendation was absolutely right. We are no amateurs with 6,5 million unique visitors per month but we learned a lot how we could further optimize our website both from a search engine optimization as well as user experience perspective. The project was completed on time and within budget with several major insights. I can strongly recommend WiserBrand. Feel free to contact me via LinkedIn if you have any questions.
