      WordPress Website Design Review from Sascha Kienitz

      We build thermal imaging hardware, so our website is a product catalogue and it has to work flawlessly for our clients and distributors. For a long time the technical side of it was our weak point: changes were made directly on the live site, things broke, and nobody on our team could explain how the integrations actually worked. What we needed was not more marketing. We needed WordPress experts who treat the technical layer as the main job. That is the clearest difference I see between Osom Studio and the agencies we have worked with: with a marketing agency, development is something they also do, and the quality of it drifts over time. With Osom Studio their engineering is excellent. They started with a security and stabilisation audit, worked through it in a fixed number of hours, and reported against it. They test in a separate environment instead of on our live site, which sounds obvious and had not been our reality before. We have since moved the whole technical implementation of our websites to them.

      We have been working closely with OSOM for a few months now to improve various aspects of our website. They are a very professional, efficient and friendly team. They always understand what we want and carry it out with precision. I highly recommend working with them.

      WordPress Website Design Review from Jacob Haas

      Working with Osom Studio has been incredible! It's a rarity to find a team that's immediately responsive, can understand your needs and goals, and also offer multiple ways to achieve success. You can feel the care, craftsmanship, and effort placed into each step of the project. Their clear, detailed explanation of their efforts instilled us with the confidence necessary to trust them with projects we hadn't even intended them to take on. I'm excited to see where this partnership will lead us!
