      Unfortunately, there are no small, green omnipotent children, nor are there forest rangers, but there are a lot of smart people here and it kinda looks like an academic building in terms of architectural style. Just think twice before throwing a handful of leaves at someone. However, there are sentient fungi here, so take that as you will.

      Eugen Krenz's Review Sourced from Google

      Absolute Non-Delivery and Ignorance of Client Needs - Legal Steps Being Taken I rarely write reviews, but my experience with Sumeru Inc. so abysmal that I feel compelled to warn others. I contracted this company for a high-value project, expecting professional and timely delivery as per their promises. What I received was nothing short of a disaster. Non-Delivery: Despite repeated assurances and deadlines, not only was the project delayed, but what was eventually sent was incomplete and of such poor quality that it was entirely unusable. Financial Duress: The sum charged for this project was exorbitant, especially considering that nothing of value was delivered. Payments were demanded under threats of halting the project, which now feels like outright extortion. No Source Code: Contrary to what was agreed upon, no source code files were provided, rendering any potential fixes or improvements impossible. Refund Ignored: Upon confronting them about these issues and asking for a refund, I was met with complete silence. My messages have been ignored, forcing me to take legal action. This has been a costly and time-consuming ordeal. I strongly advise against engaging with Sumeru Inc. Their lack of professionalism, poor execution, and complete disregard for their clients' needs are alarming. I am now in the process of taking legal steps to recover my losses.
