      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.

      I had been actively searching for new job opportunities for over three months, often finding that many promising postings were either already filled or closed to applications within 24 to 48 hours of being posted. It was a truly frustrating experience. However, with the invaluable assistance from dotLinkers, everything changed. They were instrumental in helping me establish direct contact with the recruitment team at my future employer. The entire process was incredibly straightforward, and what truly set them apart was their exceptional communication. I was consistently informed about all requirements and received regular, timely updates on the status of my application throughout the entire recruitment journey. This level of care and transparency made a significant difference, turning a previously daunting search into a successful and well-supported experience. I highly recommend dotLinkers for their dedicated support and seamless process.

      Overpriced. Just because they are on top of the Google search doesn't necessarily make them the best. You will get a call from US number, california just to impress you and make you believe that you are working with a sophisticated and hifi company. Have been requesting the backup of my website for ages now, no reply received yet. Dont trust them just like that. If possible visit them and meet them. I am in Bangalore and this address is wrong.
