      The dashboard Perimattic delivered is minimal, well-structured, and very user-friendly. Small touches like the layout, flow, and clarity of controls make a big difference. Great work by Gaurav and his team.

      Bala Krishnan's Review Sourced from Google

      I have been working with Technotackle since 2015, and it has been a wonderful place to work and grow professionally. The company provides a great environment to learn new technologies and gain valuable experience. One of the best things about Technotackle is the supportive leadership and team culture. BalaVishnu has been very encouraging and helpful, always guiding the team to improve our skills and deliver better results. I’m grateful for the opportunities and knowledge I’ve gained here over the years. It’s a great place for anyone who wants to build their career and continuously learn.

      Rudresh Jayaram's Review Sourced from Google

      I’ve been working with Techno Tackle as a publishing consultant for their upcoming books, and the experience has been nothing short of exceptional. There are so many things Techno Tackle does brilliantly, truly 11 out of 10. Their communication is clear and thoughtful, tasks are completed efficiently, and working with them feels genuinely freeing. Ideas and suggestions are not just heard but deeply respected and appreciated. There is complete freedom in the way work is handled. There is no micromanagement. Responsibility is clearly defined and trusted. This clarity in communication and ownership makes the entire process simple, smooth, and stress free. One thing that stands out strongly is professionalism. Payments are always on time, often even before the deadline. That level of integrity builds immense trust and confidence. I have also had conversations with a few team members, and hearing about the company culture feels almost unreal. The happiness, contentment, and work life balance they experience are rare and inspiring. It truly feels like an out of the world experience to hear how aligned and fulfilled people feel working at Techno Tackle. I am genuinely excited to be part of this book journey as a publishing consultant, and much of what I am experiencing traces back to the foundation built by Bala Vishnu. He has been a phenomenal founder and the driving force behind this culture, clarity, and excellence. I am deeply grateful for this opportunity. More power to Bala. He is setting a powerful example, and I am certain he will inspire many entrepreneurs in the years to come.
