      Issac John Ex-Business Head, Discovery Plus at Discovery India

      Wearables Review from Issac John

      A global OTT provider - Discovery+ earlier this year, had a breakthrough launch in a cluttered OTT market like India with a differentiated product targeted at lifelong learners and passionate communities. The team at Robosoft played a significant role in building this multi-platform experience spanning iOS, Android, Web and Fire TVs. Their team comprises an extremely dedicated bunch of folks with a keen problem solving approach and under the stellar leadership of Ravi Teja, Jay Shah, Srinidhi Rao and Pooja Bal, they have been the kind of dependable partners that a lot of brands would be fortunate to have. I wish them and their team the best for their future.

      Mobile App Development Review from Deepak Porayath

      Our experience working with Robosoft has been quite good in terms of product and outcomes. With our CapitaStar@Work app for India business, the end goal was to bring our customers and their employees onto a digital platform. The objective was to integrate our solutions such as visitor, parking, and ticketing system management into a single app. CapitaStar@Work caters to our requirements and surely will make life simpler for our users. I would recommend Robosoft to others because it is a good organization to implement technological interventions in any traditional manufacturing, real estate, or brick-and-mortar industry.

      Web Design Review from Katharine Mason

      David at Boomcycle is professional and responsive. When we were recently hacked, David helped us to restore all our website features, and he even provided us with information to help us to identify how we may have been hacked. I recommend Boomcycle; they care for their clients and are very helpful.

      Eric Barnett's Review Sourced from Google

      I've had the opportunity to work with many agencies over the years; Boomcycle Digital Marketing stands in a league of its own. From sharp, modern web designs, to real SEO expertise that visibly moves the needle for search rankings. They also educated me as to techniques to make sure AI searches show up in ChatGPT that I wasn't aware of. They are knowledgeable, communicative, and genuinely invested in client success.

      Peggy McCabe's Review Sourced from Google

      ISBX is a very professional and talented web development company. The overall experience I had with them in the redesign of our website was outstanding. They were extremely creative, provided viable options at all junctures, and delivered on time and on budget. ISBX also provided a very hands-on, and professional team who understood our need for brand engagement and outreach to a new audience with our website refresh. The team also optimized the new site for mobile usage which was very important to us. ISBX successfully executed our complex project efficiently, with excellent communication and attention to detail at every step. I wouldn't hesitate to work with them again.

      ISBX helped us from concept to launch without any issues. They were communicative, patient, and able to quickly implement solutions to project changes that came up along the way. We appreciate that they took the time to hold our hands with explanations and detailed questions to make the process as stress free as possible and to get a good understanding of our product.

      I've been a client of ISBX for nearly three years. They are hands down the best development firm I have ever worked with. They are on budget and on time consistently. They are trustworthy, highly communicative, and very versatile. Nothing is in the "too hard box" for them.
