      Amidst a considerable range of vendors that took part in the official RFP process, Apptension stood out. Its proposal resonated seamlessly with Cannabis Company's prerequisites, leading the client to entrust their project to Apptension's proficient team of front-end developers. The objective was to develop a front-end solution for an internal business management tool, and the client is optimistic about the journey ahead with Apptension.

      Software Development Review from Sinead Catney

      The Mill asked Apptension to create a CMS that manages the client's app and website. The CMS handles diverse app components, including a huge gallery, localized content, and interactive user-focused copy. The product boasts eight engaging challenges and rewards, interactive gameplay, and a shareable filter. The platform integrates dynamic gallery and text elements, all managed through the CMS. Through the agency's ongoing maintenance support, the collaboration was extended. (Verified via email)

      eCommerce Development Review from Lukas Szabo

      The project involved redesigning the website for an internationally acclaimed and award-winning wine producer. Key deliverables included modernizing the website, integrating e-commerce, connecting it with the accounting system, and enhancing the user experience. Our specific requests for the project include: - Modernize clients website - Easy to manage content - Easy to manage online store products - Implementation of ecommerce - Integration of the ecommerce shop with clients accounting system Following the successful completion of the project, our client saw a substantial improvement in business performance. The outcomes achieved include: - A 75% increase in the number of visitors - A 25% increase in overall revenue - A 100% increase in online revenue - The launch of online sales for additional merchandise The project was managed by a project manager with the support of two team members. We utilized Basecamp for project management and communicated via email and phone. The project was delivered on schedule, with all requirements meticulously implemented. The vendor diligently adhered to all specifications, and the QA team ensured that everything met the requested standards. We were highly satisfied with the project's management and delivery. We would definitely recommend them and look forward to collaborating again in the future. Their processes are transparent, and their communication is highly professional. They demonstrated flexibility in both pricing and delivery. Additionally, they provide post-launch services, including website maintenance and growth support. Their client care, communication, and development standards are exceptional, and we hope they continue to maintain this high level of quality.

      Web Development Review from Kent Fenwick

      Certainly! Here's the revised review with the project timeline adjusted to 2017: We had the pleasure of working with Xfive back in 2017 on a project to build a microsite for a new product launch, and we couldn't have been happier with the results. Xfive demonstrated exceptional expertise and professionalism throughout the entire process. From the outset, their team understood our vision and requirements perfectly. They built a fantastic microsite that not only met but exceeded our expectations. The design was sleek, user-friendly, and tailored to our brand's identity. Their technical skills were evident in the smooth functionality and responsiveness of the site. We highly recommend Xfive to anyone looking for top-notch web development services. Their team's dedication, skill, and professionalism are truly commendable. We look forward to working with them again on future projects.

      Web Development Review from Anders Östlund

      CleverCrew is great to work with. I have known the company for four years now and worked together for a year and a half. My favorite is that you can tell them to fix anything, and they will. Not these closed boxes with specialities that have become common among certain developers but instead open minds and a "fix-it, and make it work" attitude.

      Mobile App Development Review from Brigitte Granger

      CleverCrew was recommended to me by a fellow entrepreneur, and I'm so glad I took their advice. Over the course of building my startup, I worked with at least 10 other developers and agencies, but none came close to the professionalism, experience, skill, and friendliness that CleverCrew brought to the table. The lead developer Tonya was outstanding. She balanced understanding our needs with offering thoughtful recommendations to improve the project. Her communication was excellent, and despite major time zone differences, she ensured we were always aligned and informed at every stage. She also demonstrated strong leadership, managing her team with precision and proactively addressing any issues or questions. We ultimately had to make the difficult decision to shut down company. However, having CleverCrew by our side during this challenging time made the process far less painful. Tonya's support and guidance throughout the closure were invaluable, ensuring everything was wrapped up professionally and efficiently. For anyone looking for a reliable, skilled, and collaborative software development partner - especially a bootstrapped startup - I couldn't recommend CleverCrew more. They set the bar for what a development team should be, and I'm grateful for their role in both building and gracefully guiding me through the closure of our mobile app project. I look forward to working with them again in the future!

      We worked with What the Flutter previously, and had a great experience. The team is very productive and solutions-oriented. What we liked the most is their view of strategic solutions. Instead of simply getting the project done, they helped us find the best way to accomplish tasks and find alternatives to consider. Their communication and the output of the developers was great. This is exactly what we're looking for in our partners.

      I had the opportunity to work with REBEL on behalf of the student government, and I highly recommend them! Communication with the company is seamless. The graphics for the embroidered sweatshirts were meticulously crafted, in accordance with all our suggestions. The sweatshirts are of very high quality and have beautiful colors. Both students and faculty were very pleased after seeing the sweatshirts in person (so much so that we had to order a few more – which REBEL produced and delivered promptly 😀). I highly recommend them!
