Software Development Review from Dan Adika
Infograins has helped us develop our custom software system. Before we signed the contract, we had initial pre-sales meetings, during which I provided them with documentation. We also signed an NDA so that they could look at everything I provided. Then, Infograins came back with an in-depth project proposal of about 50 pages and we signed the contract. As for the technology stack, we're using React.js, Python, and Django to create this software piece. Moreover, our whole backend is hosted in AWS. We're very happy and satisfied with how everything has turned out and with the whole Infograins team. Their willingness to discuss issues, fix problems, and help us with anything we need is great, so I wouldn't want to have developed this product, especially the MVP with anyone else. I can't think of anything Infograins could change. Going forward with other projects, we might find some improvements. Thus far, we're very happy with them

Web Development Review from Malcolm Gibson
The business supplied an extraordinary front-end for our cybersecurity web application combining looks with capability. They showed a deep understanding of our market while crafting a user-friendly and straightforward user interface that lines up with our brand name along with security-focused requirements. The Calibrate team was very receptive to comments while recommending cutting-edge style options that improved the users experience. Their focus on detail, sticking to timelines, and dedication to quality made the whole project run smoothly and efficently. We are incredibly pleased with the end product which has actually gotten favorable comments from our customers plus end-users.
Mobile App Development Review from Sony Tiwari
The whole Team at Calibrate have been great from beginning to end, and we're excited to have a partner as we continue to grow. Three words I would use to describe Calibrate are organized, insightful and collaborative. From the outset the scope of work was clearly defined, but they also showed great flexibility working through changes that arose. Faizan is terrific at running our regular meetings and keeping everyone up to date on progress. The team has a good balance at listening to your ideas but also guiding with their experience and expertise.Our project took longer than anticipated because of issues unearthed during the development, but Kevin and the team worked through it all with us. They went above and beyond to make sure we were satisfied with the final outcome.This is a talented team for sure, but their passion and ability to collaborate effectively is what really sets Calibrate apart.
eCommerce Development Review from Lorien Yonker
I partnered with Calibrate to develop a new eCommerce website, expertly integrating it with Shopify. Its guidance on software operation and website maintenance for future collections was invaluable. I valued the agency's patience and helpfulness in teaching me software intricacies and quick adaptability to changing project scopes. What set Calibrate apart was its attentive approach. Calibrate's small team was ideal for addressing my concerns proactively. While some may find it a drawback, I preferred the agency's primarily virtual meeting approach. (Verified via email)

UI/UX Design Review from Joe Anandarajah
We partnered with HyperSense through their TechBoost program, and they truly impressed us with their deep understanding of our business needs. They provided invaluable support with our marketing, website, and product UI/UX, which has resulted in significant traction with both customers and investors. As we continue to grow and develop our product, we look forward to working with them again. The HyperSense team is highly skilled, reliable, and trustworthy. We highly recommend their services.
UI/UX Design Review from Ele Munjeli
My experience with Hypersense came through their Techboost program for startups. I needed help to design a very complex UI/UX for a website dedicated to planning farm operations with agricultural robotics and other advanced networked devices. While I spent a considerable amount of time in the field gathering requirements, I felt overwhelmed by the implications of designing for such a complicated scenario. Hypersense came to the rescue and delivered a beautiful UI with a clear path for the users (farmers) to explore and develop advanced automation across crops and seasons. It took a lot less time than I expected; the team was engaged and asked all the right questions from the get go. That made it easy to let go and trust the pros at the agency with design decisions. As an engineer, I am one to have my hands on every part of my work, but in this case, I found, to my relief, I could just say: do what you think is best. As a result I learned a lot about my own application. The team did not just design wireframes - they designed elegant interactions and workflows that made sense. The UI prototype was styled as well, and the team provided terrific advice on how to upgrade the existing styles for my applications to give them better web appeal and usability. The resulting design is expressive, engaging and inspired. Hypersense provides service that was more than professional - it was personal. I came away from the work with a better sense of what I am building, how to build it, and how the application will be used. I highly recommend Hypersense and will work with them again whenever I have the opportunity.
Cross-Platform Review from Jessica Queen
HyperSense developed a command dashboard for a new wireless medical monitoring device Omedus is creating. Their professionalism and dedication to the project were wonderful. The figma demo they created exceeded our expectations and we have had significant increase in product interest after using their demo with our customers. Omedus would absolutely recommend them for other companies and we plan to continue to engage their services for our own.

Jigna was professional, patient, responsive, and highly collaborative throughout our CHOKOPAM branding project.

1 2's Review Sourced from Google
We hired flexsin technologies to build software for us in July 2022. They agreed to sign NDAs and all relevant paperwork. They prepared the NDA as they preferred it and sent it to us for review and signature. We reviewed the NDA and changed the Jurisdiction to UK and sent it back to them for a signature which they delayed in signing up to date. After they reviewed everything, they gave us an estimation of USD 17,000. They sent us a contract with upper price cap stating that any extra activities and costs incurred above the agreed upper price cap will be their responsibility and we as the client will have to pay nothing extra. They estimated the project will take 12-14 weeks. They started the project and assured us the NDA and Contract is getting sorted and they will send it over as soon as. Long story short flexsin Technology never honoured the contract and the price cap as the price started increasing past the price cap. It is now been 8 months since they started the project and they have not signed the NDA nor the Contract as agreed. We noticed they misspelt the names on the NDA and Contract. We asked them to rectify the spelling mistakes and they have refused asking us to Change the NDA that they wrote themselves to meet their interests. They are asking us to include on the NDA that UPwork will resolve disputes in relation to incorrect spellings on the paperwork and the NDA as if they are planning to make more mistakes. Up work is just a platform that brings developers and clients together, UPwork does not resolve spelling mistakes and unsigned paperwork. UPwork is NOT developing our software for us, we did NOT share the software information with UPwork, we shared information with Flexsins Technologies and above all Up work did NOT misspell or fail to sign the NDA or Contract, that was Flexsins Technologies mistakes to fix and NOT UPwork mistakes to fix. They are now asking to write another contract for more money probably with another price cap just to lure. They have agreed to send the assets back to us immediately. Updates of this review to follow on here, twitter, LinkedIn, IG, TikTok, and any other platform.

I have had a great experience with Flexsin. My small business is a bit of a niche (horse racing) but the team at Flexsin worked very hard to understand the nuances. Very impressive breadth of skills on the team. The support work they do for my small business on a monthly retainer has been good, as has their project work on a mobile app.
