Software Development Review from Ryan Husk
HatchWorks developed a solution to automate calculations for our sales team. The company created an application with a user-friendly interface and scalable algorithms in Python. HatchWorks had similar experience in the healthcare industry and we were satisfied with their responsiveness, QA, communication, and ability to translate imagination into actionable tasks. The project was well-organized with clear expectations and deliverables, making it easy to address miscommunication.
Software Development Review from Shaun Bank
HatchWorks was hired to develop custom software for a hybrid app and rebuilt the front-end. They provided top talent in LATAM and adapted to end client's changing needs. Despite rate fluctuation, they performed well, met commitments, received positive feedback and maintained high level of quality output and professionalism. The team coordinated effectively and the nearshore model is becoming more popular. The consulting firm was happy with HatchWorks' velocity and code quality.
Digital Strategy Review from Meishelle Haverkamp
HatchWorks is always a true partner that consistently delivered results. They completed several market analysis projects for us analyzing the competitive landscape and provided recommendations for strategic growth and growth opportunities. We have a long-standing relationship with Hatchworks. They have done several market analysis projects for us & always are able to synthesize large amounts of data into a compelling & easy to understand story.

Web Development Review from Shifa Sutar
We had a great experience working with Unico team for our Google Workspace migration and account setup. The entire process was smooth and well-managed. The team was extremely supportive, responsive, and guided us at every step, making what could have been a complex transition feel effortless. Highly recommend their services.
Website Redesign Review from Heta Patel
We engaged with Unico for website design and front-end coding for the same. It was a good experience overall. Initially we faced some issues which were resolved and the team mates for coding were great, had good knowledge and were able to deliver as per our expectations.
Web Development Review from Hrishabh Sanghvi
We have been working with Unico for over 5 years now. Very happy with their services and responsiveness. They are very customer-centric in their approach. We moved away from a larger firm to Unico, since this mid-size has a very cooperative engagement which worked well for us. Recommend them to anyone in Seed to Series B stage.

UI/UX Design Review from Audrey Thomas
Highland is a great partner. The sought to deeply understand our product, customers, and pain points and built a number of forward looking opportunities for us in addition to the tight scope of our project. Proactive, thoughtful, responsive, and flexible. We are a small team and found lots of value in working with Highland to get our UX refresh project up and running.
UI/UX Design Review from ✨ Liz Pisney ✨
We recently partnered with Highland on research and prototypes for a new information architecture on a volunteer resources site for our Chapter leaders. Having over 3000 volunteers around the globe can introduce a lot of nuance and complexity to research and design processes. The team at Highland handled it all skillfully - focusing on how to deliver the most clarity and usability to our audience. 10 out of 10, I would recommend working with the Highland team!
Webflow Review from Lee Wiensch, CAE, CFRE
We had a great experience working with the team at Highland to develop a new website for the Thoracic Surgery Foundation, a charitable organization aimed at advancing heart and lung health for all. Highland worked with us to re-imagine a dated website with limited functionality, and developed a a gorgeous new site that beautifully reflects the vitality of the organization. We anticipate that our award applicants, donors, surgeons and grateful patients will be able to easily navigate the new site and have a much-improved user experience. Jeff Blanchard and his team were exceptionally good listeners, and worked hard to create solutions for our complicated awards program. They provided good training to our team throughout the process so that we have been able to keep things updated and easily make changes now that the site has launched. I am grateful for their patience and very quick turnaround as we juggled a new strategic plan and new branding, all at the time of the website creation. I have been continually impressed with the expertise and the innovation that Highland brings to a project like ours. It was a pleasure to launch this site -- on time and on budget -- with their excellent work and support.

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.
Liam Durbin's Review Sourced from Google
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.
Dave Reynolds's Review Sourced from Google
I've been with Flexsin for 3 years now, and it's a great place to work. Talented technical staff and good management. After years of providing IT staffing solutions for US based companies with local personnel, I'm now able to save our clients a LOT of money by using the resources of our talented team of resources at our offshore development center instead.
