Mobile App Development Review from Guiulianna Cespedes
Our company needed an Android app that could support a mental health platform in a way that felt calm, easy to use, and dependable for daily users. We hired Simpalm to build that product in Kotlin and help us move from concept into something real customers could use. For us, trust and simplicity mattered more than packing in too many features.They took a fairly hands-on role, which was helpful because we were still making product decisions as the project moved. Some weeks I was deeply involved reviewing screens, and other weeks they pushed things forward on their own. That balance worked well. They would usually come back with two or three options instead of just asking what we wanted.We did hit one rough patch around notifications where the first version didn’t behave the way we expected, so that had to be revisited. They fixed it without making the process difficult.The finished app runs smoothly, feels organized, and gave us a much stronger mobile presence on Android. Most importantly, early users found it approachable rather than overwhelming, which was exactly what we wanted.
Mobile App Development Review from Amanda Chalofsky
My experience with Simpalm was very good. They made a full prototype of our neuro-wellness app so we could show partners and investors what our system looks like. It matched our brand and showed the flow in a simple way. Their communication was steady, they stayed on time, and they explained things clearly. The prototype helped people understand our idea fast, and it moved our project forward. I felt supported the whole time.
Mobile App Development Review from Matt Rudnick
Working with Simpalm has been a really positive experience. We hired them to handle the frontend development of our mobile app for iOS and Android, while our backend was already in place. From the start, their team communicated clearly, stayed organized, and met every deadline we set. They were flexible when we added new features, and their designer’s input really helped improve the look and usability of the app. I appreciated how reliable and easy they were to work with having a U.S.-based team made communication smooth and fast.

As a growing business in Australia, our internal systems had become difficult to manage. We partnered with SDLC CORP for Odoo development, and their team took the time to understand our workflows and bottlenecks.

Ruby on Rails Review from Michael Peter Craies
Rubyroid Labs joined our team at a time when we were starved for Ruby on Rails devs. After a very short while, the assigned team members were taking on more and more complex code and helped bolster our development outputs. Before they joined us, our average bug response time was over 2 weeks, a value that they have helped us reduce to under 8 days, with urgent tickets being resolved within a few hours. There teams' response times regarding staff movements (e.g. replacing one of our assigned devs) as well as our queries are impressive. I would definitely recommend them to any company looking to outsource their development needs.
Software Development Review from Anonymous

Software Development Review from Theodore Patestos
We’ve worked with Saad and his team for close to a year now. They’ve been diligent throughout the process, responsive and communicative. They came in mid-stream to save the project from another development team that didn’t live up to their commitments. I would highly recommend Plego to any company looking to see things move forward on a stalled project or looking for a team that will jump in and start to get things done.
Web Development Review from Tyler Tomlinson
Saad and his team were a great group of people to work with. Our scenario was probably unique to this group, and they tackled the project with a full head of steam and with no hesitation. It has been a pleasure working alongside his team.

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.

I had the pleasure of working with Debut Infotech for DeFi development, and I am extremely satisfied with their expertise and service. Their team utilized a comprehensive suite of tools, including smart contract generators, DeFi protocol integrators, and liquidity pool management tools, all of which streamlined the development process. They not only helped us build secure and scalable decentralized finance solutions, but also provided automated yield farming and staking platforms that significantly boosted user engagement. Their focus on security, with built-in auditing tools, gave me confidence throughout the project. I highly recommend Debut Infotech to anyone looking for reliable, efficient, and innovative DeFi development.
