Mobile App Development Review from Mica Palmer

They helped us solve issues. They designed an app for us.High level/quality of client attention and interaction. All communications, information exchages, and client servicing were well-conceived and well-executed. They kept me on my toes to provide them the information they needed from me. They kept excited about the project and, because of that, kept me optimistic and driving toward the success of my project.The culture of coaching and support they provide start-ups. They don't sleep well unless they know you have all the tools and chops to obtain success. I've never seen any other company provide such rich and valuable deliverables along with ingenious and compassionate client support. Kodevent is a beacon of know-how and wisdom in an otherwise dark ocean for any start-up that is hoping for success.

We needed help designing the Frontend pages on my website. Also some design work. Everyday I would assign my Frontend developer some key tasks and deliverables. He would report back to me. An example of key deliverable he did was help design the logic of flow of grading when we have multiple types of questions. They were quick to respond and professional. They had great professionalism, good talent, and good support.

WordPress Website Design Review from Clea Bierman

Blue Meridian Partners has worked with Constructive as our website design and development partner for more than eight years. During that time, they have played a significant role in shaping our digital presence and helping bring our brand to life online. What I've appreciated most is Constructive's ability to balance creativity with stewardship. They have consistently found thoughtful ways to push our brand forward when innovation was needed, while also respecting and working intelligently within established brand guidelines. Their team understands how to translate complex ideas into engaging digital experiences. Across dozens of projects, I've worked with three different project managers, and each has been highly accountable and genuinely enjoyable to partner with. The relationships have been professional, collaborative, and built on trust. We've also had several occasions where creative projects required significant work on very tight timelines with little notice, and Constructive consistently found a way to deliver. Like any long-term partnership, navigating complex websites and evolving organizational needs requires ongoing communication and attention. What has kept us coming back year after year is Constructive's commitment to partnership, their willingness to solve problems alongside us, and the care they bring to our mission. I am grateful for their contributions to Blue Meridian's growth and would confidently recommend Constructive to organizations looking for a thoughtful, mission-driven digital agency.

Robert Espinoza Former EVP of Policy at PHI

Nonprofits Review from Robert Espinoza

Constructive built PHIs website back in 2017-2018 and, in many ways, they have been with the organization ever since. Over almost eight years, they've grown alongside PHI rather than simply maintaining a site. PHI is a national nonprofit working at the intersection of research, policy, and workforce interventions on the direct care workforce, and a lot of what we do is complicated. Constructive's remarkable team has had a real knack for turning that complexity into something clear, usable, and genuinely engaging online.Some of the things I'm most proud of from our partnership like our worker story gallery, our national resource center on direct care workers, and our online index came out of that collaboration. These weren't just features; they became core parts of how we tell our story and share our work with advocates, policymakers, and practitioners.What made Constructive stand out was how invested they were in our mission. They were creative and technically excellent, yes but more than that, they showed up as a true partner. We didn't experience them as a vendor so much as an extension of our team. I would absolutely recommend them to any nonprofit or social impact organization looking for a thoughtful, dependable digital partner.

Constructive was highly responsive and professional throughout the process, working with us to ensure that every element of the rebranding felt just right.

Flowty is a blockchain-based platform providing various transaction services around NFTs. K-Optional wears many hats in support of Flowty including Front End, Back End, business strategy, SEO and more.The K-Optional team has been incredible to work with. They are proactive, supportive, smart, thoughtful and, most importantly, fit seamlessly into our team and company culture. To put it succinctly, we tried to hire them full-time...and then tried to buy their company to acqui-hire them.Some of their strengths include: reliability, responsiveness and creativity. There are many groups out there that can perform some version of the work we are looking for. There are not many groups that are responsive at all hours of the day, deliver consistently and able to present data-backed business strategies.

With the project manager, we had a short conversation every 2 weeks to clarify all possible questions.We personally love to work in a very process-oriented way. Because when we understand how to do something, we usually know how the end result can look like. With Digis, we also had the feeling that they knew what they were doing and how to do it.

Mobile App Development Review from Tim Nguyen

Warning: Avoid Apptunix (apptunix.com) If you're considering hiring offshore developers, especially from India, I want to share a warning about Apptunix (apptunix.com) and its CEO. My company worked with them on a development project, investing close to $40K, only to have them hold our code hostage and demand more money before releasing it.We entered into the project with clear expectations and milestones, but as we progressed, Apptunix consistently delayed, under-delivered, and eventually refused to hand over the work we had already paid for unless we agreed to pay more. This kind of behavior is nothing short of extortion. It seems like their CEO and leadership are more interested in squeezing money out of clients than delivering quality work.Beyond the financial frustration, the skill level and talent from this team were not up to par. The development work was substandard, full of bugs, and lacked the quality we expected for the investment we made. I strongly urge anyone considering offshore development to do your due diligence or, better yet, reconsider offshore development altogether, as the experience in some regions, particularly India, seems to be in decline.

Ruby on Rails Review from Greg Lipper

In my 30 years in the software business, I have never had as positive an experience with an outsourced development services provider as I have with Altoros. Each Altoros engineer we have worked with has been strong technically, estimated development times accurately, completed projects on time, and delivered code and projects with high quality. Beyond that, they have helped improve our thinking and approach with suggestions and ideas that were better than the spec of instructions we supplied.

Software Development Review from Manfred Olbrich

Stakk has delivered a high-quality product that we are pleased with. Their hybrid model offers great value for money and grants clients to strong technical capacity but also direct contact with management in the UK which really helps with transparency, communication, and ensuring the project is being delivered on thime. The team suggests improvements and meets most deadlines.At the start of the project, I drafted a huge product requirements document that included all the user journeys, my vision for the brand, including the colors and the rest of the brand, and the desired functionalities. I gave this document to Stakk, and they've executed the requirements.
