Unico Connect Reviews & Testimonials
Software Development Review from Jacques Antikadjian
Unico Connect has been an exceptional development partner in helping us build PLCY, our AI governance and runtime policy-enforcement platform. From the beginning, their team took the time to understand not only what we wanted to build, but also the security architecture, governance requirements, workflows, and enterprise use cases behind the product. What impressed me most was their ability to take our security designs and technical workflows and translate them into a functional, scalable platform. PLCY requires much more than traditional software development it involves AI governance, policy enforcement, data protection, model and regional routing, auditability, and enterprise-grade security controls. UnicoConnect approached these requirements thoughtfully and worked closely with us to turn complex concepts into a real product. Their team has been responsive, collaborative, technically capable, and willing to work through difficult architectural and product challenges with us. They have treated the engagement like a true partnership rather than simply a development project. As a founder, it is extremely valuable to have a technology partner that understands the vision while also being able to execute on the details. Unico Connect has played an important role in helping bring PLCY from architecture and security designs into a working AI governance platform. I would highly recommend UnicoConnect to companies building sophisticated SaaS, AI, security, or enterprise software products.
Software Development Review from Daniel Gonsenhauser
Unico built our Order Management System across two operating companies and integrated it with Bringg for dispatch. The hard part wasn't the software, it was the business logic we run on-demand, multi-stop, scheduled contract, and distribution work across multiple markets, and the pricing exceptions that used to live in our people's heads are now configured in the system. Order intake, dispatch, commissions and billing are one flow instead of three, and our team reviews work rather than reconstructing it. What set Unico apart was their willingness to learn how a courier and freight business actually operates instead of fitting us to a template. We worked with a dedicated team on the Unico side - a project lead, developers, and QA with direct access throughout rather than everything routed through an account manager. We've engaged them for phase two.
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.

Simpalm Reviews & Testimonials
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.

I was referred to Esco Logics by a business associate when we were ready to create our very first website. I’m so glad I was connected with this company. Shariq and his team were absolutely EXCELLENT to work with! They brought our vision to life exactly how we imagined it and were always available, responsive, and quick to address any questions or concerns. They were also extremely adaptable to changes along the way. I will gladly recommend Esco Logics to anyone in need of web services and look forward to working with them again.
Tom McGovern's Review Sourced from Google
Hi, my name is Tom, and I’m the owner of Custom Equipment Company. I’ve been in business for over 40 years, and I knew early on that having a strong web presence was essential.I’ve worked with Escologics for more than 15 years, and from day one, they’ve been the perfect partner. I needed a team that truly understood e-commerce—not just the technical side, but also how to create a site that actually sells. Escologics delivered on both.They built a site that’s fast, easy to navigate, and designed to grow with my business. Over the years, they’ve guided me through design updates, new features, and the latest integrations, keeping my site competitive and my customers happy.Anytime I faced a challenge—whether with online sales, security, or user experience—Escologics had the right solution. Their team has consistently gone above and beyond to make sure everything runs smoothly.Looking back, I can’t imagine achieving the same level of success without them. If you’re looking for a partner who truly cares about your business and has the expertise to help it thrive, I can’t recommend Escologics highly enough. They’ve been invaluable to my success.
