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.

Calibrate Reviews & Testimonials
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)
