Zarego provided our team with excellent development and design resources for website and mobile applications. For web development, they helped build websites from the ground up using different cutting edge technologies and were excellent at DevOps, Analytics, Integration and SEO optimization. The Zarego team also helped us build Android and iOS applications that were deployed in Google Play and Apple Stores. The mobile apps were user friendly and implemented app security measures, optimized for app performance and easily integrated with other systems for automated data flow. All products that Zarego helped us create had user-friendly user experience and user interface designs. Their team was professional, communicative, friendly and excellent at client presentations.

Successful mobile and web applications deployed in a timely manner.

They often delivered ahead of time and were responsive in a timely manner.

Their developers occasionally surpass our senior developers in speed. They are a pleasure to work with and are very adaptable when given feedback.

There's nothing they need to improve on.

I’m the CEO of Kendall Development, an SEO and web design services company.

We needed to develop an AI tool for a pharmacy chain.

Zarego developed an entire app for an AI skin care specialist that can give recommendations and routines based on customer input in the software. This is a mobile, tablet, and web app that was constructed to establish the foundation of something bigger, where this AI skin care specialist will also be able to recommend other products in the future. The app handles a very large database of multi-set products, pricing, product descriptions, and many other things. It combines this with the user input to provide a final result with a skin care routine tailored for the client’s needs and budget.

We worked with 2–5 teammates from Zarego.

We found them on LinkedIn. We chose them because they were close to our geographic location, their pricing fit our budget, they had a great culture fit, they offered good value for the cost, and their company values aligned with ours.

We worked together from October 2025 to June 2026.

They’ve provided deliverables on time every time. We haven’t deployed the app to the public yet, but we’re testing it internally in our company and with VIP customers. The app performs smoothly, with no lag, glitches, or issues. It’s currently measuring everything without problems.

They delivered what they promised, and they overdelivered. They’ve delivered the project before the expected time. We communicate via virtual meetings.

Their work ethic and friendliness are impressive. They’re also able to explain really technical stuff in a way that a 7-year-old can understand.

No, they should keep doing what they’re doing.

I’m the founder of RedTech, a solutions development company for agricultural companies. We usually work in Brazil, developing systems for fruit dealers.

We wanted to develop an AI-based platform. We had used chatbots based on traditional software, but we wanted to build our own platform to handle our data and knowledge base.

Zarego has developed a private platform for us based on a domain-restricted large language model (LLM). The team has used software like N8N and APIs for LLMs like OpenAI and ChatGPT with robust guardrails. The platform also incorporates a retrieved argument generation (RAG) to handle language better.

We’ve worked with Matias, who has been our project manager, a solution architect, and a full-stack developer.

We found Zarego on LinkedIn. We saw their advertisements and how deeply they went into their explanations. We also found some projects they had developed on LinkedIn.

We’ve invested around $10,000. Based on some deliverables our customers are asking for, we estimate we'll spend $25,000.

We started working together in May 2025, and the engagement is ongoing.

We’re very confident and happy with Zarego’s work. We’re doing an excellent job, and we plan to continue working with them. We’ve sent a beta test for some key accounts, but we don’t have KPIs yet. We plan to measure how many salespeople among our customers will use the platform.

Zarego meets deadlines and stays on budget. We communicate via WhatsApp, Google Meet, and Microsoft Teams.

Zarego’s technical background is impressive. AI is very dynamic, and every day there’s some news. I’ve just finished an MBA in AI project management, and Zarego always sends me news I’m not familiar with. The team is very engaged with what’s happening in this dynamic world.

We need more documentation. As we’re developing, we have more conversations and presentations, but we need documentation.

A US-based startup hired us to develop an MVP for a web platform that allows users to search and interact with 3D models, such as car engine parts and anatomy components. To accomplish this, we needed to build a dedicated software development team, including a senior JavaScript developer and an expert in HTML and CSS. Zarego played a crucial role by helping us source and place the talent we needed to complete our team and successfully deliver the project.

We delivered the features the end client needed on time and within budget.

They provided consistent support and maintained regular follow-ups.

I was impressed with their great talent, shared values, and willingness to learn.

At times, the talent they provided struggled to set clear expectations.

The project involves several key technical developments and configurations aimed at improving system integration, automation, and monitoring. Below is a breakdown of the main tasks and deliverables.

The project progressed based on monthly objectives, where tasks were estimated in terms of hours and focused on clear, binary outcomes (either the goal was achieved or not). Success was measured by completing key tasks within the allotted time and fulfilling the expected functionality.

The project management approach was well-structured, with monthly objectives and estimated hours for each task. Progress was also reviewed on a weekly basis, allowing for adjustments when necessary. If any deviations occurred, the team quickly coordinated new priorities and actions to stay on track.

What I found most impressive about the company was the depth of knowledge and expertise demonstrated by the management team. Their ability to navigate complex project requirements and adapt strategies effectively, even under challenging conditions. The management’s approach to regular progress reviews and their capability to quickly address issues showed a high level of proficiency and strategic insight.

One area for improvement would be better alignment with time estimates. There were instances where the project didn’t fully match the original estimates. Improving the accuracy of these estimates and monitoring progress more closely could help manage expectations and reduce delays.
