Why Our customers trust us

Our clients speak

Our aim is to reach customer satisfaction. Explore some of our clients’ testimonials to learn the results of our productive collaboration.

I have never worked with a more efficient, corporative, and skilled programming team.

I have never worked with a more efficient, corporative, and skilled programming team as Altoros. They consistently met every target set for them, usually ahead of their own estimates. In addition to providing very skilled labor, they consistently sought to offer their skilled knowledge in project management, software development processes, and system test. I would definitely recommend them to anyone requiring enterprise database application design and development.

Senior Systems Architect

Altoros helped us double our customer base and roll out several new product lines.

We had experience with Altoros on a previous project, and when it came to resourcing at Revere we looked to Altoros for the experience and flexibility we needed. In collaboration with our in-house team, our Altoros contractors swiftly identified and articulated critical paths against our roadmap. Altoros contractors were able to dive in from day one and meaningfully contribute to our engineering organization.

Alex Scott, Co-founder at Revere

Altoros eliminated 95% of service breakdowns.

The remit of the Altoros ops folks is to locate and stabilize a malfunctioning service and report it to the engineering team. If they can't stabilize it they have permission to wake us up, but that's only happened once.

Laurie Voss, Co-Founder and COO, npm

Communication and issue escalation are both prompt.

Altoros has taken full responsibility and effectively utilized project management methodologies since day one. Communication and issue escalation are both prompt, while a proactive approach and near-constant availability continue to impress. Their team even works overtime to ensure timely delivery.

Christoph Mussenbrock, CEO at Etherisc

We received a software system of a high production.

Working with Altoros we were able to build a software system of a high production with an optimized delivery, which is able to take orders, and predict inventory with more efficiency and speed. We were able to integrate data from their off-the-shelf solutions and additionally build tools that were not previously available. I would say that together Altoros and I were able to achieve a happy client, a more efficient product delivery system, and a scalable platform for the future.

Nolan Zandi, Founder and lead solution architect/engineer at Zanobo partners

Altoros is a great choice specifically for software development projects!

For software development projects, specifically, web development and even some non-standard projects, I think Altoros is a great choice. Their ability to quickly provide high-quality resources, multiple geographies, and flexibility has been a huge asset for us. For example, I do not think I would be able to ask any other software vendors to draft a resource in France for three months. I asked Altoros about Altoros and there were no hesitations. I completely recommend Altoros.

Paul Caponetti, Director of engineering at Xively by LogMeln

The code quality, as well as, communication are top notch.

I would definitely recommend Altoros for software development projects. It has been a pleasure working with them. We had issues where we had problems over the weekend and if something happens on Saturday and these guys come in and take care of it. There is a huge commitment from the team. The code quality is top notch and communication is top notch. Absolutely would recommend hiring Altoros for software needs.

Landon Swan, Co-founder of Likefolio

We got immediate and acute development help from Altoros.

We needed immediate and acute development help, and we needed people who knew how to lite JavaScript front-end code and modify our existing product. We got the software done with Altoros lots sooner than we would have done with all our internal resources and we got the additions and modifications to our product that we wanted in time basically.

Kalle A. Ojala, Chief product officer at Mediasapiens Ltd.

Great job! We highly recommend Altoros.

We highly recommend Altoros to rapidly build complex applications using cutting edge technologies. Again, great job!

Christopher Adorna, User experience consultant at Sony (LA)

I would absolutely recommend Altoros for anyone looking for great engineers.

It’s a very laid- back, but very professional company at the same time. Being able to work with people that understand technology, but also understand what it means to run a company is great. I would absolutely recommend Altoros!

Nicolas Cormier, COO at Pexip

I’m happy with the partnership between Trace Data and Altoros!

By partnering with Altoros, I hired engineers much faster than I could hire in the Bay Area. As my engineering team is growing, I can continue to rely on Altoros to bring new engineers quickly. Altoros charges a reasonable price, definitely lower than the Bay Area. This helps me to achieve my goal within budget. Based on past year’s experience, I’m happy with the partnership between Tracedata and Altoros, and would recommend Altoros, for sure.
