Introduce your business and what you do there.
I’m a project manager at an international pharma marketing and digital innovation agency. Our main focus is on the development of 3D technology, augmented virtual reality, mobile apps, among other projects.
What challenges were you trying to address with 4R Soluciones
We just finished a project with them in which they developed the front end and back end of a platform for one of our clients.
What challenges were you trying to address with 4R Soluciones?
We just finished a project with them in which they developed the front end and back end of a platform for one of our clients.
What was the scope of their involvement?
They developed our platform.
What is the team composition?
I’m not completely sure as work directly with the project manager but it should be around five people.
How did you come to work with 4R Soluciones?
They contacted us, I honestly don’t know how they found us, but they were prospecting us for about a year. When a project came up I contacted them and they send a proposal and a budget, we found the price quite accessible. More than anything we really liked how professional their proposal. That made me realize how professional they are and to decide to work with them.
How much have you invested in them?
We invested $3,000 USD
What is the status of this engagement?
We started working with them in November 2019 and we have continued working with them in other projects.
What evidence can you share that demonstrates the impact of the engagement?
I can´t say anything but good things about them. They’re great, very professional, very fast, and their work is flawless. We’ve had great results and it is just great for us to count on suppliers we can trust. Also, they’re based in Argentina, so we are far from each other but despite that, we have been able to work very closely, we don’t even feel the distance.
How did 4R soluciones perform from a project management standpoint?
We haven´t used any specific tools but they are always on time; they sometimes even deliver the projects early. Their project management has been great.
What did you find most impressive about them?
They are great at everything. If I had to pick something, it would be that they are super fast and they know what they are doing.
Are there any areas they could improve?
I couldn’t say anything.

the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
We’re a software development agency, working with our own and with external resources when needed. I’m the general manager.
What challenge were you trying to address with 4R?
We’ve been working with them for more than 10 years and normally outsource with them, especially for projects with the LAMP stack. That’s their area of expertise.
What was the scope of their involvement?
We usually work with them solely for stack projects. In these cases, we do the design, and they work on the development. We also supervise the end results of the products. I know they do mobile developments as well, but we’ve never worked on a mobile project with them.
What is the team composition?
There are four developers involved with us.
How did you come to work with 4R?
We went to Argentina with the intention of finding a partner. While there, we interviewed several companies and chose them.
What is the status of this engagement?
We started working with them around 2004–2005, and the work is ongoing.
What evidence can you share that demonstrates the impact of the engagement?
The results are very good in terms of the price-quality ratio. On the projects we work with them, we take care of the QA as it’s not something they’re specialized in. They deliver quality products on time, meeting our requirements and high standards.
How did 4R perform from a project management standpoint?
We create very simple schedules and try to agree on deadlines that work for all of us. Normally we don’t have any problem with them on that side—they tend to be very precise. As for project management tools, I don’t know what they use internally. We use scrums and sprints.
What did you find most impressive about them?
The communication is great—we have multi-channel communication. We place great trust in them as we’ve been working together for so long. Our relationship with them is excellent.
Are there any areas they could improve?
They could develop more expertize in other stacks, but I understand that there isn’t much on those. It’s an idea that could work for them though.
Do you have any advice for potential customers?
No, I can't think of anything.

the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I currently work as a freelance digital producer for advertising agencies. For the last five years, I’ve specialized in platform development. Now I work in project management and UI/UX platform design.
What challenge were you trying to address with 4r Soluciones?
My last project with them was at the studio where I used to work. We designed an apartment rental platform for an important real estate company. This company mainly rents apartments to traveling businessmen, and have several buildings in Buenos Aires and other countries. We designed the platform, and they implemented it using a challenging tool called Airtable.
What was the scope of their involvement?
They used a lot of different technologies to build this web platform. They used frontend technologies like HTML and JavaScript for animation and used PHP to connect with Airtable. They also worked with the Airtable code, since it was the structure of the database.
What is the team composition?
It was a team of four throughout the project: three developers and the project manager.
How did you come to work with 4r Soluciones?
I met them in 2010, when they were working for an agency where I also worked. We had a project together, and I liked it. Since then, I’ve had a constant relationship with them across all the agencies and studios where I’ve worked.
What is the status of this engagement?
It started at the beginning of 2017, was implemented in varying phases, and ended at the beginning of 2018.
What evidence can you share that demonstrates the impact of the engagement?
They are committed and dedicated to their projects. Software development is sometimes unpredictable. I have plenty of experience with this kind of project, and you never know how they'll turn out. No matter the setbacks, they are constantly committed to the project. I enjoy working with their team because they deliver great results on every project.
How did 4r Soluciones perform from a project management standpoint?
They're always reachable, and our communication is great. They’re open to adapting to my methodology and collaborating on any element of the project.
What did you find most impressive about them?
I’m most impressed by their commitment and their teamwork capabilities. They are very well-versed in development, and can solve almost any problem I give them.

Please describe your company and your position there.
I'm the Technical Director of an agency that does work for a number of clients from small to large.
For what projects/services did your company hire Crombie, and what were your goals?
We hired Crombie to help us create a front-end heavy website in a tight timeline. This project made use of advanced scroll effect features on top of WordPress and ACF.
How did you select this vendor and what were the deciding factors?
We had reached out to Crombie before as a potential partner after finding them on Clutch, and had identified this project as a good chance for us to work together.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
We had a kick-off meeting to show off the comps and animation details. We made use Slack for communication, Bitbucket for the code repo, Invision and Sketch for the designs, and WordPress, Wow.js, and Scroll Magic for the codebase.
How many people from the vendor's team worked with you, and what were their positions?
We worked with an account manager and a developer directly on Slack and in Zoom calls.
Can you share any measurable outcomes of the project or general feedback about the deliverables?
We were able to drive the project to a succesful completion. We had struggles due to the complexity of the front-end experience which caused us to have to revisit our designs and make major changes. Crombie was responsive and supportive through all of our requests.
Describe their project management style, including communication tools and timeliness.
We had Zoom calls twice a week or as needed, and communicated on Slack as well. We had an initial deadline, which Crombie helped us hit, and we maintained ongoing work beyond that initial launch for further tweaks and work on the site.
What did you find most impressive or unique about this company?
They had existing knowledge of scroll-based experiences using Scroll Magic, and they were incredibly flexible with our variety of changes throughout the execution.
Are there any areas for improvement or something they could have done differently?
We could've used more help in the scroll effects / motion / animation - getting the 'feel' just right. This was expertise that we were missing ourselves, and could have helped us out on the project. I don't believe this was a shortcoming of Crombie as much as our own lack of experience in creating such involved/advanced experiences previously.
