We help our clients solve problems by either building products from scratch using our agile teams, augmenting the client's existing teams, or simply providing consultation and discovery if they only have an idea but no implementation plan.
If we are developing a product from the beginning. We put together the right team by understanding your needs and budget. Agile and scalable teams are able to manage requirements and changes in real-time. These teams can immediately start delivering technology solutions since they are quickly formed to implement and execute upon sprint plans.
Helping with Staff augmentation means you get to choose the best talent for a specific project. Since clients are usually involved in the vetting process, these are high-profile developers that go through several interviews and test challenges.
And finally, Crombie can help in the Discovery phase by doing consultancy work: The team is formed by technical profiles, such as CTOs, Tech Leaders, and Business Analysts. They will validate existing assumptions and avoid using false premises. This is how you gain important insights into the best way to structure and design any product idea from a technical and user standpoint. Also, we advise choosing the most appropriate minimum viable features to launch the beta version, and potentially scale it.

Mobile App Dev Staff Augmentation for Innovation Company
the project
“Crombie’s communication and responsiveness are excellent, and they have really knowledgeable staff working for them.”
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’m the VP of Innovation at Phiquest, an innovation company. We help early-stage entrepreneurs develop their idea, business policies, and procedures and bring them to an MVP stage.
What challenge were you trying to address with Crombie?
We needed to augment our staff for mobile app development.
What was the scope of their involvement?
Crombie provided us with a developer to support a blockchain-related mobile app development project we were working on. Before engaging with them, we were working with a different development team, but our engagement didn’t go well. Thus, when they joined, we explained our end goal and what we had thus far, and they essentially brought the project across the finish line for us. To develop this product, we used Laravel as the main technology stack, and we built it for iOS and Android.
What is the team composition?
We worked mainly with a project manager and a developer. Still, at one point, we had two people from Crombie working on the app.
How did you come to work with Crombie?
We found them through a mutual contact.
What is the status of this engagement?
We started working together around April 2021, and the project ended in June 2022. However, we plan to use them again in the future.
What evidence can you share that demonstrates the impact of the engagement?
Thanks to the app built by Crombie, our client is now moving into a pilot stage. The app currently has 30 users using it, but those numbers aren’t a reflection of its success yet because the app is still unpublished. As for the quality of the app, it is very stable, and those users seem to be enjoying it. So far, the reviews have been very positive.
How did Crombie perform from a project management standpoint?
Crombie’s project management was excellent; I can’t say enough good things about that. We used ShareTable and Google Drive to collaborate, as well as email, Slack, and Google Meet for daily communication.
What did you find most impressive about them?
Crombie’s communication and responsiveness are excellent, and they have really knowledgeable staff working for them.
Are there any areas they could improve?
No, we were very pleased with them.
Do you have any advice for potential customers?
Make sure to set expectations very clearly upfront, set deadlines, and ensure you follow up frequently.

The client submitted this review online.
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.

With offices in Chicago, Atlanta, New York and San Diego, the agency has been successfully helping healthcare clients achieve their business and brand goals since 1999.
For what projects/services did your company hire 4r Soluciones?
Drupal development
What were your goals for this project?
To implement updates to a patient-focused product website
How did you select this vendor?
Our internal development team needed to scale in order to handle a short-term expansion of web-development service needs. After considering several options, it was decided we would seek an external partnership. Several vendors were interviewed. 4r Soluciones was chosen to help with this project because of their demonstrated proficiency in Drupal and clear communications. Our confidence was further heightened by their efficient management of our questions.
Describe the project and the services they provided in detail.
The project had an accelerated timeline. They developed most of their updates during an intense one-week period. Text and image content updates were implemented between rounds of stakeholder reviews. Meetings and phone calls were held through-out the week to provide continuous contact.

Our team was comprised of a senior developer and producer. We dealt with a technical contact and an account contact from 4r Soluciones. They handled all communications within their team of Drupal developers.

Our internal project management team provided support and facilitation of all content development and reviews. 4r had a technical project manager managing the development lift on their side. Our lead developer and producer were in continual contact with 4r's PM.
