Mobile App Dev for Experiential Marketing Platform
“We’ve been nothing but ecstatic with CloudFlex. We intend to continue our relationship.”
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 lead product management for an events platform and a suite of related products that unlocks audience engagement for brand-minded customers.
What challenge were you trying to address with CloudFlex?
We needed help with mobile app development. In particular, we brought them in to cope with a key project.
What was the scope of their involvement?
When we initially contacted CloudFlex, we were looking to extend one of our mobile apps to include an in-app video chat. This change introduced a new interface and UX, along with related network calls required to perform those actions and open those channels. In the end, they introduced some key features, such as UX improvements, analytics tracking, and various testing services. We used Swift and Kotlin for these efforts.
After our positive experience with this critical project, we continued our relationship with CloudFlex as a form of staff augmentation. Since then, we’ve also worked together on a mobile app on Flutter.
What is the team composition?
We have an iOS developer, an Android developer, a QA lead, and a QA engineer on the team.
How did you come to work with CloudFlex?
We found them through a referral. They came highly recommended.

We’ve been working with them since May 2021.
What evidence can you share that demonstrates the impact of the engagement?
The first project was a great success. It supported one of our large brand clients, so our benchmark for success was just the customer’s satisfaction and our ongoing relationship with them. Overall, they’ve performed up to our expectations.
How did CloudFlex perform from a project management standpoint?
We’ve had some project management interaction from their side, but most of the project management roles are managed in-house. However, they’ve been great about being budget-conscious and raising concerns around slowdowns and obstacles to their performance. Moreover, they’ve performed above typical staff on a project, identifying areas of improvement and alternate approaches to achieve the project’s objectives.
Communication is mainly via Slack and Zoom. The frequency and their overall communication skills have been nothing short of impressive. Additionally, we use Shortcut for project management.
What did you find most impressive about them?
Their strength is their dedication to making projects and products a success. They have a product mindset above any competitor. They’ve identified weaknesses and the impact of decisions on existing and new products. Other teams often aim to get to the end state as quickly and easily as possible, even if it means introducing a certain amount of bad tech. Therefore, we really appreciate their team members; they come to these initiatives with the best solution in mind.
Are there any areas they could improve?
No, we’ve been nothing but ecstatic with CloudFlex. We intend to continue our relationship.
Do you have any advice for potential customers?
Come with an open mind regarding your expected approach and seek their input and advice. They’re more than trusted engineers that can build your idea exactly to your specifications. CloudFlex comes with a lot of experience; you’ll only benefit from them.

Advanced Video App Dev for Software Company
“CloudFlex has technical excellence and proficiency.”
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 CEO and founder of Yaza, a software company that helps battle fake news. We develop technologies that ensure videos are real and authenticated.
What challenge were you trying to address with CloudFlex?
We hired CloudFlex for their mobile app development services.
What was the scope of their involvement?
CloudFlex is helping us develop a real-time video app that uses advanced camera features. It specializes in manipulating and sharing large HD video files, so it’s not a trivial app to develop.
We plan to eventually use the app for TV; it’s a TV-quality video capture app for news organizations. Currently, it’s in the market for iOS users, but it will eventually be available on all platforms.
What is the team composition?
We work with three CloudFlex resources, including a project manager.
How did you come to work with CloudFlex?
CloudFlex was introduced to us by another dev shop that didn’t have the resources to resolve the challenges presented by the app.
How much have you invested with them?
We’ve incurred around $35,000.
What is the status of this engagement?
We started working with CloudFlex in June 2021, and the partnership is ongoing.
What evidence can you share that demonstrates the impact of the engagement?
We haven’t officially launched the app for news organizations, but we’re working on deals with other groups. Moreover, people who have used it give it a 4.5-star rating. It has also won awards. End users say the app is polished and robust. It doesn’t crash and it works.
Overall, I’m 110% satisfied with CloudFlex’s work — they’ve exceeded our expectations. They’re superb.
How did CloudFlex perform from a project management standpoint?
Their project management is excellent. I respect that they’re willing to argue with me — the most valuable developers are those that tell you when your ideas are bad and not those that simply do what you tell them. That’s critical to success. I have a master’s degree in computer science from Stanford, but CloudFlex always teaches me things — they’re highly sophisticated.
To communicate, we have a weekly hour-long Zoom call. We also do on-demand calls as necessary.
What did you find most impressive about them?
CloudFlex has technical excellence and proficiency. Their strategy is to go high, so they carefully choose their clients and hire only the best developers. The Ukrainian market is crowded, and they’ve chosen to go to the top of the market; they go for quality instead of quantity.
On top of that, we click together. We move quickly and finish each other’s sentences — it’s like they’re my own team.
Are there any areas they could improve?
No, there aren’t any. I couldn’t be happier with their services.
Do you have any advice for potential customers?
Bring CloudFlex difficult problems. If you’re not trying to solve hard problems, you can go to other teams that are less expensive. Remember that you get what you pay for — if you have tough challenges, then go for CloudFlex. They’re not no-code developers.
