It’s podcast listening app, so the main functionality is streaming and listening to audio files, as well as watching videos.

client over the phone. Below is an edited
transcript.
BACKGROUND
Introduce your business and what you do there.
I’m the founder of ASO Giraffe, a mobile marketing tool for running A/B testing for iOS and Android developers.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Flexum?
We were looking to formalize our development process as we only recently came out of an MVP phase with an external developer. We wanted to devote full-time resources to developing the application.
Like any growing startup, we were looking to build new functionalities and make our platform more stable. We needed help in software development.
SOLUTION
What was the scope of their involvement?
Flexum has taken over the development of our app from our external developer. They do software development, and they build, manage, and service our platform. Our app is based on JavaScript, and we use React for the front- and backend.
Our initial interaction revolved around having a transfer of knowledge from our external developer to Flexum. In that process, Flexum understood our problem and the app’s code. They figured out ways how we could seamlessly transition, and they also thought of the necessary functionalities for the project.
The development is ongoing, and we work as an agile scrum team with objectives, roadmaps, and sprint demos. We have expectations in terms of reporting, mainly around what’s being delivered in sprints.
We also evaluate new designs and development, and we break up designs into smaller bodies of work. Flexum provides ongoing maintenance to the application.
What is the team composition?
I work with Myron (CEO & Co-Founder), Alina (IT Project Manager), and a software engineer.
How did you come to work with Flexum?
I previously worked with Myron, and I knew him to be a thorough, considerate, and thoughtful engineer. Luckily, when I needed a software development agency, he was also available.
I decided to progress with Flexum because Myron was a good worker, had an excellent technical understanding, and could tackle challenges.
How much have you invested with them?
We’ve spent between $25,000–$30,000.
What is the status of this engagement?
We started working together in February 2021, and it’s ongoing.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
We don’t have any specific KPIs for this project. Ultimately, our objective is to deliver on time, as specified, and efficiently. I’m working actively on the project as well, and I see the output they’re making. Flexum meets my expectations on all fronts.
How did Flexum perform from a project management standpoint?
Flexum is professional, and they have a nice set-up and good approaches to sprint planning, delivery, and feedback. They also proactively address challenges that come up. We use ZenHub and GitHub to collaborate.
What did you find most impressive about them?
Flexum has done a good job of tackling the complexity of the work we’re doing. When things don’t go as planned, they’re very open and honest about what’s happening. They seek to understand and solve problems together.
Generally speaking, they do a good job of breaking down sophisticated tasks. When delivering those tasks, they can adapt to issues through good communication. Lastly, there’s little that needs to be done with their output — they’re thoughtful of major components in their work.
Do you have any advice for potential customers?
I recommend working with Flexum. They are experienced in software development.
