Stellum is developing a web-based platform for a nonprofit organization from scratch. They’ve collaborated with the client to design the UX/UI and organize the platform.
The platform is on track to be completed by May 2022. So far, Stellum has completed as much development as their previous vendor in just a fourth of the time and at a higher quality. Stellum provides project updates during their weekly meetings with the client. The partners collaborate well.
A Clutch analyst personally interviewed this
client over the phone. Below is an edited
transcript.
BACKGROUND
Introduce your business and what you do there.
I’m the director and founder of a nonprofit organization.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Stellum?
We needed a web platform that could run our organization’s activities.
SOLUTION

Stellum is developing a web platform from scratch based on my guidance. Their team has helped me put together the UI/UX design and organize the platform.
What is the team composition?
I work with a project manager, who oversees four developers and a UI/UX teammate.
How did you come to work with Stellum?
I found Stellum on Upwork — they replied to my job posting. I interviewed four vendors that answered the posting, but after those interviews, I decided to hire Stellum. Stellum’s team spent time learning my business goals and then found ways to improve my initial plans, which I liked.
How much have you invested with them?
I’ve invested around $12,000 with Stellum.
What is the status of this engagement?
My partnership with Stellum began in November 2021, and it’s ongoing.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
We’re a month out from the project’s completion. I’ve worked with other developers in the past and wasn’t satisfied with their work. However, with Stellum, I finally see results. They’ve done just as much development, at a higher quality, in three months as our previous developers did in a year.
How did Stellum perform from a project management standpoint?
Stellum provides project updates in our weekly meetings— they have impressive project management. We use Trello to manage the project and Slack to communicate.
What did you find most impressive about them?
Stellum has invested time in understanding my project goals. They’re not just checking boxes and moving on — Stellum is collaborating with me to improve the overall project and their deliverables.
Are there any areas they could improve?
I can’t think of anything Stellum can improve.
Do you have any advice for potential customers?
I’d advise customers to go into a partnership with Stellum with an open mind. It’s important to listen to what Stellum’s team says because they’re dedicated to improving customers’ projects.

OPPORTUNITY / CHALLENGE
For what projects/services did your company hire Stellum, and what were your goals?
We wanted to build an online tool, integrated with our TINT platform, which helps our users to build their own yoga sequences. Stellum helped us to build a rather sophisticated MVP of the product in just about 4 weeks time.
SOLUTION
How did you select this vendor and what were the deciding factors?
We have worked with Stellum before and were satisfied with their services. After doing a couple of other interviews, we decided for Stellum because their offer was fair. They were available and proactive in regards to how to make the product better.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
The scope was building two pages for a canvas area and a form of pose library. The application was planned to work for web, mobile and tablet viewing. So the project was to build a complex web application delivered from scratch with Stellum handling PM and QA alongside with the development itself.
Steps on the way:
work with business requirements and provide estimation
run quick weekly iterations with tangible increment and regular communication
deliver app fully within dedicated budget and time
Key Deliverables:
interactive web application with Drag & Drop feature, add, move and delete poses, export PDF function, embedding tutorial video and a comprehensive pose library with search bar and tag search logic.
Technologies:
Frontend: React, Tailwind
Backend: Next.js
DataBase: Mongo
Cloud: AWS, Mongo Atlas
How many people from the vendor's team worked with you, and what were their positions?
We had a task force of three people consisting of project management, one developer and one QA engineer.
RESULTS & FEEDBACK
Can you share any measurable outcomes of the project or general feedback about the deliverables?
The deliverables were on point and everybody in the team was very happy about the outcome and impressed by the short amount of time in which the project was developed.
Describe their project management style, including communication tools and timeliness.
We are very happy with the overall project management, communication, keeping on top of tasks and sticking to timelines. We mainly used Slack for direct communication and jour fixe calls.
What did you find most impressive or unique about this company?
They always came up with suggestions and different options how to approach and solve a problem. Also, they had a great ability to explain the technical process in a way that is understandable also for people who have not so much expertise in this area.
Are there any areas for improvement or something they could have done differently?
There were some minor bugs along the way, mainly on the design side, but they were very quick to fix all of them.

BACKGROUND
Please describe your company and your position there.
I'm the owner of Membia which is a service to enable clubs in Germany, Austria and Switzerland to manage their club and club members.
OPPORTUNITY / CHALLENGE
For what projects/services did your company hire Stellum, and what were your goals?
We hired Stellum to develop the MVP of Membia and create the web application based on our design. The goal was to have the MVP for testing purposes as fast as possible and reflect all necessary features.
SOLUTION
How did you select this vendor and what were the deciding factors?
We searched for freelancers on upwork.com and I shortlisted 3-4. After several calls with different agencies and freelancers, I decided to go with Stellum. The main deciding factors was the good portfolio of Stellum and also a very good and easy communication which was important to me.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
We had a kick-off meeting and from then on we used to talk twice a week to discuss the next steps and possible problems. Before we started developing Stellum consulted on the way to structure the application and also brought their way of thinking to the table. This really helped because it's essential to have a partner who also thinks and tries to find the perfect solution. The key deliverable was the MVP and from there we will iterate in smaller steps to provide more features.
How many people from the vendor's team worked with you, and what were their positions?
From Stellum there were 3 people involved: A project manager, a QA engineer and a developer.
RESULTS & FEEDBACK
Can you share any measurable outcomes of the project or general feedback about the deliverables?
For now there are no measurable outcomes because we've just released the MVP and onboarded the first testers.
Describe their project management style, including communication tools and timeliness.
We had update meetings twice a week and communicated mainly in a slack channel. For task management we used trello and for documentation we used notion.
What did you find most impressive or unique about this company?
Their most impressive parts were the communication and trust we built in such a short time I always feel that Stellum does everything to make me happy and always acts reasonable when problems appear.
Are there any areas for improvement or something they could have done differently?
I think Stellum can improve at delivering a given design exactly as it should be and should pay more attention to details. But they are already working on it.

BACKGROUND
Please describe your company and your position there.
The Quantum Daily is the leading resource dedicated exclusively to making Quantum Technology accessible through news, information, media and data.
OPPORTUNITY / CHALLENGE
For what projects/services did your company hire Stellum, and what were your goals?
We appointed Stellum to develop a new, feature-rich, web UI to deliver data-driven business insights to our users.
SOLUTION
How did you select this vendor and what were the deciding factors?
We selected Stellum based on skillset, experience and project price estimates. Stellum were responsive, helpful and professional throughout the selection process.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
Initially, Stellum was tasked with developing the new front-end UI from scratch, making use of existing APIs. The UI development was delivered on time, on budget and to spec. We then expanded the scope of the project, to include changes to the back-end required to deliver new functionality.
Stellum were able to accommodate the requests for this second phase of development, which was managed as a lean/Kanban project working through a prioritised backlog of features. The tech stack included React, Python and Django. The key deliverable of the project was a successful go-live of the new site.
How many people from the vendor's team worked with you, and what were their positions?
Three people from Stellum worked on the project (front-end developer, back-end developer and project manager). We worked directly with the project manager, who coordinated all development activity, managed the Kanban board, communicated estimates for approval, and provided regular updates.
RESULTS & FEEDBACK
Can you share any measurable outcomes of the project or general feedback about the deliverables?
Although we expanded the scope of the project partway through, Stellum were able to flex up to meet our requirements, and successfully delivered the new site, including new features. The new site launched successfully in October 2021. Based on their professionalism, reliability and talent, we hope to work with Stellum again in future.
Describe their project management style, including communication tools and timeliness.
Communication was excellent throughout, and Stellum provided frequent and clear updates. We used Slack, Trello and Figma extensively to collaborate, respond to blockers, prioritise activities and clarify design principles. Stellum did well to accommodate our stakeholders across multiple time-zones.
What did you find most impressive or unique about this company?
The quality of the software developed by Stellum was excellent, and the pace of delivery was very impressive. I’ve really enjoyed working with Stellum, and I found them to be reliable and professional in their approach. They went out of their way to help us through unforeseen challenges, and they now feel like part of the team.
Are there any areas for improvement or something they could have done differently?
I can’t think of anything.

Picking up from a previous vendor, Stellum developed a health app for a medical data analytics company. The team was tasked with cleaning up the app's code, implementing more features, fixing bugs, and more.

BACKGROUND
Please describe your company and your position there.
I am the founder of the company and responsible for the initial MVP mobile application.
OPPORTUNITY / CHALLENGE
For what projects/services did your company hire Stellum, and what were your goals?
The goals were to clean up the mobile app code (React Native) and get it to the point where it can run on my personal device for testing and regular use.
SOLUTION
How did you select this vendor and what were the deciding factors?
We search via Upwork and found several vendors. Stellum stood out with their previous experience developing similar applications and quick response time.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
React Native app was designed and partially implemented. Looking for someone to fix it, clean up the code, and finish the remaining features. App is for personal management of a specific health condition. Includes these primary components: test result and history chart, daily dose and dose scheduler, pill inventory, community activity feed. App should function offline and sync when possible.
Currently implemented with Firebase and Google Cloud Functions. Serverless approach is critical. Hi-fi designs are complete and available as well as existing codebase. Expect weekly updates from the developer.
How many resources from the vendor's team worked with you, and what were their positions?
A primary developer and QA tester were assigned to the project.
RESULTS & FEEDBACK
Can you share any measurable outcomes of the project or general feedback about the deliverables?
The original code (done by a previous vendor) was very bad quality. Stellum was able to take this and vastly improve it by converting it to TypeScript. They were then able to find bugs via QA and fix the worst ones quickly and help me get the app into TestFlight.
Describe their project management style, including communication tools and timeliness.
Roman was very easy to work with and we had regular meetings to review the project progress. They were able to organize the sprints and help define the deliverables.
What did you find most impressive or unique about this company?
They were able to work with terrible code, fixing it and creating a working prototype very quickly. Clearly, they are experts in mobile React Native apps.
Are there any areas for improvement or something they could have done differently?
No complaints.

They have great communication and the willingness to work hard when needed (ex. before the first paying clients checked in the platform). Fair and transparent pricing.

transcript.
BACKGROUND
Introduce your business and what you do there.
I own a healthcare technology company.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Stellum?
We needed help developing our patient-facing mobile application, and one of our provider portals
SOLUTION
What was the scope of their involvement?
They built our app for iOS and Android, using React. We had an existing platform that we were adding to on the provider side, so we were able to give them very specific instructions for what needed to be housed in the patient-facing app. The team worked on the user interface, as well as the backend database component, as well as the testing and deployment. We’re going to continue working with them to further build out the app and add to its functionality.
What is the team composition?
We worked with five people from their team.
How did you come to work with Stellum?
They were a referral from someone else that I’d worked with. I trusted the referral and Roman (CEO) is awesome to work with, and he’s committed to the project.
What is the status of this engagement?
We started working together in March 2020, and our work is ongoing.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
The application is currently live, and the feedback has been great from everyone who’s interacted with it. The patient-facing piece of it is intentionally easy to use, easy to understand, and simple. It’s not complex or intimidating at all.
How did Stellum perform from a project management standpoint?
They’re awesome. We communicate via Slack and three other collaborative project management tools. We also talk on the phone twice a week to go over project updates.
What did you find most impressive about them?
The talent, in terms of their ability to execute and deliver on everything they said, is definitely a strong point. It also feels like Roman and his team are invested in my project. They truly want to put out a high-quality product, which I appreciate as a business owner.
Are there any areas they could improve?
Honestly, I have no complaints whatsoever.
Do you have any advice for potential customers?
My advice is to have a clear understanding of the project’s scope. It’s more so to be efficient when it comes time for development.
