Feedback summary: 

While stakeholders ceased working on the project, they were pleased with the high-quality code. Demo users praised the solution’s appearance and functionality. A flexible team, Ulam Labs seamlessly adapted to agile working methods. They are a deadline-oriented group.

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 head of development at NMR. We are a media consultancy that helps companies manage and distribute their video content.  

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Ulam Labs?

We hired Ulam Labs to build a web application that would manage the administration, the storage, and the UI of a solution. We’d won a European research grant to create a commercially viable, sustainable product, and we were going to bring it to market for customers in the media entertainment space. We would work with three companies to build the solution.

The final product would monetize and add value to video content. It would enrich metadata by using AI to analyze video content (e.g. it could perform quality analysis or facial recognition). The solution would also be used to analyze video streams on a real-time basis such as courtroom footage. 

SOLUTION

What was the scope of their involvement?

We needed them for their frontend development skills, as the solution required frame accurate video players and an optimized web browser. We gave them in-house designs for the web application, which they implemented in React with TypeScript.

They used Python to build a Django application that would expose API functionality. Technologies used also included Javascript. 

What is the team composition?

We were working with 3–4 people. In addition to development, the team performed project management and operations functions.

How did you come to work with Ulam Labs?

I had an engagement with Ulam Labs at my previous company, and I got good results from the team. I trusted them and was already aware of how they worked. I also knew they had quality engineers that could deliver the results I needed. In addition, they’re less expensive than similar companies in the United Kingdom market.

How much have you invested with them?

We invested about $60,000.

What is the status of this engagement?

We worked with them from January 2018 until May 2018.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

They delivered a high-quality product in a timely fashion. I didn’t have any problems with the team—they were a pleasure to work with. When we went to trade shows and demoed the product, the feedback was always really good. Everyone loved what they saw, and the solution worked well. It’s still being demoed today.

It’s difficult to provide other metrics because our parent company decided to pull out of the European engagement, and the project was put on ice. However, other companies are still running with it. 

How did Ulam Labs perform from a project management standpoint?

They had a very flexible workflow, which worked well for us. Team members were familiar with the agile practices we were running. They ran sprints and were available for standups. When a deadline came around, they were willing to work on a weekend to deliver the results on time.

What did you find most impressive about them?

They delivered high-quality code. The team has the expertise to implement frontend development in the most efficient and modern way possible.

It was easy to communicate with Ulam Labs. There was zero language barrier as they spoke impeccable English. 

Are there any areas they could improve?

I’d like to use them more often, so I’d like their company to grow. Hopefully, their successes will allow them to grow larger, and we’ll be able to engage in bigger projects.

Do you have any advice for potential customers?

Future clients should try to meet the team in person and develop a face-to-face relationship.  Consistent communication is key because it makes the communication barrier as small as possible. Clients should also make sure their requirements are clear.

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 COO of a small mobile virtual network operator.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Ulam Labs?

We were looking for developers.

SOLUTION

What was the scope of their involvement?

We’ve been working with Ulam Labs for 2–3 years, and they’ve become almost a part of our company. They’re an external team, but they work with us continuously.

When we started the collaboration, Konrad (Co-owner, Ulam Labs) reviewed all our processes and gave me advice on what we should change. They were involved in building payment processes and fixing bugs. They provided backend web development using different technologies, usually for new features, but also for bug fixing. We have in-house Python developers, and our website is built on Django, so this is our main focus. They’ve also proposed a lot of new technologies. Some of the features they’ve developed include an automatic payment system for our customers, a new loyalty business module, and a prepaid SIM card registration process done in-app.

What is the team composition?

We worked with three senior developers from their team in the beginning. We’re currently using two, but we will add another member again soon.

How did you come to work with Ulam Labs?

I found Konrad on LinkedIn and found out that he was working in the same building as us, on the same floor. This was a huge advantage in the beginning, given that they could visit us every day from the first hour for stand-ups. I was impressed with their experience in development. Compared to other companies, I wouldn’t need to put in as much time and effort to involve them in our processes, which was a big added value.

How much have you invested with them?

The total cost of their work has been around $200,000. We plan to work with them more.

What is the status of this engagement?

We started working with Ulam Labs in September 2016 and we have an ongoing relationship.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

I received feedback from my team of 20–25 people, including developers, project managers, and product owners. Ulam is a professional team, and time is not an issue for them; if they have to stay longer, work harder, and work faster, they will do it. They’re always prepared and focused.

How did Ulam Labs perform from a project management standpoint?

We worked on a single project in the beginning while we were getting to know each other, but we later started to work in Scrum, and they became involved at each level of the development. There was no set area where we used Ulam; we could use them everywhere.

They are seniors so they have a lot of experience, and they work in a professional way. We provide the right kind of atmosphere for them, but, had the process on our side not been prepared well, they would have mentioned it. From my point of view, Ulam requires a professional atmosphere and work process.

We’re not working within the same building anymore, but they’re still on time when they visit. They visit us a few times per week. Aside from this, we use email and instant messaging like Slack. They’re always available, including weekends and holidays.

What did you find most impressive about them?

They have senior developers, and, although they’re an external company, they’re dedicated to the work. Much of their work is related to customer service and happiness. We’re a customer-oriented company, and they know and understand this. They fix a lot of small issues and bugs, and this hasn’t been a problem for Ulam. They think about the satisfaction of the end user; they take this into account, and they’re also quite product-oriented, which is nice.

Are there any areas they could improve?

Ulam is a great team, and I regret that they’re not part of my own team. They’re stable and they want to have long collaborations with their customers, but professional engagement is different with an external company than it is with an internal team.

Feedback summary: 

Ulam exceeded expectations—not only coming in under budget and beating deadlines, but also in delivering workable solutions when they were sometimes thought to be impossible to develop. This combination could lead to future engagement.

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 former CEO of Sandpiper Consulting and GotMyJobs, Inc.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Ulam Labs?

I first engaged with them when I was CEO of GotMyJobs. We made a software-as-a-service (SaaS) solution for small to mid-size construction management companies and needed help with backend Python development.

SOLUTION

What was the scope of their involvement?

We worked together across two separate engagements. One for GotMyJobs and another when I started Sandpiper Consulting. For GotMyJobs, they helped with backend architecture, coding, and minimal design work based on the wireframes I provided.

When I was with Sandpiper, we contracted Ulam to help with a client’s front- and backend development. That project was a rewrite of a Visual Basic app. I provided wireframes and they worked from there. They transformed the existing code into a Python backend and wrote the UI in JavaScript. We used Angular for the frontend work and Django for the server.

What is the team composition?

I worked directly with three developers on both projects.

How did you come to work with Ulam Labs?

We originally found them on Odesk, which later morphed into Upwork.

How much have you invested with them?

I spent over $100,000 in total.

What is the status of this engagement?

We started working together in 2015. Our last project concluded in mid-2017.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

I hired them for two separate projects, so clearly I thought they were good. They’re one of the best developers I’ve worked with: super-hardworking, smart, and able to get things done quickly. The end user on the Sandpiper job was very happy with the results. They didn’t think it was possible to rewrite their software, but we did it under budget and on time.

How did Ulam Labs perform from a project management standpoint?

I did a lot of the project management throughout both engagements. However, they’re organized and good at managing development sprints. We communicated through Slack, Google Hangouts, and used Jira for test management.

What did you find most impressive about them?

They’re top-notch developers and I’d definitely work with them again.

Are there any areas they could improve?

I don’t have any serious complaints.

Do you have any advice for potential customers?

Hire them; they’re great.

Feedback summary: 

Positive internal feedback, higher customer retention rates, and site stability highlight Ulam’s work. They’re very responsive, but also honest in addressing delays or concerns. Their desire to understand overarching business and project goals also sets them apart from the competition.

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 CEO and Founder of Scent Truck, a direct-to-consumer fragrance brand that allows individuals to create customized fragrances. We also create formulations for enterprise, using data about the scents consumers gravitate toward to help businesses create products.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Ulam Labs?

We had some developers working on a website stack migration to Django, but we needed more manpower. Over time, our needs have evolved into building new applications as well.

Our product line is more complicated than traditional product lines. Through the use of a recommendation engine on our website, we're able to determine and generate the ideal scent for a customer based on a number of factors. This process produces unique products that, therefore, lack SKUs [Stock Keeping Units]. For that reason, Shopify isn't an ideal platform for us.

Additionally, collecting feedback from customers to improve our recommendations is a key part of our business.

SOLUTION

What was the scope of their involvement?

Initially, Ulam built our entire order management system, automating user feedback and providing customers with a “scent specialist” or customer service representative. The system allowed for customer support staff to manually alter orders if needed.

Their team also handled various frontend projects, while gathering data on how customers were using our website. Using our original design, they built out custom features and made significant changes to the website overall.

At a certain point, Ulam started handling the majority of our development work and continues to update and monitor the site.

What is the team composition?

I mostly work with a project manager and a few others on their team.

How did you come to work with Ulam Labs?

I found them through Upwork.

How much have you invested with them?

We've invested $50,000–$60,000.

What is the status of this engagement?

We started working together in August 2017. Although they completed the Django migration in December 2017, Ulam continues to maintain our website.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

We've received a lot of positive feedback from members of our team. Website performance and customer retention has increased, and I'd definitely say that our business has improved as a result of their work.

How did Ulam Labs perform from a project management standpoint?

Using Slack has made their team especially accessible. They're very responsive and dedicated. I remember having trouble with the site on a Friday night, for example, and they stayed up working on it for us. They're great about making sure their clients are happy. 

What did you find most impressive about them?

I'm most impressed by their project management and communication approach, especially compared to other contractors I've worked with. They're organized and take deadlines seriously, but they're also transparent about any issues that may come up and delay work. As a business owner, that transparency allows me to plan around timelines with advanced notice; that's a rare quality to find in a web developer.

Are there any areas they could improve?

No. I think they're great.

Do you have any advice for potential customers?

Entrepreneurs tend to be impatient and dive into projects quickly. Ulam has a great onboarding process, so I recommend taking your time in the beginning to ensure their developers are fully up to speed on your application and company. The process shouldn't be rushed.

Feedback summary: 

Ulam is extremely diligent in resolving issues. Despite a more relaxed organizational structure, they continue to improve by developing an effective and polished project management system. They also go above and beyond expectations to provide impactful and helpful advice to further high-quality results.

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 CEO of RankSense, which is an SEO software company.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Ulam Labs?

Our previous DevOps vendor began placing junior staff on our account and billed us for their mistakes. They also made a billing configuration error that tripled what we were paying for on our Google Cloud account. The situation became very desperate and frustrating, so we reached out to Ulam to get us back on track.

SOLUTION

What was the scope of their involvement?

Our immediate and urgent need was to bring down the cost of our Google Cloud services. They audited our account to assess what was driving up costs and figure out a way to lower costs. They then corrected the billing mistake by making changes to our infrastructure within about a month.

From there, Ulam served as our DevOps vendor and continues to do so.

What is the team composition? 

I work with Konrad Rotkiewicz [Lead Full Stack Python Developer and System Engineer, Ulam Labs] who serves as the project manager to our account. I also work with two developers.

How did you come to work with Ulam Labs?

I found them on UpWork and recruited them to do a small project to gauge whether they would be a good partner. They didn’t disappoint, so I decided to bring them on full-time.

How much have you invested with them?

We invested between $50,000 to $60,000 in our partnership with them.

What is the status of this engagement?

We began working with them in September 2017 and continue to partner with them for DevOps needs.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

They’re very responsive to our clients. Because of their diligence, I’m actually able to connect clients directly to them to resolve issues. For example, we recently had a client that was failing their PCI compliance scans. In order to fix the problem, we needed to disable outdated SSL ciphers, but Google Cloud didn’t have the capability to disable them. Konrad work diligently with Google Cloud support to allow us access to an alpha version of the Google Cloud infrastructure that would enable us to disable to the SSL ciphers. They work diligently for weeks and ultimately resolved the issue for the client.

How did Ulam Labs perform from a project management standpoint?

They’ve done very well. I was previously managing their developers myself, but Konrad is hiring more people and directly managing them so I don’t have to. The project management system they’re developing among themselves is effective — we’re able to see their progress. They know how to prioritize, so we don’t have to wait a long time for things to be completed. 

To communicate with them, we use Jira, eHub, and Slack.

What did you find most impressive about them?

It’s very difficult to find vendors who are willing or able to give you impactful suggestions to better your project. Most developers I’ve worked with don’t challenge your plans; they just do what they’re told. Ulam provides their expertise and makes helpful suggestions backed up with data to better a project’s outcome. I truly appreciate their input — it’s one of the reasons I continue to have them on my team.

Are there any areas they could improve?

More structure and planning in place would be appreciated. For instance, keeping clients updated on when Ulam will have someone from their team available for assistance would be great. Right now, the process is a bit informal.

Another thing they could improve would be to offer a 24/7 support service. We are able to contact them in case of an emergency, but more availability would be convenient.
