BACKGROUND

Introduce your business and what you do there.

I’m the CEO of a sports analytics company.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with DS Stream?

We were looking for a consulting partner to provide us with guidance and implementation of workflow scheduling service for multiple data processing pipelines. Since we don’t have experience with these technologies, we needed a partner to help us choose the right solution for our needs.

SOLUTION

What was the scope of their involvement?

It wasn’t a very big project, probably more of a consulting gig or a quick prototype. Initially, we reviewed several possible workflow scheduling tools. DS Stream recommended a powerful open-source tool that was developed by a high-traffic online marketplace.

After looking at our requirements for pipeline processing, they designed the most critical parts of the scheduling. They also implemented some of the pipelines.

What is the team composition?

We worked with 2–3 people from their team, including a project manager.

How much have you invested with them?

We spent less than $10,000 on their services.

What is the status of this engagement?

We worked together from July–August 2019. We’re considering hiring them for our next project.

RESULTS & FEEDBACK

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

This project has increased our efficiency and reduced the number of data processing failures. Previously, we were running paper pipelines semi-automatically. Now, we’ve managed to automate 90%–95% of the work, so we don’t need to spend as much time running it.

How did DS Stream perform from a project management standpoint?

It was fine. They delivered what we expected. We didn’t have any issues.

What did you find most impressive about them?

They have excellent technical specialists compared to other companies. The people we work with are quite similar in terms of seniority. It wasn’t like with other companies where you get one or two juniors and a senior. We got a highly experienced team from day one.

Are there any areas they could improve?

No, everything was okay.

Do you have any advice for potential customers?

It’s worth clarifying the requirements and the expected results from the beginning. Let them work on the best solution. Don’t provide your ideas for a solution because you may get something better because they’re quite experienced.
