What people say

A few words from our clients.

When Yellow is working on a task, they understand how it will impact the product down the line. The team has provided great insight into our processes, making sure we don’t make small mistakes that will impact us in a larger way in the future.

Christopher Bianco

Christopher Bianco

CEO, Hyvery inc.

They were very accessible regardless of the time difference as well as communication was good. We had a couple bumps here and there regarding designs that were not originally discussed in our UX/UI designs but they were quick to find solutions as well as any needed changes we requested.

Bradley J.Humble

Bradley J. Humble

Co-Founder & CTO, DealStryker, Inc.

I liked working with them because they were good. With their work, we increased our mobile app’s user usage. We also got reviewed as one of the top 10 employee engagement services in Europe. Their project management was really good. They worked in sprints, and I always communicated directly with their developer. More importantly, they were attentive to our project's details.

Thomas Urban

Thomas Urban

Founder & CTO, Weffect

Browser compatibility and readability have increased markedly since the engagement began. Yellow's development process helped them beat deadlines and respond quickly to any technical concerns that arose. Their ability to bring creative ideas of their own to the table made them a valuable partner. Yellow typically understood exactly what the issue was and came back with a fix right away. 

Jerry Sparkman

Jerry Sparkman

IT Director, National Association of Tax Professionals

If you are looking for a partner to collaborate with for the development process, I would consider hiring Yellow. Yellow has an intelligent team of developers that collaborated on the project to build a quality app. They follow instructions seamlessly, respond effectively to feedback, and invest themselves in the overall success of the product. I would happily use them again if we needed developing services.

Chris Pointon

Chris Pointon

CTO, Racefully

Yellow is by far the best at helping us make decisions to push our company forward. I’d heard about them through a personal connection in the Bay Area. Yellow stands out because they’re invested in the results and clients. Every single person on Yellow’s team genuinely cares about what they’re doing. I really appreciate that about them and it’s the main reason we will continue our relationship for as long as possible.

William Hamilton

William Hamilton

Co-Founder, SmartPath.co

Yellow quickly and seamlessly assimilated into a fast-paced and nuanced workflow, completing all deliverables on time. Responsive to questions, updates, and issues, they have streamlined management operations and reduced work backlogs by directing communication to appropriate in-house team members.

Eric Morgan

Eric Morgan

Product Manager, Speed Digital

The new features have benn well received by users. Attentive and flexible, the team excelled at responding to stakeholders in a timely matter. Their technical expertise allows them to propose valuable solutions.

Ian Ross

Ian Ross

CEO, OppSites

Engaged, supportive, and invested in project success, the team offered constructive criticism, creative guidance, and honest communication. Their user-centered approach resulted in a unique and reliable product that operates well on all systems.

Jim Barkow

Jim Barkow

Founder, Famlicious Inc.

Because of marketing costs, the B2C application fell out of use in favor of a different B2B tool. Yellow was very focused on customer satisfaction, and they participate regularly in standups. They helped solidify features, and they thoroughly explained their process.

Sandro Tuzzo

Sandro Tuzzo

CEO, Separate.us

We're impressed with their loyalty and honesty. They were able to stay true to the original quote even though we needed to change and add a few requirements. They've done a lot of good work for us on all fronts, but it's amazing to see that they're able to stick to what they initially promised.

Jon Shower

Jon Shower

CEO, BlackBird

Mainly, I go by client feedback to judge Yellow’s performance, and the clients have been very impressed with their work. The team is exact in what they do, their delivery has been good, and they’re on time and budget.

Adam Plager

Adam Plager

CEO, QKSS

Their performance was good. I didn’t expect that kind of performance from someone working offsite. I was happy that they completed the project ahead of schedule, so we had some time left to work on additional projects and improvements.

Max Abukhovsky

CEO & Founder, Coverium
