What people say

weffect logo

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.

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.

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.

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.

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 participated regularly in standups. They helped solidify features, and they thoroughly explained their process.

We’re impressed with their loyalty and honesty. They were able to stay true to their 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.

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.
