Web Design Review from Jo Maney
DDC has been an excellent partner since we engaged with them in 2023. The DDC team worked with us to completely redesign our website and work to provide ongoing digital marketing services. The DDC team has been responsive, proactive, and thorough with their work. They are also very transparent about how they operate and how much time special projects will require. We have referred DDC to several clients and partners thanks to their outstanding process and product. DDC is a very professional, creative, and well-organized team.

Web Design Review from Sapna Doshi, Ph.D.
My experience working with Design in DC was incredible. Everyone was friendly, approachable, and seemed to genuinely care about helping create the best possible website for my business. They were also invested in making sure the process was one in which I enjoyed and felt taken care of. The regular meetings made me feel like I was a priority and that progress was continually being made. I so appreciated the attention to detail in regards to the user experience. The collaboration in understanding my wishes and desires for the website and user experience was met with patience and paying attention to detail on my behalf. Not only were they taking my suggestions but offering their own to help me maximize the potential of my website. The design and functionality is more than what I could have imagined. I know, undoubtedly, that the work that Design in DC did for me will help my business grow. After wasting money in years past on website designers, I was worried I'd be doing hte same here. I was wrong. I don't think I'll ever need to search for another website designer group again. I would recommend this group to anyone I know. Thank you, Design in DC! It was an absolute pleasure working with all of you!

App Marketing Review from Oleg Naumov
We were looking for a company that could promote our delivery app. We had a really hard KPI and special target audience so we needed a professional agency for effective ad campaigns.
By the right targeting, messaging and catchy creatives the conversion increased and CAC decreased by 20%. As a result, the volume increased by ~ 700%.
We had a rather hard goal to achieve, and we were surprised how easily the Mobio team handled the task.

App Marketing Review from Sergey Devyatov
We needed a company that could promote our mobile app. Our main goals were to acquire more relevant users for our app and find alternative sources for that instead of classic ones.
Mobio Team did a great campaign as a result of which we found our relevant audience and target with CPA close to KPI.

App Marketing Review from Sergey Alyautdinov
One of the main tasks of promotion was to motivate and encourage users who installed the application, but used it only once or never at all, to place an order.
An advertising campaign with a multi-format showed good results: it was possible not only to achieve KPIs, but also to exceed them. CPO decreased by 51%, CR increased by 15%.
Mobio really does what they promise. They have a lot of experience in our industry, so everything they did was 100% right and well-planned.
