Webman Technologies's Review Sourced from Google
Sleepless Media did an outstanding job on our Shopify project. Their team combines creativity with deep technical expertise, making the whole process smooth and stress-free. They truly understood our brand, designed a store that looks stunning, and optimized it for performance and sales. Communication was always clear, deadlines were met, and they went above and beyond to deliver a result that exceeded our expectations. If you’re looking for a reliable partner for Shopify design and development, Sleepless Media is the perfect choice. Highly recommended!

Barry Pinto's Review Sourced from Google
Sleepless Media is the kind of web design agency that I've been wanting to work with for years. My company's website was in severe need of a redesign, and we knew that it was going to be a complicated project in terms of content migration, customizations, and attention to detail. I also needed a design agency that could work hand in hand with our SEO people. Fortunately I found Jon and team, who are not only extremely talented web designers but great listeners as well. Also a very patient team - we were far from a well prepared client in terms of having our site content ready to go, but they made the upgrade happen for us regardless. If you have been thinking about a redesign and need a Shopify partner that you can trust, this is your agency. Highest recommendation, and I plan on sending them all of our future web development business.

Victoria Comeau's Review Sourced from Google
I reached out to Sleepless Media after the company I originally chose to work with to transition from BigCommerce to Shopify did an awful job. What was supposed to be a three month project was now a year and a half nightmare. The team at Sleepless Media was so knowledgeable, transparent, communicative, and just amazing to work with. If I needed any clarification on anything, they didn’t hesitate to offer to hop on a call with me to make sure I knew what was going on. Every member of the team I have interacted with has been nothing but amazing. I can’t recommend Sleepless Media enough. The work they do is top notch, and worth every dollar. If you work with them, you know the project is going to be done and it’s going to be done exceptionally.

Web Design Review from Brian Yokely
It isn't often that you find a partner like Big Drop and I cannot recommend their fantastic team highly enough. Projects like ours are no small feats and their dedication to producing a successful outcome for us is unparalleled by other agencies. In addition to superior project management, their creative and strategic teams leveraged our brand to develop an aesthetic that is absolutely first-in-class, with functionality to match, and we couldn't have done it without them. I look forward to expanding our collaboration in the future. We needed a website refresh, and Big Drop helped us produce the best possible product. The team's professionalism and expertise were evident throughout the project, resulting in a website that exceeded our expectations. Working with Big Drop was a smooth and productive experience, and we were thrilled with the outcome of our collaboration.

Branding Review from Michele Zappula
Big Drop 100% gets who we are and what we need and we trust them completely. Their creative process is iterative and comprehensive, and have become a true extension of our team who has been fortunate to work with their top talent. We are consistently impressed by how well Big Drop brings forward concepts and ideas that have evolved our products and brand, and together, we have delivered some truly amazing items. I have been waiting to work with them, and it has easily been worth the wait. Working with Big Drop was instrumental in refining our brand identity and creating new digital properties. The agency polished our main brand and refreshed two sub-brands. It also developed four new digital assets. The team's creative vision and ability to interpret our goals were pivotal in achieving our desired outcomes. Big Drop's flexibility, knowledge, and commitment ensured it made adjustments to suit our specific needs.

Marisa Belaski-Farias's Review Sourced from Google
Mangrove has great people, who do great work. I initially collaborated with them at a tech company where they completely revamped our WordPress site. Recently, I engaged them to work with the headless CMS Sanity. In both cases, I primarily interacted with their account managers and developers.First, their project management is invaluable, especially for small teams like ours. Having a reliable point of contact to ensure we meet deadlines and stay on top of hours is crucial.Second, their developers are exceptional. They consistently exceed our expectations, offering valuable suggestions and going the extra mile to address any uncertainties.Overall, Mangrove's work has consistently impressed me and my teams, helping us achieve a wide range of marketing objectives.
World Affairs Communications Review from Google

World Affairs Communications's Review Sourced from Google
Prior to connecting with Mangrove, our organization’s website hadn’t properly been updated in years. After having revamped our organizational mission and branding, we needed a complete redesign to reflect our new direction and goals. It was a tall order given that we had years worth of events, broadcasts and other content to consolidate. Mangrove took the project head on and their team understood our needs from the beginning. Their approach was thoughtful and their team was organized, knowledgeable and responsive to our feedback and requests. The finished product is exactly what we had hoped for, and our website now perfectly reflects our revised brand. We couldn’t be happier with the Mangrove team and would recommend them to any mission-driven organization.

We are looking forward to enjoying the added credibility that comes from having a professional website and easier access to information by our clients. Everyone helping us with this project provided excellent guidance, and the mini video vignettes training us on the WordPress site’s background were perfect.
