      I worked with Akevo to build our Health Exams Portal, and overall it was a really positive experience. They understood what we were trying to build from both a technical and business perspective, which made collaboration easy. Communication was clear, timelines were realistic, and they handled changes in scope without friction. If youre looking for a development and marketing partner, I would highly recommend Akevo and will be working with them again in the future.

      We needed to automate a core part of our ops workflow and didn't want a generic off-the-shelf fix. Akveo took the time to understand our setup, proposed a phased approach that fit our budget, and delivered exactly what we discussed. On time and without surprises. Communication throughout was clear and consistent. Really impressed with their hands-on approach to AI development.

      We partnered Karma Jack to help elevate our brand, and they exceeded our expectations on every level. The creative team brought fresh, strategic ideas to the table and executed them flawlessly. From concept development to final delivery, their attention to detail and commitment to our goals was clear. They truly felt like an extension of our own team. If you’re looking for a group that combines creativity with professionalism and results-driven thinking, look no further.

      Dana Lang's Review Sourced from Google

      As the owner of GO Processing, a Detroit-based contract processing company, I can confidently say that partnering with KARMA Jack was one of the best decisions we’ve made for our brand. From the moment I landed on their website, I knew this was the team I wanted shaping our visual identity. They took the time to truly understand not just our business—but us as founders. That level of care shows in every detail: our logo, our website, our assets… and now, our new brand video. KARMA Jack helped us get our footing back when we were still Pulse Processing and stayed locked in with us through every step of our transformation into GO Processing. The revamped website? Absolute chef’s kiss—and Rebecka made sure every detail aligned with our new brand vision. A huge shoutout to Courtney, who led the creative charge and brought a whole new level of energy and clarity to our brand video. What she and the team created has given GO Processing the spark it needed to stand out in a very saturated (and often pretty dry) industry. This wasn’t just a branding project—it was an investment in our future. And it’s already paying off. If you’re looking for a team that listens, thinks big, and delivers visuals that actually reflect who you are—KARMA Jack is it.

      Shout out to Jono and Courtney for being so enjoyable and easy to work with. As a photographer they hired for a remote project, I would like to applaud their communication via Zoom, phone calls and text, which made it feel like we were working side by side. We were all true partners in making sure we got the right photo and video content for their client's needs. I would definitely work with them again in the future!

      Silver Spark Studio took my initial ideas brought them to life. They were attentive, the process was collaborative, and they were receptive to my feedback and made changes as needed. They helped me navigate a critical planning stage in my small business and I will continue to consult with them for future steps.

      Y. O.'s Review Sourced from Google

      Silver Spark delivered focused, constructive feedback that helped us see where the experience was falling short and where it was on the right track. They called out usability issues like the floating, unclickable cookie banner and lack of navigation back to the main site from portfolio demos—both small things that impact trust and flow. Their suggestion to replace client logos with actual work mockups shifted our perspective on how to better showcase our value. They also emphasized how underwhelming the hero section felt and encouraged us to treat it with the weight it deserves as a first impression. On the positive side, they acknowledged our strong branding and clear communication, and gave a nod to our solid SEO and best practices. Their tip to expand the FAQ as a low-effort SEO boost was especially helpful. Overall, the feedback was thoughtful, to the point, and gave us a practical path forward.
