      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.

      K Fortune's Review Sourced from Google

      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.
      Y. O. Review from Google

      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.

Their guidance helped us move the project forward with confidence. Throughout the process, they were professional, responsive, and clearly dedicated to delivering quality.
