      Web Development Review from Juan Guillermo Serna Agudelo

      Somos Gente Digital exceeded our expectations and allowed us to achieve the transformation that our company needed so much since the web renovation.With a highly qualified interdisciplinary team, committed from start to finish and with a responsible application of agile methodologies, we achieved a synergic work with very significant results that make our digital assets more aesthetic, agile, secure spaces, with improved and new functionalities; all this always thought from the user experience.It is worth recognizing that the deliveries exceeded the initially agreed deadlines, but I understand and recognize that it was due to the new ideas and challenges we faced together in the process to achieve what we have today.To your entire team, my total admiration and gratitude. I have full confidence in your work and will recommend you whenever I have the opportunity to do so.

      We requested a quote for maintenance and they never sent us the proposal. It didn't seem very diligent, but... We still had to look for another alternative for what we needed.

Learn more about DesignRush Agency Ranking Methodology.

Sources

DesignRush sustains a directory of over 30,000 agencies categorized by service category, location, expertise, and reviews. We build our database in two ways:

  • Our dedicated team of agency experts actively searches the web for top-performing companies. We then pull information from their websites, online presence, and client testimonials to verify their status and qualifications prior to listing.
  • The agencies listed get notified of their profiles on the website and they can choose to claim it or not, which suggests their availability for more collaborations.

Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.
