      I would give 0 stars if I could. This company dragged out our website creation process from 6 months to over a year. They continuously ignored requests, ignored our direct emails, ignored files we provided, and on. The final product was delivered full of 404 errors, spelling and grammar mistakes, incorrect files, missing files, triplicate files, and on. We were passed around from person to person throughout the entire process. They told us they understood the needs of an HRA, but continuously betrayed that statement. They ignored our request for team training on the new site, which was part of our agreement. Stay away from this company.

      Planeteria is a great organization to work with. Tyler and his team are super responsive and the the product they produced for us is above and beyond what we anticipated at a reasonable price point. I will definitely work with them again in the near future, and would happily refer anyone to Planeteria and their team of tech pros.
