From Molly Sharp, Senior Product Manager at PLOS:

"We've been really happy with Cloud City and feel lucky to have found them! We were impressed with their:

Incredible flexibility and willingness to lend a hand — When we found competing firms rigid, Cloud City was the antithesis, accomodating to pre-existing and changing requirements (such as the framework we were using, which changed midway through the project), and working on-site at our location.

Expertise and training — Having launched a project to build all-new content management tools with limited staff, we appreciated the collaboration between our developers and Cloud City's. We got the training and support we needed to get set up quickly and start delivering features right away.

Product Ownership — Everyone on the team truly 'owned' the project, making it easy for me to deliver a good product.

People — Cloud City was not only a good cultural fit but everyone on the team gave it their all. We've enjoyed the experience.

We couldn't have done what we needed without them and I would rate them as phenomenal. I would hire them all over again and have already recommended them to others."

"Cloud City worked more as partners and part of the team than as outsourcers or a typical consultancy. The relationship started with some free friendly tech advice over coffee and proceeded on to our hiring four engineers at the project's peak. They expertly trained up new staff as we ramped their team down. We were left far better off and more self-sufficient after the engagement than before! Thanks Cloud City!"

— Michelle Lam, CEO, True & Co.
