Amazing and talented people. I’ve worked for both client and agency side and can can say their partnership is amazing. They truly care about ongoing operations and not just ending it at a project level. Highly recommend! Message me if you want specifics.

I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.

We had a great initial project with Ameex before they were purchased by Perficient. Post-support was slow, but acceptable, however as time went on, I stopped getting the level of communication and time itemization I was accustomed to. With Perficient taking over, things devolved pretty quickly, and despite multiple conversations with my account manager - nothing changed, even after bumping up hours to have more dedicated resources. Ultimately, I cancelled the contract this year. Disappointing because their team/work was stellar (and the development team is still solid) before, but the simple asks were continually ignored, and over time, I lost trust that I was getting the hours agreed upon.
Towards the end, there was also what felt like a lot of gaslighting of my concerns, and outside of an initial project, I cannot recommend Perficient for ongoing support.
Edit: I'm now bumping this to a 1 Star because I've spent the last 3 weeks digging into code and it's one questionable decision after another. Really poor.
