SoftSolid has successfully completed eight important projects for me, delivering outstanding value and high quality. I have found this team to be knowledgeable, innovative, and dedicated to my success. I give SoftSolid my highest recomendation. To the SoftSolid Team: Kudos! Keep up the great work!

It was a real pleasure to work on two projects with SoftSolid. The team Robert and Michal are very friendly, communicative and very professional. Before placing an order with them for a custom project we had a long chat over the phone to get to understand their offerings and our requirements. Straight away it was noticeable the guys knew what they are talking about.

In relation to the projects itself, the guys delivered an outstanding job. They have listened to our brief and executed it immediately. No problems at all in relation to anything that needed to be changed.

Customer service after delivering the project was 5 stars too. The team was even willing to make small tweaks to the project after delivery.

I would highly recommend SoftSolid and will definitely be working with them again.

Softsolid has done multiple jobs for us now, satisfied with the work. They make a good diagnosis before they start working on an issue.

Great service! Good understanding of the customer's requirements, easy communication, fast delivery and very reasonable pricing. The add on Michal produced for us works great!
