Client Testimonials
Rob Burns, President, Bunk 1![Bunk1 Application]()
The experience I've had with other firms is in direct contrast to what FullStack did. I'm comparing them with two other firms I worked with in the past. They care a lot about what their clients are doing. They bring their ideas and concepts to the table. I felt like they were on my team. They added a lot of value in terms of ideas and continue to do so. No matter who's working on the project you feel like they care about the work that's being produced.
Executive Director, Valley CAN![ValleyCAN Application]()
FullStack Labs' managers have been engaged throughout. The whole project management staffing, matching team to task has been fantastic. All their staff is very committed. I'm very aware of how much bureaucracy there is in the tech world, and we've gotten nothing but solutions. I am totally happy with their approach to everything, their integrity, honesty, the whole thing. It's great.
Anna Sadovnikova, CEO, MomKit![MomKit Application]()
We were very happy with the way the whole process was facilitated. We started talking to FullStack Labs three months before we signed any contract with them. We met with them in person several times. We wanted to find out what their philosophy is. Both Brian and David are fathers with young children, so they understand the importance of the work we are doing. That shows through in their work. It was obvious they cared deeply.
