      Web Development Review from Woody Klemmer

      They were friendly, smart, engaging, overly competent, and competitively priced. After a few meetings with the founding team, I was confident they would deliver on what they promised and they did. We were also able to sit down face-to-face, which was comforting and valuable.

      Web Development Review from Nick Herbold

      We met with several firms when looking for help with this project. Gnar stood out for a couple reasons; during our initial talks they had a grasp of the projects challenges and some good insights based on past experience for how to approach them, were willing to work in a style that matched our style and were willing to work alongside our team, making sure our engineers fully understood the code they would inherit.

      Web Development Review from Joe Lind

      The Gnar totally integrated with our in-house team. They provided both horsepower and additional expertise to help us to architect and deliver everything from minor bug fixes to major new features. They quickly earned the respect of our team and became a trusted resource. Gnar was easy to deal with from a business perspective, and the talent they delivered was top-notch. We would highly recommend The Gnar Company to anyone looking to accelerate development.

      Ben Lee's Review Sourced from Google

      My engagement with SLIDEFACTORY has been one of the best working experiences of my career. After launching multiple SaaS products as a product manager, I've worked with a fair number of technical teams ranging across a variety of tech stacks. SLIDEFACTORY has proven to be one of the most competent, agile, and customer obsessed teams I've worked with. After launching my own business and needing a detail oriented tech arm to execute, Mark and Tom were the people I needed to bring my vision to life. I owe them a lot and I look forward to the things we'll accomplish together.

      I had a fantastic experience working with Mark at The Slide Factory. He was incredibly helpful throughout the entire process, asking thoughtful questions to ensure every detail was just right. His attention to detail and commitment to getting it perfect really stood out. The final product turned out beautifully, and I couldn’t be happier with the results. On top of that, Mark was kind, professional, and a pleasure to work with. Highly recommend his services!

      Peter Kirwan's Review Sourced from Google

      The Slide Factory is one of those companies you don't often have the privilege of working with. It's not just that they do high-quality work, listen to the client, meet your deadlines, and bring insights that may not have been on your radar. Those are important, of course. I think I value most that they are nice people to work with. They sincerely want you to succeed, and that can make all the difference. They are part of your team, and to me, that makes all the difference in the long run. They truly are a partner, not a company working for you.
