Mindle Hastings
Sr. Product Manager @ Bodybuilding.com
“Toptal was the best thing to happen to my web app. Initially, I hired a team of freelancers from India through another freelancing website—which was a nightmare. In fact, it was so bad that I had to start again from scratch, which is when I found Toptal. The experiences were like night and day. It was so refreshing to get partnered up with a quality developer that I could trust due to Toptal's extensive screening process. I will only use Toptal from now on and highly recommend you do the same.”
Chris Holtzhauer
CEO @ HootRecruit

From content creation to programming and design, we were able to leverage the expertise of Toptal's network to move even faster that we could have otherwise. They prioritized finding us the right person, not just a person. Every single one they introduced us to was not only qualified and professional, but also eager to help us.”
