Our Toptal freelancer has contributed extraordinary knowledge, talent, and startup experience to our team. We will continue to work with Toptal to fulfill our future talent needs.”
Lindsay Fairman

Alex Haro
CEO @ Life360
“We've had multiple needs for various development talent and Toptal doesn't disappoint. They truly focus on matching the best developer to our specific engagements, and they continue to stay connected in an effort to exceed our expectations at all times”
Mindle Hastings
Sr. Product Manager @ Bodybuilding.com
“We're a small firm with big dreams. After trying 4 or 5 local or outsourced developers, we were out of options. I'd heard of Toptal, but was worried that my company wasn't big enough for them. After calling them up, I found out that I didn't need to meet any minimum budget and was immediately put in touch with a developer to talk through my problems and goals. A day later, he got back to me with a list of possible solutions. After 9 months and 5 developers, Toptal got me my solution in a single week at a price I could afford.”
Kevin Ramirez
Co-Founder @ SixtyVocab.com
“My business relationship with Toptal has been nothing short of terrific. From reviewing my project with their team to choosing a highly-talented developer, and all the way through releasing our application, it has been an incredibly smooth and successful experience.”
Gary Craig
Senior Analyst @ NetApp
“When you're growing quickly and your internal resources are strapped, you need to find a way to move forward regardless. We couldn't have done it without Toptal. 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.”
Josh Leskar
Manager @ Udemy
“We struggled for weeks to find a developer or architect with expertise in a niche API, but to no avail. When we linked up with Toptal, they connected us with the very expert we needed, and a week later we were hard at work making progress! The whole process was very smooth and we ended up with a new feature we couldn't have done without Toptal.”
Thomas Honeyman
COO @ FindMySong
“FundedByMe needed to quickly scale our development team to create the equity crowdfunding leg of our operation. Working with a small budget, we couldn't spend time on vetting candidates, so we turned to Toptal. They identified a stellar developer that truly set the bar when it came to delivering product.”
Arno Smit
CTO @ FundedByMe.com
“My experience with Toptal has exceeded expectations. I needed to quickly find a front-end developer, and the first person they recommended was a perfect fit. A month later, I needed an iOS developer and they delivered again. I'm incredibly impressed with the quality of the people in Toptal's network and how quickly I was able to find a match for my needs.”

Jeff Kerr
CEO @ CaseFleet
“We have been incredibly happy with our Toptal experience. Initially a skeptic, the process to find and recruit a fabulous iOS developer was very easy. Rather than sifting through hundreds of CVs, we saw two and hired them. They have worked effectively, getting up to speed incredibly quickly and have almost become part of the team. We would definitely use Toptal again. ”
James O'Day
Co-Founder @ Pearlshare
