"Toptal is killing it, it kind of owns this market."
Andrew Ross Sorkin Reviews Toptal
Cnbc 02e66b
"Tech companies simply cannot find the quality employees they want to hire. The solution: Toptal."
Liz Claman´s Review of Toptal

Toptal in the press
“Despite accelerating demand for coders, Toptal prides itself on almost Ivy League-level vetting.”
Selina Wang
“Toptal allows corporations to quickly assemble teams that have the right skills for specific projects.”
Steven Norton
Testimonials
“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
“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
“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
“Andrea is doing an amazing job. I don't think we could have gotten a better person. He is fun to work with, he thinks out of the box, and he is extremely knowledgeable in what he is going. He not only does an excellent job, he also helps our company to differentiate our business model further (e.g. making our app offline-capable). I would recommend Andrea as well as Toptal any time to any friend.”
Pascal Girardat
Co-Founder / CEO @ Lifestage Solutions AG
“We needed a talented developer and we needed him/her very quickly. So we turned to Toptal and couldn't be happier with the results! 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
Founder & Owner @ FairTech Labs, LLC
“Toptal developers deliver. Hiring my first developer on Toptal was such a pleasant experience that I quickly turned around and hired another. Every developer I've hired on Toptal has been professional, skilled, and self-managing—a pleasant departure from the typical freelancer marketplace.”
Mike Riess
Owner @ RiessGroup
“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.”
Bruno De Martino
