"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
Fox 7ef901
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
“Through Toptal, we were able to find and select a senior engineer who is both very professional and easy to work with. The quality of matching that Toptal enabled has been crucial to our success, it was at a fair price, and it came with a much appreciated, risk-reducing trial period.”
John Olsen
Director @ Bingo Solutions
“Robert was such a breath of fresh air! I’m used to working with developers who don’t speak good English, don’t understand my needs, and are bad communicators in general. But Robert was not only an EXCELLENT communicator, he knew exactly what I was looking for and made it better than I thought possible. Now I have a website that works better than I thought it could for less than the cost it would have taken other developers, and in half the time. Robert is as good as they come, and a true professional. Anyone thinking of working with him, stop thinking about it and hire him. You won’t regret it.”
Matthew Bennett
CEO @ Winning Social
“Back in July '12, 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
“Toptal makes finding qualified engineers a breeze. We needed an experience ASP.NET MVC architect to guide the development of our start-up app, and Toptal had three great candidates for us in less than a week. After making our selection, the engineer was online immediately and hit the ground running. It was so much faster and easier than having to discover and vet candidates ourselves.”
Jeff Kelly
Co-Founder @ Concerted Solutions
“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
“Getting set up with Toptal and finding a new team member was so easy, I don't know why anyone wouldn't give it a try. Best of all, we no longer have to worry about finding great people to help with our projects!”
Mike Branch
President & CTO @ HarborSI
“We were extremely impressed with both Toptal and our developer, Bojan. They were extremely professional and flexible with our schedule. On multiple occasions, we needed to alter our timeline and they never hesitated to accommodate us. Bojan was communicative and delivered what we asked for on time and exactly to spec. I know that should we need additional work, will surely be looking to hire Bojan and Toptal again. ”
Stephen Vasallo
Co-founder @ Bubble
“Toptal has helped my business tremendously by finding, vetting, and recruiting the talent I need, at the right time. I’d definitely recommend it to others.”
Xavier Xicay
CEO & Creative Director @ Tuatara Corp
“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
“One of their engineers from Colombia has joined our team as a full-time developer for more than 6 months, sometimes flying to work on-site in New York City with us. He is one of the best developers I've ever worked with.”
Carter Cleveland
CEO @ Artsy
“It has been wonderful to work with Fabian for the past two years. He is an expert in JavaScript development and has built our embeddable widget and video player. He is a quick study and is able to learn how to integrate new technologies, which is so critical for a startup. He even took the extra effort to teach others on the team. He is super responsive and often went above and beyond to help us meet deadlines (including working on weekends). Thank you Fabian. Thank you Toptal for making it so easy to find and work with amazing talent.”
Natasha Mohanty
“Working with Toptal has been a great experience. Prior to using them, I had spent quite some time interviewing other freelancers and wasn't finding what I needed. After engaging with Toptal, they matched me up with the perfect developer in a matter of days. Amaury, the developer I'm working with, had all of the right skills and experiences that I needed for my project. He not only delivers quality code, but he also makes suggestions on things that I hadn't thought of. It's clear to me that Amaury knows what he is doing and I'm happy to have him on the team. Highly recommended!”
George Cheng
CEO @ Bulavard, Inc.
“We really enjoy working with Toptal. The experience has been very positive, and we'd recommend it to anyone seeking developers on-demand.”
