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
“John has been so great to work with! He has met all our requirements, done a speedy job with excellence, and has completed everything we’ve asked him to. Working with him has been a great experience.”
Jenny Lord
Communications Project Manager @ Lake Pointe Church
“We had a great experience with Toptal. They paired us with the perfect developer for our application and made the process very easy. It was also easy to extend beyond the initial time frame, and we were able to keep the same contractor throughout our project. We definitely recommend Toptal for finding high quality talent quickly and seamlessly.”
Ryan Morrissey
CTO @ Applied Business Technologies, LLC
“I’m a big believer in the saying, ‘hire smart, or manage tough’. For us non-hackers, Toptal takes the guesswork out of hiring. Their coders are vetted, and the work is guaranteed. Why look anywhere else?”
Greg Archbald
Founder & CEO @ Greasebook
“Toptal is amazing. Sourcing and interviewing candidates has always been incredibly cumbersome and difficult - and usually takes weeks or months to find the right people. With Toptal, we had 5 candidates in 2 days that were all perfect for the job. They made the scheduling of interviews easy and straightforward and we were working with a top-level developer within 2 weeks. I love you, Toptal.”
Ian Fosbery
CTO @ NMRKT
“In our 2 years of operations this is by far the most enjoyable and productive working relationship we have had with a developer. I plan on continuing to recommend Toptal's services to other entrepreneurs I run into.”
David Sawyer
CEO @ TSOLife
“We needed a programmer to help push a project over the finish line, and I figured -- best case -- Toptal would find someone who would come in and complete a few tickets. Instead, Sergio blended right in with the team and made significant progress after mere days of ramp-up. He even offered to take his laptop with him on vacation in case we had a customer issue with his code! He surpassed my expectations, and then some.”
Bryan Adams
CTO @ Healthsense
“The developers I was paired with were incredible -- smart, driven, and responsive. It used to be hard to find quality engineers and consultants. Now it isn't.”
Ryan Rockefeller
CEO @ Radeeus
“I'm incredibly impressed with the caliber of the Toptal developers I have worked with - they have proven themselves to be both dedicated and highly talented. We will most definitely continue to work with Toptal. ”
Savannah de Savary
Founder @ Industry Hub
“Toptal is a great resource for startups with ever-changing product roadmaps and budgets. Within 8 business days of our first conversation, we had highly skilled and reasonably priced Toptal developers working for us. It has been an empowering experience for our company to start working with Toptal.”
Chris Clark
CEO @ BirdieFire
“Sergio was an awesome developer to work with. Top notch, responsive, and got the work done efficiently.”
Dennis Baldwin
Chief Technologist and Co-Founder @ PriceBlink
“I needed help, and fast. I did not want to hire a random coder I met online- I was worried about security, and many other issues. Toptal was there when I needed them- and has been fantastic to work with. Outsourcing is full of terrible stories- Toptal is the story that is the giant exception. I give them my highest recommendation.”
Michael Feder
Founder & CEO @ PrayerSpark
“Toptal helped us when we had a hiring gap we needed to fill. The developer we received was excellent, with a great work ethic and fit in very well with the team. We are very happy with the service and would definitely consider using Toptal again in future should we need additional help. ”
David Gildeh
CEO @ Dataloop.io
“One of our most time consuming problems is finding qualified staff. We need to find the correct platform to advertise on, create a proper ad, filter through tons of applications, interview and test the applicants' capabilities, and finally take a risk by hiring. This was the old way of doing things. The new way: describe the job position to our Toptal account manager, interview a few qualified applicants, and hire with a risk-free trial -- much faster, a lot easier, and with incredible results.”
Catalin S. Balaci
Owner @ EvoBits Information Technology SRL
“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
