“Dario was recently assigned to our company in order to help with PHP and JW Video player refinements. He listens extremely well and offers common sense suggestions that save both time and money. He speeds up the process by asking great questions, and he just delivered our first project on time. His redesigned player offers a very pleasing appearance and delivers functions that are both elegant and intuitive.”

Alex Haro
CEO @ Life360
“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
Head of Product @ Token

“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

“We have been with Toptal for over two years and have hired through them multiple times. They've never failed to deliver with world-class talent and customer service and have been our first choice when scaling our team.”
Stuart Reavley
Product Lead @ ClassDojo
“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 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
“Always incredibly responsive, prompt, and flexible, Anna has done an outstanding job -- her work is exactly what we needed. Toptal has been a great experience for us due to the ease of getting a project going with quality talent at a cost that fits our budget. The automated online system for managing everything during onboarding was also impressive.”
