Why Clients trust Contra
The quality of independents on Contra is top-notch, and the onboarding process is one to model. Being able to speak with a team member to truly understand what we needed as well as offer suggestions of talent in the network was a whole new experience for me.
Love, love, love. Contra is an amazing place to find flexible, creative talent. The process of getting to know independents through their profiles was incredibly easy and fast.
The talent I find on Contra has been excellent. But aside from that, Contra’s community differentiates Contra from other freelancing platforms. I love the responsiveness of the Contra team, and how invested they are in your success. I actually pay freelancers I’ve found outside of Contra through Contra because I love the platform so much, especially that they don’t take a cut of your payment.
I used to waste hours trying to find talent. Switching to Contra was 10x on my time, energy and money as an Entrepeneur and Creator. Lauren was a perfect fit from day one, and I couldn’t have found someone of this calibor without Contra.
I can vouch for Contra that it is a great hiring tool. I shoot my shot and the candidates I keep seeing are incredible.The process took minutes and the support I always get from their team is 10/10.
Freelancers on Contra come across very professionally. They actually seem to read your job posting and have directly relevant skills, which isn’t always the case on most other freelancer sites. On Contra, freelancers who matched with my job seemed to have the relevant skills I was seeking.
