“We want to outsource one product development part, we were not looking for freelancers, already burnt our hand on freelancers. I checked the platform, contacted a couple of teams, good curation is done, we decided to go with one. Highly recommended, this is 10X better than other freelance platforms available in the market, with no commission."
