When folks at Handmade in Britain were looking to build a platform for artists & designers to sell their artwork masterpieces online, they approached Reliqus with a vision to build a successful business.

With more than 150 artists and a catalog of 10k+ products, they now have one of the fastest growing online marketplaces in the United Kingdom.

Challenging the market leaders was tough, but not impossible. That is exactly what Reliqus did for Victory Cinema.

Working with Ankit and his team was a breath of fresh air. The communication was easy and often. With times where he checked in on me to make sure we were staying on path. The over quality of the work was some of the best you can find out there. Everyone has been impressed with the job that was done...

Ankit's team are top notch - very high quality work, and if changes are requested they only need to be asked once which has not been the case with other freelancers! If you're thinking about hiring Ankit, do it, you won't regret it.
