    • Si Muddell
      Si Muddell Review from Google
      4.0 ★

      Si Muddell's Review Sourced from Google

      Fantastically positive and driven team who on every interaction you just know care deeply about a) what they do b) what they deliver and c) ultimately the experience the end user will have. Hugely impressed with their personal, creative and energy driven approach at the pitch stage, I commissioned 3SC to help us better scope an app. Their task was to take an in-house developed app prototype, and turn it into a fully fledged technical specification with user stories, MoSCoW prioritisation, costs, and an updated look and feel; all done with audience need at the heart. Myself and the wider team have nothing but very good things to say about 3SC. When reflecting on an agency to work with, loads say they can do it, some can actually do what they say they can do, even less do it in the spirit of real partnership and mutually respect/drive. 3SC do all of these excellently. I highly recommend them.
