Of course you can't make a judgement. Without a trade deal no Company would move to the UK. Now the future is more certain a more informed judgement can be made. That is so obvious your original question asking what companies have moved here since Brexit, in order to form a judgement, is absurd. Brexit can't be determined by what has happened in the last 4 years. Perhaps in the next 4 years we will have a better idea whether Brexit is a success or failure.
