Bit of a random question.I’m curious if there are there any other ASX companies that are pre-revenue but with a very large market cap. In trying to understand how rare it is for an Australian company to achieve what race is trying to do. I know the RAC plan is extremely ambitious, and if they reach some of the buyout predictions here, it will probably be way beyond anything before. But it would still be good to know if there are any other vaguely comparable Australian stocks that have been successful?There are a couple of tech companies like Weebit and Brainchip that could possibly maybe be huge one day. I’m not fully across either of these companies but my understanding is they are both in the very early days of revenue. I would basically call them both pre-revenue.I think weebit currently has a market cap of around 750 million and brain chip has even even exceeded 1 billion in the past. Are there any other biotechs that have achieved a large market cap before they started generating revenue? I realise this question is massively simplistic but it would be interesting to know more about any other companies that have done anything vaguely similar to what RAC hopes to do.
