Its a tough time to close a new funding round. Not knowing what type of investor you were talking too I would suggest you need to
1) update your pitch deck (and if necessary your business model) to show how your products will be more relevant in the post Covid new world we will live in – including support from your distribution partners
2) Make a list of other types of funders you could approach and who are still investing ( I am not pretending this will be easy – it wont)
