Is it true?
Is it because investors are not willing to invest in any "hard" businesses?
So far, nothing really changed for us at Reliza (https://reliza.io). My plan for this year was to launch MVP and work on it, which we did late February, and then work on it. Regarding funding, we were planning to look into raising funds towards the end of the year - early 2021.
It currently does not look like there is more activity from investors, on the contrary feels like raising money is harder unless your project directly relates to something that may be used to tackle the pandemic.
So for us it just means we should be prepared to defer possible funding round for later. I'm afraid, for many startups this time would be extremely challenging, especially if pandemic lasts for many months.
