Investing in companies with no revenue, incidental interest

Assalamu Alaikum,

Is it okay to invest in companies that are early-stage and have little to no actual sales/revenue from their main business yet, and as a result the revenue may just be interest from cash in the bank until they advance their product? Biotech and early-stage mining companies can fall into this category - Moderna is one example.

JazakAllah khair


May Allah bless you.
The issue would be, if they are using the interest earned, then you have to ensure that you cleanse your revenues.
Secondly, once they start to operate then to monitor that their operations are still shariah compliant.

And Allah knows best!
