How are you going to keep your business afloat during the pandemic?

I just started on my project. I'm in the stage of marketing but it's pretty tough...

on the laptop, make more sales

It all depend on your target market.
As basically, whole economy segments are collapsed in a matter of days, so there are no such markets anymore for a while.

To help people ask easily money on these days where getting out is more and more difficult, with some friends we are putting together an app that will ease money asking.

Most of the companies have started work from home.

Immediately ask all my employees to stop coming to work and conduct an online internal seminar briefing the situation and how we all can tackle it together:-
Give a little Personal touch:

• Brief on not to Panic, but be Responsible.
• Work comes later, Health comes first.
• If there's no employee left to live, what good coming to work would do.

Then, Sprinkle a little business in there. Our little biz family would now willingly support WFH until and unless this all is resolved. We would then dive deeper into it once the root has been set and mutually agreed upon by every single soul that it's the right thing to do.

This is just a fraction of what more should be done but I think panicking is the one thing we should get off of all people, and instead teach them some strategical approach to tackle the pandemic. Good luck

I launched a product just as things became particularly bad with the pandemic.

We're re-evaluating which sub-markets within our broader target market are best to talk to right now — we're hoping Covid craziness has flipped things around such that our product is suddenly relevant where it previously wasn't.

Hey Leo ! Hope all is fine for you. On our side, we work hard on our community growing, talk to them answer them (best thing to do in my opinion) and also on our blog section to keep our service working during this hard period.
Hope it can help you a bit

Keep calm and carry on!
