How many of you started a business during the pandemic?

Hi, I lost my job in this pandemic, So I am also thinking about starting a new business and I am thinking about to making a business plan. If you know any best site regarding this then please let me know. I hope I will find it soon.

We were working on something before the pandemic. It was a social eating app for campuses. When the pandemic happened we actually had to pivot to our current product (Between).
