I suggest you look at interviewing customers within your prospective customer base to understand where their key pain points are so you can quantify these and solve the biggest problems for your customers first.
Think about where these people may be congregating (likely online given COVID19) – where are they finding their information, who are their thought leaders within the industry and get connected to those organizations/individuals to facilitate introductions to prosoects for their opinions.
I’d also suggest that you may want to potentially offer people compensation for giving you an hour or so of their time. Come prepared with a list of questions around exactly what you want to know that will inform your potential pivot.
The key is to be hyper targeted in your questions so you can interview ~5 or so people and pick up themes that can inform an MVP for product/market fit beta testing.
I hope that helps~
