Insights are extremely important and should always be an input into your messaging architecture or recommendation. Market and customer insights are one of the best ways to make a case for your recommendation, in fact.
So you don't get stuck in an analysis paralysis state, I'd do a quick audit to understand the current state of data and insights as it pertains to your product/market/etc. Find out:
- What research is complete and available? This could be something like a survey to your database that was run in the past, research you paid for, data and analysis from things like a TAM anaylsis, investor/board meetings, etc.
- Where do you think the biggest gaps are that research would help you fill? Is that gap something qualitative or quantitative research could help you figure out. One example of this is understanding key performance motivators of a persona - you would probably get way more talking to 5 to 10 people live vs looking at quantitaive data here.
- How much time do you have? Again you don't want to be stuck in analaysis for months and there are ways to accomplish developing these types of insights thoroughly or quickly.
From there, you can put a quick research plan together as part of your larger messaging project plan. Try tapping those in your company who've been there a while, have that tribal knowledge, as they may know where to point you for previously completed research and what customers/prospects to talk to.
