This process was mandatory at my last company, and it was really helpful. People are way more likely to respond to your email or do something for you as a newer employee if they've met you, particularly so if you can meet in person. Taking notes during or immediately after the meeting, then synthesizing them to form a narrative is also helpful when you're meeting so many people. The other thing I do is start a file literally titled "Everything I know about <company>" and just write everything down. I make diagrams, write sentences with highlighted blank spaces for gaps in knowledge, etc. As you get to the 10th meeting, you have a decent mental model of how things are intended to work, and have probably heard about some of the systems the 11th person works with. When you communicate some of your understanding of the system to them, they can fill in gaps or correct misunderstandings. The other thing I always ask about is what a cadence or work looks like? Is there seasonality in their availability? Finance/accounting are best left alone the first week of the month as they're dealing with month end. Some people are slammed Monday and Tuesday, catching up from things that happened over the weekend. If an entire business is seasonal, it makes sense to prioritize heavy lift projects to the off-season.
