Meeting with a VC today, what do I do? (I will not promote)

For context, I secured a 30 minute meeting with a very well decorated VC partner in my industry (cybersecurity). The email chain we had was pretty vague, but I'm under the impression that this is a VC meeting where I need to impress them and get a follow-up meeting. This is the first VC meeting I've ever done, so I just want to know any tips (specific non-obvious things to mention, metrics I should have prepared, anything that would potentially trip me up) from people who have already experienced this and successfully gotten that second meeting. Thanks a lot!
