Hey {{first_name}},
I just wanted to touch base and say hello, and see how things are going in the meantime?
Last time we chatted, you agreed to get back in touch with you if I come across any opportunities that might be a good fit for your company.
If there's anything that I can help with or provide some valuable information on our product, then let me know - it would be great to hear from you!
Thank you again for taking time out of your busy schedule last week to have a chat. I really appreciate it.
Best wishes,
[[your name]]
