Dear Prof. Aman,

It was great talking to you at the event last week!

I wanted to ask if you could please share the contact of the person who
dealt with the technical details of your cluster. As I mentioned, we
are  looking to make a similar investment, and it would be really great to
be able to talk to someone who has already dealt with some of the technical
pitfalls.

Secondly, I would be very happy to host you at our company in the future. Please let
me know if that's the case.

Best regards,
David
