Social engineering - scope out their support forums, their annual reports, media releases.

Identify as many customers of theirs as possible in a few days, then start making notes on those customers; size, people that post in tech | social forums, their media releases.

Follow up with cold calling | DM's via socials etc. to ask about experiences with { problem domain | bigger supply company | software } etc.

It's a hard one to lay out in advance, the path forward will often reveal itself as you scope out more and more.
