Warm intros are great, but not necessary.
Just email over the pitch and the deck. Send as much detail as possible, including metrics. Make the email + deck stand on its own. And if you have less than 10 Unaffiliated Customers — it’s too early. It’s also probably too early if you have less than about $8k-$10k in MRR (not always, but usually).
I cannot respond to every email — apologies in advance. It’s 1000s.
But unless I am traveling, etc. I do read almost all of them.
