If your SaaS is good, that's no way different than selling a standard B2B service on LinkedIn!
In today's (detailed) video I go through the exact steps you'd need to take in order to get that taken care of.
I also use a highly specific example from the golf industry as well as an exact example of a DM conversation I had with someone working in a SaaS at the time.
This video along is like the only thing you need to get those B2B SaaS sales with predictability, so watch it - it's THAT good!!!
