First and most importantly is a shift in mentality. You are not a technical cofounder. You are a sales person. It is a pretty big change, one that I didn't adapt well to.
But basically sales is making lots of calls, and asking questions. You will not be doing a lot of talking, but asking questions about their problems. Then you talk and specifically outline why your solution fits their needs. Let them digest it, then ask for the sale. Surprisingly sales people are afraid to ask for that because they don't want to be seen as pushy.
But again you don't need to talk all that much. I've listened to a business partner land a 100k deal and probably did 10 percent of the conversation.
Also practice and expect to be uncomfortable for hundreds of calls.
Edit: if you have a good source of leads and make a lot of calls, get a service like phone burner. It automatically leaves a voicemail for the 95 percent of people you don't get a hold of on the first try. I had a boss that refused to use that service, was making at minimum a quarter million a year and would spend an hour+ every day leaving the same message. Apparently 50 bucks a month was too expensive.
