How to find success as a Founding AE?

Happy Holidays savages.

I've landed a founding AE role at a seed startup and looking for advice from leaders/founders that have hired founding sales roles.

What did failed FAEs do?

and

What did the successful ones do?

For context:

• They have not been explicit around expectations.
• Only thing that they have touched on is that their inbound is too much to handle right now and they want me to focus on closing deals.
• No actual quota but obvi making commish.
• Inbound is extremely healthy and they are growing at an alarming rate so outbound is not a priority but they want it to be something we explore soon-ish.
• Founder and a Head of Sales have been doing all the selling.
• There is almost nothing built out. The resources available are old or not useful docs in a drive.
• This is a damn good product and literally nothing like it exists at the moment - not a complex sell at all but it fixes a huge problem.
• Team is super smart and have built an amazing product with great success in such short time but my sales IQ is well beyond theirs.
• 1 week in.

What I've been doing:

• Already taking calls/demos.
• Building out all the sales resources from scratch in a new knowledge base: Discovery framework, calling framework, sequences, competitor battlecards, docs, decks, inbound/outbound motion.
• Providing direct feedback to product and leadership.

If you've been a FAE or Leader/Founder that have hired one, would love to hear your stories and advice. I don't ever want to feel for a second that I am not doing enough. Can't thank ya'll enough.
