I talk to founding AEs every week. The same question comes up in almost every conversation: how do I know if this startup is worth joining?
They ask about ARR. They ask about funding. They ask about the product.
Those things matter. But they're not the thing I look for first.
Internal vs. External
When I evaluate a company for a founding AE, the first thing I want to know is whether the founder is internal or external.
Internal founders are heads-down. Building. Focused on what's happening inside their own org. Shipping features. Talking to engineers. Optimizing the product.
External founders are in front of customers. Leveraging their personal network. Working the board for introductions. Putting a perspective out there on LinkedIn. Creating pull.
Both can build great companies. Only one creates the conditions where a founding AE can succeed.
Why This Matters More Than You Think
Early-stage companies almost never have a marketing function that's humming. There's no demand gen engine. No brand awareness. No inbound machine.
So if the founder isn't out front, leveraging introductions from their personal network, leveraging introductions from the board to help drive momentum, guess who has to do all of that?
You.
And you're doing it with no wind at your back.
That's the difference between a founding AE role where you're building on momentum and one where you're generating all of it yourself. Same title. Completely different jobs.
How to Read the Signals
Before you accept an offer, spend 10 minutes on the founder's LinkedIn. You're looking for a few things:
Are they visible? Do they post? Do they have a following? Are people engaging with their content?
Are they strategic or tactical? Is their content about where the market is going, or is it feature-driven? "We just shipped X" is tactical. "Here's why the industry is shifting toward Y" is strategic. You want to work for the second founder.
Are they a sales exec or something else? Look at their background. "VP of Sales and Marketing" or "Director of Sales and Success" tells you something. You're either a sales exec or you're not. When the title starts collecting functions, that's a data point.
None of these are dealbreakers on their own. They're data points. But they tell you what kind of founder you'd be working for and how much of the go-to-market burden falls on you.
The Customer Reference Test
Here's the move most candidates skip: before you accept, ask to talk to a customer.
Do it through the company. Say: "Before I move forward, I'd love to talk to a customer."
If they say yes, great. You'll learn more in that conversation than in three interviews.
If they say no, that tells you something too. Either they don't have a customer who's happy enough, or they don't have a relationship that's strong enough. Both are worth knowing before you sign.
Some companies will push back. "We can't have every candidate doing that." Fine. But you're not every candidate. You're probably one of two or three people they're making an offer to. This is a big decision. They should want you to feel confident.
The Questions That Actually Matter
Once you're past the LinkedIn check and the customer reference, here's what to dig into:
What are the real risks to the business? Not the pitch. The risks. If the founder can't name them, that's a problem.
What does success look like beyond selling? Are you the pipeline builder? Are you closing deals that already exist? What's the actual job, specifically?
Where are the gaps? Every founder will give you the best version. Ask about the gaps. Ask about the customer who churned. Ask what that team was hoping to get that they didn't get, and whether the problem has been fixed.
The Bottom Line
The founding AE role is one of the best jobs in tech. You get to build something from zero. You get equity. You get to shape how a company sells.
But the wrong founding AE role will burn you out in six months. And the difference between the right one and the wrong one usually comes down to one thing: is the founder creating pull, or are you doing it alone?
Spend 10 minutes on LinkedIn before you spend 10 months finding out.
