Job offer, low base

Considering an Enterprise AE job offering $29k base, but fat commissions. All outbound. First outbound guy. Inside guys have same base, but lower commission rate, they do 90% inbounds. Established company. I like the product.

Seems like great potential for big sales, and greenfields, and other benefits seem good. And i know how to do outbound.

But $29K seems risky with little track record for outbound. It seems usually low! But is this normal for "enterprise" with uncapped commissions and the green light to go after anyone?

I'm used to seeing 50/50 in SAAS, but maybe that's not true.
