I'm not so sure about that, one the typical characteristics of even mild hypomania, impulsivity, is clearly incompatible with long term endeavors. I've seen papers saying that very mild chronic depression might be associated with professional success, not sure how well they'll hold up.
From the five factor point of view, as far as I understand there is some evidence that high openness to new experience (for new ventures), high conscientiousness, below average agreeableness along with high IQ are strongly correlated with success. Not so much for neuroticism and extraversion, though the latter probably helps in some specific jobs (but surprisingly, not necessarily sales).
I'm fairly sure I know someone who's unipolar BP type II, and while sometimes they can be very depressed or fatigued, the vast majority of the time they have absolutely mind boggling stamina for challenge. They constantly read, think, plan, experiment, and just get stuff done. When combined with a work ethic and intelligence, they manage to somehow pull off remarkable feats on a daily basis. It's not at all surprising to consider that they'd be extremely successful at starting a business, if that was what they chose to do.
They're almost like the guy from Limitless, when they put their mind to something it just happens like magic. Of course, they rarely stay focused on anything for too long, so starting a business they'd likely feel too trapped. They're always eyeing the exits, because they're so restless and need freedom like we need air.
This makes sense to me, every change from the average comes with corresponding pros and cons. The same traits in an office that make someone successful in business might not translate to a survival situation, etc.
In their case, I'd say it mostly comes out in the wash. They do decently well at work, but don't commit well to bigger projects, and they don't finish projects well.
What you allude to is not really mania or hypomania. It's just having a lot of energy and focus. Manic people have a lot of energy for sure, but it's defined by its harmful consequences. They drive too fast, they sleep too little, they talk too much and keep interrupting people, they have sexual urges that are as strong as they're inappropriate.
Take this older lady I knew of who, when she was stopped by a traffic cop for speeding, was absolutely convinced he was just hitting on her. Seriously. Or that guy I knew personally who squandered his sizable inheritance within just a couple years on ... escorts. I don't know the exact numbers but it was over a million €.
The family I referenced earlier struck me as subclinically hypomanic not because they had lots of energy, but because they approached the limits of harmful behavior.
