Do you think it is feasible to work on two startups at once? And I'm not talking about being hired at one startup and doing something on the side, I mean two full-time startups where you are one of the founders.
Personally, I wouldn't but yes it is possible as you said - Steve Jobs did it and Jack Dorsey does it.
However, this doesn't mean that you are Steve Jobs/Jack Dorsey and running two startups at once is hard work. Especially when, most people can't even run one!
There are tons of people's opinions regarding this for instance:
FWIW: I'm not putting Steve Jobs or Jack Dorsey in the same boat, I'm just highlighting someone else who currently does it. (Nor am I discreditting Jack Dorsey by saying this - Square and Twitter are both great startups)
It's possible, but I'd avoid it. I bootstrapped a startup while employed at a large (~500 person) company and let the company go in the wrong direction too long because of it. Later I joined a startup where the CEO was still employed at a company he'd founded previously. I don't think either company failed solely because of the other commitments, but we will never know what opportunities were missed because of them.
