I'm the co-founder of a two-person startup, but I'm having a hard time coming up with an accurate description of my job for things like LinkedIn and business cards.
I handle all technical aspects of the company, so something like "Co-Founder and CTO" or "Co-Founder and Technical Lead" would certainly cover it, but I feel like those titles are somewhat pretentious, as I don't manage anyone. I don't want to seem like I'm trying to inflate my title, but I do want to convey that I'm making the technical decisions for the company.
So, what's a good job title for someone who co-founded a startup with no non-founder employees, who handles all technical decisions but doesn't manage anyone?
