I'm 23 as well, co/founded a few startups now. I never tell people my age - ageism is a real thing and sets in the second they identify you as someone young enough to be "inexperienced" even if you are far from it. When I don't tell people my age, they generally assume I'm late 20's to early 30's, which allows me to command more seniority and respect from my coworkers. Your youthfulness is your most valuable weapon. It also makes you a risk. There are two types of companies - those that will seek to mitigate that risk or not get involved altogether. And those that will recognize that with great risk comes great reward.
