Yes, we call the 24 perfect souls Tirthankars. The first one for this time cycle is Rishabhdev (Adinath). But he wasn't the founder either. Jainism's belief is far beyond that. A fraction of the vast information one needs to know on Jainism is available on the following link and on Wikipedia as well. A true Jain is not just someone born as a Jain and who does not eat onions, potatoes, carrots etc (anything grown beneath the soil because these vegetables contain innumerable germs thus, innumerable souls) but also one who knows how important Non-Violence is, how important it is to rise above the Material World is, how important it is to know that everything except the soul is perishable, and thus do only good karmas to reach Moksha. One who knows this, will never fight for anything material but rather fight with oneself and resist these tempations. That person will know that human life is gifted to do good deeds, and reach infinite bliss.
