ISVCon is a conference for ISVs to get together, learn and grow. It's ISVs sharing their knowledge. Learning from one another. Meeting new people. It's people helping you with the things you may not know, or aren't very good at (yet).
The speakers at ISVCon are other ISVs, or people who work with them. They have done it themselves, have had others help them, still get help from others - and help others in return.
Come to ISVCon and hang out with these ISVs (and some newbies too). ISVCon includes people who have been in business for years, people who are just starting out, people who are full-time ISVs, people who work for someone else and run their business on the side - all varieties of ISVs.
