If you have to rely on any conference to gain traction you are in deep trouble. Make sure you have a solid business that can execute with as little external dependencies as possible. Launch on your results and accomplishments, not just stories and promises. People who attend these conferences are suffering from information overload. Prove something and you'll get a chance to stand out from the crowd. Generally you'll get way better treatment if you make them want to be part of your success, rather than be a supplicant desperate for a lifeline.
