I've launched two SaaS companies without funding and have successfully grown them to multi-million dollar industry leading services. I've built a simple tool we use daily and would like to perhaps sell it on the side.
An online directory that promotes upcoming online events. It allows event producers to list their event in the directory as well as letting people that are interested in them to browse our categories, discover new events, and sign up for newsletters about new upcoming events that they are interested in. Monetization of the service will be achieved though paid listing and sponsorships.
