If you want to learn more about the real story behind mashups, APIs and tools -- the good, bad and the ugly -- you're in luck. Today we're introducing a new feature on the site: the ProgrammableWeb Case Studies. In this ongoing series we'll be going behind the scenes of the programmable web by talking with mashup developers, API providers, tool vendors, and other notable players in this ecosystem. Over time this collected knowledgebase of experience can hopefully help us all get a better understanding of who's doing what, what's working, what are the viable business models, what are the technology tips-and-tricks, and finally, we might pick-up some good anecdotes along the way. Our first interview is with Matt Douglas, CEO of MyPunchbowl, a Boston-based startup focused on event and party planning. As part of their service they integrate a variety of third-party APIs for things ranging from mapping to contacts to media management. 1. What is MyPunchbowl and why did you start the company? MyPunchbowl.com is a new web application for event and party planning. It features an easy to use interface and tools for every step in the lifecycle of a party. We built MyPunchbowl because we didn't like the current products on the market, and we had a vision for a product that would help a user with every step of party planning. Fundamentally, we built the product for us. And we hope our customers love it too.
