This is a celebration of TechCrunch's 5th anniversary, with over 300 meetups taking place around the world, featuring sponsors such as IMVU, Mashery, Charles River Ventures, and others, who support the community by providing resources like API marketplaces, tracking tools, and developer documentation. The event aims to bring together entrepreneurs, developers, and small business owners to connect, share knowledge, and build relationships. TechCrunch is grateful for the help of Rob Ross in organizing the San Francisco event, which promises to be one of the largest celebrations. The company's portfolio includes successful startups like Blippy, Yammer, and Zendesk, and provides resources such as Twilio's developer community hub, API reference documentation, and industry reports.
