TechMap is a community-oriented project bringing together people who work within the technology startup universe. We organize meetups to bring together co-founders, talent, and investors. You are working within the startup ecosystem and wondering what opportunities are out there? You work a corporate job and want to feel the excitement of being part of a vibrant innovative young venture? Or perhaps you are interested in investing as an angel, venture capitalists, or pursuing a technology acquisition? Or perhaps you have an idea yourself and dream of becoming a tech entrepreneur. Then the TechMap is your landing page to find out more. What makes TechMap different is that we are purely focused on startups, the stages between idea conception to maturity and exit – the timeframe where excitement, agility, and delivering running code still dominates. Think the dot-com days.
