Our focus is generally on early-stage, East Coast, and enterprise software, especially virtual infrastructure andcloud-based solutions. We prefer technology risk to market risk, and won't generally invest in 100% consumer-facing businesses.We get that great teams are built over time, but typically look for a core team (at least 2 people) that includes a technologist with experience building solutions similar to the one being proposed, and a business person who really understands the buyer and how to reach them. We like to see a product in market, and some early customer validation. Our sweet spot investment is $2-5 million in Series A. We reserve capital for every earlier stage deal we do, meaning we want to be with you all the way.
