Initialized Capital is a San Francisco-based VC firm with over $500M under management. We're founders and builders who are here to help others like us build meaningful businesses. We focus on investing in high-potential software startups at seed stage and earlier, and are happy to be the first investors in early teams run by great engineers, designers and product founders. We've helped more founders build startups at the earliest possible stage than most anyone you'll meet, and that means we can help startups avoid the 1,000 landmines that can cause certain failure. It certainly won't guarantee success (as we all know there's no such thing in startups) but at the seed stage we've seen many cases where having the right investors will improve your chances significantly. In the end, we started this firm to help people like ourselves build companies that matter. A lot of great investors, advisors, founders, and friends have helped us along the way. We're just here to pay it forward.

Bullpen Capital invests in post-seed companies that have achieved product-market fit, but have not yet proven sufficient market scalability to raise a major VC round.  We invest in companies that have an operational plan to hit big milestones within a 12-month period, and we work closely with the companies in our portfolio to develop this early traction into large, sustainable businesses. Seed financing is now more of a process than an event, with multiple rounds of investment layered into the early stages of startup companies.  The "post-seed" stage is often the inflection point of value, the last lean money in before a “super-sized” A round.  Bullpen’s strategy aims to provide leverage for founding teams, who can minimize dilution to maintain ownership and control of their companies, while retaining the option of choosing either a quick acquisition or raising major growth capital to go for a big win.
