SaaS Ventures
VC Fund · Washington, District of Columbia, United States · 6 investments in United States CleanTech startups, 7 in the past 12 months

We are enterprise software experts. We look to co-invest with strong leads, bringing our network of coinvestors and next round investors as well as enterprise software expertise to add value. We see ourselves as partners who can fill out a round quickly and be a positive influence, and non-competitive as we don't lead or take significantstakes in our portfolio companies. We generally write a small check into rounds of $750k-$3M that are mostly full, being low pain-in-the-ass to entrepreneurs compared to relatively high value add. Having been entrepreneurs, we know that's the most important part.While we'll invest anywhere in the US, we love "second tier markets" that can still support major exits but attract relatively less venture funding: Chicago, Toronto, DC, Baltimore, Atlanta, etc etc!
