About Birchmere Ventures
Across five funds and two decades, we've helped build numerous successful companies such as Cvent (event management - IPO) , TenMarks (math tutoring - acquired by Amazon) CyOptics (optical chips - acquired by Avago), Neolinear (EDA - acquired by Cadence), and FreeMarkets (B2B marketplace - IPO). We believe great companies can start anywhere (but to scale quickly they may require a coastal presence), and the best engineers and scientists do not go to just a few schools on each coast. These core principles lead us to invest in companies from across the country overlooked by many other investors, uncovering hidden gems and helping them scale up.
