About Sigma Partners

Sigma Partners was founded in 1984 on the principle that people are the essential element of success. That is why Sigma focuses on identifying exceptional entrepreneurs with creative ideas and supporting them in building great companies.

Unlike some firms that hire venture capitalists based upon their business school degrees and finance backgrounds, we think it's much more important to have partners with experience in the trenches starting and running entrepreneurial companies. This first-hand experience allows us to give early-stage companies both tactical and strategic guidance and access to a powerful business network. We work on behalf of our portfolio companies. We know business doesn't always go as planned, but because we've invested in the best and brightest entrepreneurs, together we adapt and create success.

Our investment track record is proof. For over two decades Sigma Partners has invested in over a hundred early stage companies, and our portfolio has consistently outperformed. In 2007, we raised $500 million for Sigma Partners 8, bringing our total capital under management to over $2 billion. We continue to invest today in the same way we have since our inception, by identifying great entrepreneurs and collaborating with them to build strong businesses.
