## About

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.

## Questions

### Who runs investment decisions at Sigma Partners?

Current investment decisions are led by Managing Directors Greg Gretsch and Wade Woodson. Gretsch joined the firm in the early 2000s and has been a public face of the partnership's enterprise software strategy. The firm operates with a small, consensus-driven senior team typical of a focused early-stage venture partnership.

### How does Sigma Partners differentiate from other early-stage enterprise VCs?

Operational longevity — founded in 1984 — combined with an unchanged enterprise mandate gives Sigma a peer set that is remarkably small. The firm has avoided launching growth, crypto, or international funds. For a limited partner, this represents an explicit, uninterrupted bet on early enterprise software that few other Sand Hill Road-era firms have maintained without dilution.
