Background
Greg Williams is a Managing Director at DAG Ventures, a Palo Alto–based venture capital firm he joined in 2006. DAG Ventures was founded in 2004 by Tom Goodrich and John Cadeddu, emerging from Duff Ackerman & Goodrich, a private investment firm originally formed in 1991. The firm built its reputation by leading mid-stage and growth financing rounds into promising companies sourced through relationships with select, proven early-stage VC partnerships, emphasizing speed, service, and a low-friction approach for founders and co-investors.
Before joining DAG, Williams spent more than a decade in venture capital. He worked at Summerhill Ventures (formerly BCE Capital) and at Teachers' Private Capital, the direct-investing arm of the Ontario Teachers' Pension Plan, where he concentrated on early- and mid-stage technology investments. This background spanning both Canadian institutional capital and Silicon Valley growth investing informs his focus today.
At DAG, Williams concentrates on enterprise infrastructure, SaaS, consumer internet, and clean tech — areas that map onto DAG's broader portfolio across IT, internet, fintech, security, mobile, advertising technology, digital health, and energy. He holds a B.Sc. from McGill University.
Investment Thesis & Focus
- Invests primarily at mid-stage and growth — generally Series B through Series D — rather than seed/angel; DAG typically comes in once a company has demonstrated traction and is scaling.
- Core personal focus areas: enterprise infrastructure, SaaS, consumer internet, and clean tech.
- DAG's model is to lead or co-lead growth rounds in companies already backed by established early-stage VCs, leveraging its network of "select, proven early-stage VC partnerships" to source quality deal flow.
- The firm positions itself around service, speed, and reliability — "consistent, expeditious, and superior service" to founders, LPs, and VC partners — meaning founders can expect a relatively fast, low-drama growth-round process.
- Geographically oriented toward U.S. technology companies, with a strong Bay Area center of gravity.
