Madrona Venture Group

Madrona Venture Group

Madrona Venture Group invests in seed and early-stage technology companies in areas including cybersecurity.

We are a resource-rich venture firm that offers a well-established network of internal and external expertise for every stage of the company-building process. Our deep connections give our portfolio companies a competitive advantage in financing, recruiting, strategic planning, and partnering.

We are proud and humbled to work with some of the brightest and most tenacious founders around. Sound like you? It’s never too early to talk to us about your idea, technology or vision. A seed investment for us can be small, sometimes even just a few hundred thousand dollars at the earliest stage, meaning a founder and an idea. Even if we aren’t the right fit, we may be able to introduce you to someone who is.
