Clients First
We've been entrusted with our clients' capital, making clients our first and foremost focus. From our investment focus to how we report results, our goal is to provide clients with clarity, transparency, responsiveness -and results.

One Firm, Many Markets
When you work with Northgate, you benefit from our global perspectives and diverse experiences-all of which make for a more robust operation. You also have the assurance that as a firm, we are united in the disciplined approach and investment philosophies we follow.

Obligation to Dissent
At Northgate, there is no hierarchy of ideas. From a proposed investment strategy or decision about pursuing a new market, it is your responsibility-your obligation-to express your opinion. And it's the entire team's obligation to listen and explore.

No Complacency
Good enough is never enough. We’re a team driven by superior results. Contentment is not in our DNA. We are passionate, driven and results-oriented. We value and know the importance of always seeking out new thinking.

Relationships Rule
From client interactions to the venture capital and private equity firms we invest in, forging lasting relationships is our mantra. We know successful relationships start with commitment and trust, and continue to grow with mutual respect and benefit.

Unparalleled Teamwork

Virtually every investment firm will attest that its people are its greatest asset.

At Northgate, each of our partners has an equal voice in our investment focus and approach. For most firms, that equanimity is rarely achieved. From the start, we’ve promoted a culture where smart, opportunistic thinking, thorough due diligence and sound perspectives are valued. We believe every team member is a factor in the firm’s success—and in the returns we deliver to our limited partners.

Working from our offices in Northern California, London, New Delhi, Hong Kong and Mexico City and Rep Offices in Tel Aviv and Melbourne, our teams bring more than 100 years of investment experience and relationships to every investment decision we make. Our team’s experience within private equity and venture capital includes tenure at Bain Capital, Horsley Bridge Partners, McKinsey & Co, McKinsey Investment Office (MIO), New Enterprise Associates and more.
