We are a new growth equity firm built on the premise that investors should do more than just provide capital.  That's why we founded Sunstone Partners. 

We have over 60 years of collective investment experience working with technology companies.  

We are excited to meet you and to build something great together.  

Let's Build Something Great

We’re changing the way investors work with growth stage companies.

We’re changing the way investors work with growth stage companies.

Our operational approach to investing creates real value in the businesses we partner with. Here are some ways we can help:

Sell More

We bring go-to-market best practices to help you grow revenues, reduce customer acquisition costs, and improve retention and upsell performance.

We also help you determine which direction to expand your technologies and products, and help identify complementary acquisitions in your space.

Hire Better

Recruiting top talent is hard and expensive. We leverage our extensive network to help companies fill key roles ranging from developers to c-level executives.

We also make available to you the Sunstone Operating Team, a group of successful founders and CEOs who can serve as trusted advisors to you.

Provide Liquidity

We realize most companies we work with don't need cash to fund day-to-day operations. That's why our capital is flexible.

We have the ability to provide partial liquidity to you and other founders, or purchase shares from earlier investors to clean up your cap table.

Maximize Value

We will help you put in place the pieces needed to sell your business at a premium in the market.

We have a strong history of transacting with both strategic and financial buyers, and understand what they seek. Let’s work together to create the best outcome for you and your company.

 

Sector Expertise

We focus on key verticals and sectors benefiting from macro tailwinds and technology disruption, and in which we have had numerous historical successful investments.  We take the time to understand growth trends and opportunities beyond the horizon, and seek to identify future industry leaders.  We invest in the following:

 
Are We Right For You?

Are We Right For You?

If the following describes your business, let’s work together.

$10 Million or Greater of Revenues

+20% Year-over-Year Growth

Profitable and a Capital Efficient History

 

Meet The Sunstone Team

The founding team has over 60 years of successful investing experience, most of which have been together at their prior firm, Trident Capital.
