Your private investment team

What we believe

We exist to simplify advisors' lives and help improve their clients' ability to reach their goals.

Core Tenets


The private investment process is broken.


All investors deserve access to high-quality private investments.


Most investors are overexposed to public markets.


Aligned incentives are key to great partnerships.


Who we are


We provide more than just access - we build personalized private market portfolios and work with advisors to meet client goals over the long term.


We are expert builders who don’t accept the status quo. We have re-invented industries with technology and are obsessed with building a platform to bring private investing into the 21st century.


We are a team of seasoned investors, allocators, and operators committed to providing the best investment experience from returns to reporting, and everything in between.


We are Opto

World-class investors, allocators, operational specialists, and technologists who are passionate about creating a better way to access private markets.
