Job Description
Opto is engineering the future of private markets to improve client outcomes and drive capital to the most transformative ideas.
The opportunity is huge. The global alternative investments industry is forecast to grow to $30T by 2029, however the private investment process typically remains opaque, highly manual, and error-prone, which limits access to the select few insiders who are willing to bear the pain.
Opto is a revolutionary end-to-end solution for wealth managers of any size- from small investment advisors to large multi-family offices to private banks- to build, fundraise for, and manage private markets programs at scale. We combine exceptional Silicon Valley engineering talent with experienced investors and industry specialists to fix this broken system through the power of technology. Our platform banishes the nightmare of slide decks, spreadsheets, and paperwork to the past, and arms our clients with the tools, data, and guidance to identify and access the right opportunities for their clients.
Fixing private markets will not be easy and demands courage, but we’re not afraid to do things differently. We are unapologetically bold. We value strong opinions, clear communication, and purposeful execution.
Up for the challenge? Come join us.
