Eric Slaim

Eric Slaim is the founder, chief architect and CEO of Eleven. He brings over 20 years experience in alternative investments and hands-on design, development, marketing and branding expertise to building transformational solutions.

Eleven was born from Eric's firsthand experience inside the hedge fund industry. After years both investing in hedge funds and advising at an institutional level, Eric left his roles to bring people and firms throughout the industry better access to tools, information and each other.

He picked up a few programming languages along the way (about 11) and built and grew HFIN One, which became a $1 trillion platform for the hedge fund industry with users in 35 countries and gave rise to Eleven today.

He also founded HFIN Creative, a branding, creative and digital agency to help customers increase success and scale growth further.
