Tech-equipped teams who get you

Executives-in-Residence who support you
High-potential portfolio companies, meet proven operators, independent board members, and advisors positioned to unlock your growth. Companies like yours choose our XIR program for its unmatched guidance and institutional value-adds.
We take a data-driven approach to creating the right matches, developing a specific thesis in collaboration with the XIR, and using Beacon—along with our network—to search for the right founder and partner companies. After that, there's nothing left to do but grow.
