Founder voices

What it sounds like to work with us.

“Vex was the first cheque on Vortex AI. Three years later they're still in every quarterly board meeting and every hiring loop that matters.”
V
Avery Brooks
Founder & CEO · Vortex AI
“Their diligence process was the most rigorous and the most respectful we'd seen. We got more out of those three sessions than ten investor meetings.”
N
Tomás Reyes
Co-founder · Northrun
“When our pivot was unpopular, Vex backed it before any data agreed with us. That trust is the difference between a fund and a partner.”
H
Hadley Mason
Founder · Halcyn
“Vex's GTM intros sourced our first three enterprise customers and our first VP of Sales. The financial capital is the smallest part of what they bring.”

CEO · Cirrus Health
