D4 is an early-stage investment firm backing bold founders building the future. We invest in transformative technologies-particularly across AI, robotics, and frontier sectors-with the potential for lasting global impact.

Our founding partners have built billion-dollar tech companies through both booms and downturns. That experience shapes our conviction: we back real traction, working products, and capital-efficient teams from Pre-Seed to Series A.

We also pursue opportunistic plays in distressed or overlooked assets with potential for reinvention and long-term value.

At D4, we’re long-term partners to builders-investing in innovation that endures.
