Inside a cavernous 1930s-era warehouse on the northern edge of Brooklyn, the ancient and all-but-extinct art of stone carving is having a 21st century rebirth. This is the new headquarters of Monumental Labs, a quirky but audacious startup that is combining the meticulous chisel-and-hammer craft of stone carving with the prowess, speed, and efficiency of robotics and artificial intelligence.

Using an $8 million round of venture capital funding, the 2-year-old company is turning this aging warehouse into a modern stonecutting factory capable of quickly producing highly detailed decorative facades, museum-grade marble sculptures, and towering stone monuments. And if founder Micah Springut gets his way, the company will soon be trying its robotic arms at an even grander project: reinventing the way buildings get built.
