Monumental Labs develops advanced robotic systems powered by artificial intelligence to automate intricate stone carving. This enables large-scale production of architectural ornamentation and sculpture. Their technology integrates digital design with precision robotics, streamlining traditional masonry and making custom stone fabrication efficient, reintroducing complex stone work into modern construction.
The company was founded by CEO Micah Springut, with Sebastian Marino as CTO. Springut, having learned traditional stone carving, recognized the opportunity to merge ancient artistic practices with modern automation. The core insight was to leverage robotics and AI, overcoming labor-intensive and costly aspects of hand-carved stone, thereby democratizing access to custom architectural elements.
Monumental Labs primarily serves architects, designers, and developers integrating durable and aesthetically rich stone features. The company envisions stone becoming a cost-effective material, competitive against alternatives, fostering a widespread resurgence of sculpted buildings. Their long-term vision is to spark a renaissance in the built environment through scalable, robotically-enabled stone craftsmanship.

Monumental Labs is a portfolio company developing an AI-powered robotic fabrication platform for stone carving, enabling mass production of intricate sculptures and architectural elements at reduced costs.[1][2][5] It serves artists, collectors, architects, developers, and restorers by solving the high cost and time barriers of traditional hand carving—reducing fabrication expenses by up to 90% through robotic milling combined with hand finishing.[2][4][5] The company has shown strong growth momentum since starting operations in July 2023 with one robot, expanding to a team of over 19 members and planning a 40,000 sq. ft. workshop in New York City housing a dozen robots by spring 2025.[2][6]
Founded in 2022 by Micah Springut, a tech entrepreneur and marble-carving hobbyist, Monumental Labs emerged from Springut's vision to automate stone sculpture production, making it faster and cheaper than manual methods.[1][2] Sebastian Marino serves as CTO, leading the technical development.[2] Operations began in July 2023 with a single robot and stone carver in Mount Vernon, New York; early traction included high-profile projects like a Stripe statue, marking their first corporate customer.[1][2] The company quickly scaled, growing its team and securing seed VC funding while committing to revive American stone craftsmanship.[1][2][6]
Monumental Labs rides the wave of AI-robotics convergence in construction and manufacturing, automating labor-intensive crafts amid labor shortages and rising demand for sustainable, durable materials like stone—the world's greenest construction option.[2][5] Timing aligns with post-pandemic architecture trends favoring ornate, historical revival (e.g., Florence-style or Art Deco) over minimalist modernism, fueled by market forces like green building mandates and tech investments in humanoid/general-purpose robotics.[1][2][3] It influences the ecosystem by training new craftsmen, fostering patron communities, and competing with firms like Figure or Sunrise Robotics, potentially sparking a "stone renaissance" in urban development.[2][3][5]
Monumental Labs is poised to disrupt stone fabrication, with its spring 2025 NYC workshop launch enabling scaled production and broader adoption in art, restoration, and new builds.[2][6] Advancing AI for end-to-end automation—beyond current manual toolpath programming—will drive further efficiency, while trends in AI hardware (e.g., cheaper robots) and sustainable architecture amplify growth.[1][3][6] Its influence may evolve from niche sculptures to mainstream infrastructure, empowering architects to prioritize beauty and durability, ultimately reshaping cities with affordable, robot-crafted splendor.[2][5]
