Why this company matters

AMPulse analysis, not a company disclosure

TETMET is an early-stage French hardware company developing Adaptive Spatial Lattice Manufacturing (ASLM), a process that combines AI-controlled robotics with precision laser welding to build large-scale lattice structures. Unlike conventional layer-based additive manufacturing, ASLM constructs open-architecture truss geometries directly, aiming to reduce material waste by up to 40% compared to traditional subtractive or formative methods.

The company's platform integrates robotic fiber laser beam steering with real-time AI path planning, enabling the fabrication of architectured materials at scales impractical for powder bed or directed energy deposition systems. TETMET has established its first ASLM production facility in Hoofddorp, Netherlands, and an operational lab in Paris La Défense. The process is designed for circular manufacturing and is being positioned for decentralized production and in-space servicing, assembly, and manufacturing (ISAM).

TETMET targets engineering, space exploration, and sustainable manufacturing verticals. Named partners include construction firm PERI and launch vehicle developer MaiaSpace. The company raised €5.7 million from investors including id4 Ventures, Wendel, MFG Invest, Material Ventures, rpv, Super Capital VC, Climate Club VC, and Sequoia Capital. CEO Jules Hammond previously co-founded audience engagement platform BuzzMaster and equity crowdfunding firm CrowdAboutNow.

The company's differentiation lies in its focus on large-scale lattice structures rather than dense components, and its emphasis on in-space assembly and material circularity. Key open questions include whether ASLM can achieve the dimensional accuracy and repeatability required for critical aerospace applications, and how its cost per part compares to incumbent metal additive and subtractive processes at production volumes.
