The pitch is straightforward enough: a new material that uses 99% less metal and energy to achieve the same structural performance. The procurement cycle is anything but. For a French startup called TETMET, the bet is that its robotic, AI-driven process for making metal lattice structures can move from a lab curiosity to an industrial toolchain, and that the aerospace and automotive giants sensitive to every gram of weight will be the ones to write the first seven-figure checks.
Founded in 2023 and headquartered in Puteaux, France, TETMET has built its first production facility in Hoofddorp, Netherlands [Invest in Holland, Apr 2024]. The company calls its core technology Adaptive Spatial Lattice Manufacturing (ASLM), a system that uses AI-controlled robotic arms to laser-weld thin metal wires into complex, lightweight 3D structures [Sifted]. The value proposition is a direct attack on material and energy intensity, claiming its lattices require "two orders of magnitude less material and energy" than conventional solid metal parts [Invest in Holland, Apr 2024].
The wedge of weight and watts
TETMET is not selling a widget. It is selling a manufacturing capability, wrapped in a software suite. The offering splits into two parts. First, a Lattice Design Suite provides CAD and finite element analysis (FEA) plug-ins, integrated with platforms like Autodesk Fusion, letting engineers design and optimize structures for their specific load and vibration requirements [Autodesk Fusion Blog]. Second, the ASLM industrial toolchain takes those digital designs and physically builds them using robotic laser welding [HAL].
The wedge is the combined promise of radical weight reduction and energy efficiency, both in the final part and in the production process itself. For industries like aviation and space, where mass directly translates into fuel costs and payload capacity, even a single-digit percentage reduction is worth millions. TETMET's technology, according to one report, "can cut structural mass while optimizing performance characteristics such as vibration and thermal behavior" [I amsterdam]. The company explicitly targets manufacturers in Automotive, Aviation, and Space, aiming to support them "from design through scalable production" [Invest in Holland, Apr 2024].
The team building the toolchain
Public leadership details are focused on operational roles rather than a classic founder narrative. Tom Vroemen is identified as the CEO, with an EMBA from HEC Paris [HEC Stories]. Peter Evers serves as the Chief Technology Officer, a key technical contact for the company [Prospeo]. The team appears to be engineering-heavy, with roles like Head of Process R&D (Pierre Lapouge) and a mechatronics team cited in relation to the first factory build-out [LinkedIn, Tom Vroemen]. The company is estimated to have between 11 and 20 employees [Prospeo].

Traction and the first factory
The most concrete signal of progress is the establishment of that first ASLM production facility in the Netherlands, announced in April 2024 [Invest in Holland, Apr 2024]. This move is framed as strengthening the Netherlands' position in advanced manufacturing and suggests TETMET is moving beyond R&D into pilot-scale production. The company has secured backing from ID4 Ventures, which led an undisclosed seed round [F6S, Crunchbase]. The absence of public customer names or deal sizes is typical for early-stage deeptech selling into large, slow-moving industrial sectors, where sales cycles are long and partnerships are often developed under non-disclosure agreements long before a public announcement.
Where the wheels could come off
The ambition is clear, but the path to commercial scale is lined with hurdles endemic to capital-intensive hardware startups. The risks are not about the physics, but the economics and the adoption curve.
- The capital intensity trap. Building and scaling robotic manufacturing cells is expensive. The undisclosed seed round from ID4 Ventures will need to be followed by significantly larger rounds to fund factory expansion, equipment, and a sales team capable of engaging with aerospace primes. The burn rate before achieving meaningful revenue will be high.
- The qualification cliff. Parts for airplanes and cars don't just need to be lighter; they need to be certified. The process of getting a novel material and manufacturing method approved for flight or safety-critical automotive applications is measured in years, not quarters. This timeline can strain venture-backed runway.
- The incumbent response. Large manufacturers have their own advanced R&D departments and existing supplier relationships. A company like AddUp, a joint venture between Michelin and Fives, offers metal additive manufacturing (3D printing) solutions and could develop competing lattice capabilities [Crunchbase]. The competition is not just other startups, but the internal advanced manufacturing groups at Airbus, Boeing, and major automotive OEMs.
TETMET's answer likely hinges on proving not just feasibility, but a compelling total cost of ownership argument that includes energy savings in production and performance gains in use. Its low-energy manufacturing claim is a direct counter to one critique of advanced materials: that they are too energy-intensive to produce [VoxelMatters, May 2024].
The next twelve months
The coming year will be about moving from a single demonstration facility to proven pilot production for a flagship customer. Key milestones to watch will be the announcement of a first major industrial partner, likely an automotive tier-one supplier or a space component maker, and a subsequent, larger funding round to scale the Hoofddorp operation. The company will need to demonstrate that its ASLM process can reliably produce parts that meet not only design specs but also the rigorous quality and testing standards of its target industries.
For now, the ideal customer profile is clear: a senior engineer or advanced manufacturing lead at a tier-one aerospace or automotive supplier, who is measured on reducing vehicle mass and is budget-owner for new production technologies. They are evaluating TETMET not as a science project, but as a capital expenditure that must pay back through lighter, cheaper-to-move final products. The realistic competitive set includes other advanced manufacturing startups, established metal 3D printing firms like AddUp, and the internal manufacturing innovation groups of the very companies TETMET hopes to supply. The bet is that a dedicated, robotic-first process for lattices can outmaneuver both the startups and the giants on speed, cost, and material efficiency. It's a high-stakes procurement cycle, but the weight savings, if real, justify the climb.
