Aether Biomachines, an American artificial intelligence company focused on delivering real-world industrial solutions using AI-designed proteins, today announced it has raised an additional $15 million in funding. The round was led by Tribe Capital, with significant participation from both new and existing investors, including Natural Capital, Henkel Corporation, Resilience Reserve, Shrug Capital, 4DX Ventures, Unless Partners, and Radicle Impact. This latest capital injection brings Aether’s total funding to $64 million.
Aether Biomachines is pioneering a fundamental shift away from outdated, capital-intensive chemical manufacturing processes. The company combines proprietary AI and high-throughput robotics to design proteins that function as molecular assemblers—tiny, nanoscale machines capable of constructing materials with atomic precision. This approach promises the sophistication of massive chemical factories at a fraction of the size, enabling faster, more affordable, and environmentally sustainable production.
The company’s technology is already demonstrating transformative results across critical sectors. Its AI-designed proteins have helped create new polymer additives, marketed as RapidPrint and Ultra 3D, that print up to 10 times faster and are twice as strong as current industry benchmarks. These “super materials” are vital for national security, aerospace, and defense applications, particularly in powering drones and complex parts.
Furthermore, Aether’s Protein Function Model has unlocked seven new classes of proteins targeting urgent environmental and industrial challenges, including:
Refining critical minerals like rare earth metals at lower cost.
Recycling plastics and capturing carbon.
Breaking down persistent “forever chemicals.”
Producing complex pharmaceuticals.
Pavle Jeremić, CEO and Founder of Aether Biomachines, emphasized the strategic importance of the funding. “Aether is building the foundation for the next industrial revolution. This funding will allow us to accelerate the discovery of proteins with transformative applications, including stronger, more scalable materials for defense and aerospace, and bring our first commercial products to more industries. Our latest funding positions us to turn breakthrough science into real-world solutions.”
The company plans to use the capital to expand its Protein Function Model, scale its first commercial materials products, and accelerate partnerships in manufacturing, sustainability, and national security.
Arjun Sethi, Chairman at Tribe Capital, underscored the market readiness of Aether’s approach. “We’ve seen many AI companies focus on discovery, but no one has taken the leap from designing proteins to delivering physical, market-ready products until Aether,” said Mr. Sethi. “Aether is proving that its approach isn’t just innovative in theory; it’s faster, more cost-effective, and higher-performing than traditional methods, setting the standard for what AI-driven chemistry can achieve in the real world.”
Editorial Opinion: Redefining Manufacturing and Geopolitical Resilience
Aether Biomachines’s success in securing $64 million underscores a profound, often overlooked, aspect of the modern industrial economy: the need for a non-linear leap in manufacturing technology. By treating proteins as programmable, nanoscale tools, Aether is moving beyond the incremental efficiency gains of the past few decades and establishing a platform that fundamentally changes how matter is manipulated. This is not simply a biological advancement; it is a foundational technology for reindustrializing the nation by creating inherently more efficient, less wasteful, and more cost-effective supply chains.
The true impact of Aether’s work lies in its dual application across both national security and environmental sustainability. Their ability to produce superior performance materials, like the 10X faster, 2X stronger 3D printing additives, provides a crucial domestic advantage in defense and aerospace manufacturing, reducing reliance on volatile global supply chains for critical components. Concurrently, the breakthrough in developing new protein classes for capturing carbon, recycling plastics, and breaking down hazardous “forever chemicals” positions Aether as an indispensable partner in the global transition to a circular economy. The company’s unique, proprietary dataset—built in-house through advanced high-throughput screening—is the bedrock of its Protein Function Model, a strategic moat that promises continued, high-impact breakthroughs. Aether is not just developing products; it is building the molecular toolkit that will power America’s next generation of resilient, high-performance, and sustainable industries.
