Galux, a South Korean biotech at the forefront of AI-driven protein design, has successfully secured $29 million in a Series B financing round. This new capital brings the company's total funding to $47 million, reinforcing its position in the competitive biopharmaceutical landscape. The funds are earmarked to advance its proprietary GaluxDesign platform, which specializes in creating novel antibody therapeutics through artificial intelligence.
Investor Confidence and Strategic Growth
The financing round saw robust participation from both existing and new institutional investors, signaling strong market confidence in Galux's vision. Long-term supporters like InterVest, DAYLI Partners, and PATHWAY Investment were joined by new backers including Yuanta Investment and Korea Development Bank. This diverse syndicate underscores the broad appeal of the company's technology and its potential to generate significant returns.
Sang-gyun Kim of InterVest praised Galux for its consistent technical depth and disciplined execution since its initial seed investment. This latest funding builds upon an $18 million Series A round in 2022 that enabled crucial advancements in its AI platform. The successful Series B closure reinforces the company's sustained growth momentum and its ability to deliver on key milestones.
A Proven Platform Driving Innovation
At the core of Galux's success is its AI-powered platform, GaluxDesign, which excels in the technically demanding field of de novo antibody design. The platform has demonstrated impressive, metric-backed results, achieving a 31.5% overall hit rate in generating AI-designed antibodies. This high success rate significantly accelerates the initial stages of drug discovery compared to traditional methods.
The platform's capabilities have produced tangible drug candidates, including a high-affinity antibody for the cancer target PD-L1 with strong developability. Furthermore, GaluxDesign has proven its precision, with its AI-designed structures showing high consistency with experimental cryo-EM results. This validation is critical for designing effective and reliable protein-based drugs for complex diseases.
Redefining Drug Discovery and Partnerships
Galux's approach signifies a broader paradigm shift in the pharmaceutical industry, moving from probabilistic screening to rational, AI-driven drug design. This evolution allows for the creation of highly specific molecules tailored to complex biological targets. The company's technology can even design antibodies for targets without experimentally resolved structures, opening new avenues for treatment.
The company has effectively leveraged a collaborative business model, establishing strategic partnerships with firms like Celltrion, LG Chem, and Boehringer Ingelheim. In these arrangements, Galux focuses on AI-driven antibody engineering and early validation, while its partners manage later-stage development. This model streamlines the R&D process and enables the development of complex treatments like multi-specific antibodies.
Future Ambitions and Platform Expansion
With the new proceeds, Galux plans to enhance its AI platform, expanding its capabilities beyond simple binder design to include functional activity and developability. CEO Cha-ok Seok stated this will enable the creation of more robust and therapeutically viable molecules. The investment will also fuel R&D infrastructure expansion and accelerate the preclinical validation of its proprietary pipelines.
A key focus is extending its platform to address historically challenging target classes that have been difficult to drug using conventional methods. This includes complex proteins such as G-protein-coupled receptors (GPCRs) and ion channels. By tackling these targets, Galux aims to unlock entirely new therapeutic opportunities for patients worldwide.
The successful $29 million Series B funding round marks a pivotal moment for Galux, providing the resources to scale its innovative AI platform. This investment is not merely a financial achievement but a strong endorsement of its rational drug design approach. As Galux advances its technology and pipeline, it is well-positioned to deliver next-generation protein therapeutics for previously intractable diseases.
