- CarbonSix
Participated · Series A · Jul 2026
CarbonSix develops deployment-ready robotic intelligence software and hardware, including robotic hands and manipulators, for manufacturing applications. The company emphasizes field reliability and immediate integration into production lines, and reports commercial contracts and scaling revenue as evidence of market traction. Its core business model is a proprietary "data flywheel" where tool usage in factories generates task-specific data that improves its AI models over time. The founding team includes executives and researchers with prior exits and advanced academic credentials, supporting technical and commercial credibility. CarbonSix plans to use its Series A proceeds to hire talent, scale infrastructure, and expand into global markets.
- Hyperlight
Participated · Series C · Jun 2026
HyperLight develops high-performance integrated photonics based on thin-film lithium niobate (TFLN), commercialized as its TFLN Chiplet™ Platform. The platform targets a range of optical interconnect applications including data center pluggables, coherent datacom and telecom modules, and co-packaged optics, and offers products supporting 200G-per-lane operation with 400G-per-lane solutions now sampling. The company emphasizes ultra-high modulation bandwidth, CMOS-level drive voltage, and ultra-low optical loss to reduce power consumption at higher lane speeds. HyperLight has established a strategic manufacturing partnership with UMC and Wavetek for high-volume foundry production on both 6-inch and 8-inch wafers. With the $80 million Series C, the company plans to expand manufacturing capacity, accelerate customer qualification, scale its platform, and deepen partnerships across foundry, semiconductor, networking, and systems integration domains.
- Nervonik
Participated · Series B · Apr 2026
Nervonik is developing a next-generation peripheral nerve stimulation platform that combines electrical stimulation with advanced sensing to enable more precise, personalized neuromodulation therapies. Its implantable leads have demonstrated the ability to record evoked compound action potentials (ECAPs) and other physiological biomarkers. The company is advancing clinical programs and preparing for commercialization of its PNS system. Recent financing will fund further development of its proprietary sensing capabilities and support commercialization activities. Nervonik is headquartered in Los Angeles, California.
- Aether Fuels
Participated · Convertible Note · Jan 2026
Aether Fuels is a clean-energy company commercializing Aether Auror™, a process that transforms industrial waste gas and biomethane into CORSIA-certified sustainable aviation fuel with more than 70 % greenhouse-gas reductions. Its flagship initiative, Project Beacon, is a 50 barrels-per-day (2,000 t per year) SAF plant being co-developed with Aster at the latter’s Bukom Island refinery in Singapore; engineering is underway, construction is slated for 2026, and commercial operations are targeted for 2028. The company is also planning to open a Singapore R&D center in 2026 to support ongoing technology scale-up. To bolster execution, Aether has added Stu Stott as Global Vice President of Projects and expanded its regional business development team. Including the latest round, Aether has raised more than US$60 million to date, funding pilot activities in the U.S. and the move from demonstration to commercial deployment. The new capital will accelerate Project Beacon and further maturation of its core technology.
- Lucidean
Participated · Seed · Dec 2025
Lucidean builds CohZero™, a coherent-lite optical interconnect architecture that offers coherent-class reach and bandwidth while operating within the cost and power envelopes of traditional intensity-modulation direct-detection (IMDD) systems. The platform is designed to slot into existing IMDD ecosystems—leveraging widely available lasers, simplified DSPs, and standard pluggable module architectures—so hyperscale data centers can scale to multi-terabit performance without a disruptive physical-layer overhaul. Lucidean is currently engineering 3.2 Tbps and 6.4 Tbps transceivers aimed at AI-driven fabrics and data-center interconnects. Following an $18 million Seed round, the company plans to expand R&D, validate CohZero™ performance, and accelerate productization. The capital will also support hiring as the team moves hardware toward commercial readiness. Industry veteran Dr. James Raring has joined as CEO, bringing more than 300 patents and deep experience in photonics commercialization. The company’s financial resources now position it to demonstrate its value proposition and pursue market entry, though no revenue or deployment metrics were disclosed.
