Matter Venture Partners Closes $450M Fund II

Matter Venture Partners has closed Matter Venture Partners Fund II, L.P. at $450M, giving the Silicon Valley firm a larger vehicle for early-stage HardTech investments across semiconductors, robotics and Physical AI, AI infrastructure, quantum computing, advanced manufacturing, energy building blocks, and AI for physical sciences. The final close was announced on September 16, 2026, and follows Matter's $300M inaugural fund from 2024.

The capital accounting is unusually clear. An amended SEC Form D reports $450M offered and sold, $0 remaining, 151 investors, and a first sale on December 23, 2025. Matter's original filing listed a $350M offering, which means the final close exceeded that starting amount by $100M.

The larger story is what the fund is designed to carry. HardTech companies can prove a technical result and still fail in the long passage through manufacturing, suppliers, qualification, customer adoption, and global deployment. Matter is building its fund around those handoffs, combining venture capital with a strategic limited-partner network positioned inside the industries its portfolio companies need to enter.

What Matter Venture Partners Closed

Matter Venture Partners announced the $450M final close through an official release. The vehicle is Matter Venture Partners Fund II, L.P., a Delaware limited partnership classified in its SEC filing as a venture capital fund. The filing identifies Wen Hsieh as managing member of the general partner.

Fund II follows a $300M inaugural vehicle announced in March 2024. At the time, Matter was a young firm built by investors and operators with long histories in semiconductors, robotics, and other technically demanding markets. Two and a half years later, the second vehicle is 50% larger than the first and fully subscribed above its original $350M filing amount.

The firm says the new fund will continue backing early-stage companies. Matter has not publicly disclosed a check-size range, ownership target, reserve strategy, fees, or return profile, so those details should remain outside any confident assessment of the vehicle.

A HardTech Fund With an Operating Thesis

Matter was founded in 2023 by Wen Hsieh, Founding Managing Partner; Haomiao Huang, Founding Partner; and Mel Tang, Founding Operating Partner and CFO. Hsieh spent 17 years at Kleiner Perkins and led HardTech investing there, while Huang brought experience as an engineer, repeat founder, and investor. Tang previously held operating and finance leadership roles at technology companies including Ring and Demand Media, according to Matter's announcement.

That mix matters because HardTech companies rarely move in a clean line from research to revenue. A semiconductor startup may need fabrication, packaging, testing, systems integration, and customer qualification before meaningful scale appears. A robotics company has to make software perform inside machines that encounter messy physical environments. An AI-infrastructure company can be limited by networking, power, equipment availability, or financing long before demand disappears.

Matter's response is to treat operating access as part of the investment model. The firm says it supports founders across manufacturing scale-up, supply-chain development, technology partnerships, talent, and customer relationships in the United States, Taiwan, Japan, Europe, Singapore, the Middle East, South Korea, and Mexico.

Why Matter's Strategic LP Network Matters

The Fund II announcement names ASML, Development Bank of Japan, Kleiner Perkins, Nitto Denko, Quanta Computer, Resonac, Sojitz, and TSMC among Matter's strategic limited partners. Nitto separately disclosed a $10M investment, describing access to semiconductor and Physical AI ecosystems as part of its rationale.

Those organizations span semiconductor equipment, advanced materials, electronics manufacturing, industrial commercialization, and institutional capital. Matter says strategic LPs can work with portfolio companies as technology collaborators, early customers, co-investors, manufacturing partners, suppliers, and entry points into industry networks. That is an operating ambition, not a guarantee that every LP will participate in every company, but it shows what Matter expects the network to do.

For founders, the distinction is practical. Capital pays engineers and buys time. A credible manufacturing introduction, qualification partner, early customer, or supplier relationship can determine whether that time produces a business.

The Portfolio Shows the Mandate in Motion

Matter's portfolio already spans chips, AI networking, robotics, advanced manufacturing, and compute infrastructure. The Fund II release highlights companies including Q.ai, Rhoda AI, Eridu, Path Robotics, Volta, ChipAgents, and Ambiq.

These companies operate at different points in the physical technology stack. Eridu is developing networking technology for AI infrastructure, Path Robotics builds AI-powered welding systems, ChipAgents applies agentic AI to semiconductor design, and Ambiq develops ultra-low-power processors. The examples do not establish Fund II returns, but they make the firm's stated category boundaries easier to see.

What the $450M Close Signals

Matter's close arrives while AI demand is pulling more investment toward the physical systems behind compute. Faster models still depend on chips, networking, data-center equipment, power, materials, manufacturing capacity, and machines that can operate in the real world. The category is receiving more attention precisely because software ambition has started running into physical constraints.

Fund II gives Matter more capital to select companies inside that shift, but the fund's real test will occur far from the closing announcement. Its relevance will be shaped by whether the firm can help technical founders make the difficult transitions between invention, production, qualification, and commercial scale.

The $450M is now committed. Matter's strategic network will have to turn that commitment into useful operating access as the next generation of HardTech companies moves from promising systems to products that industries can actually build and buy.
