PseudolithIC raises $6M for heterogeneous chiplet tech

PseudolithIC Inc, a Californian developer of chipsets, has raised $6 million in seed funding, led by Entrada Ventures, with additional investments from Foothill Ventures and Uncork Capital.
The investment will enable the company to speed the development and commercialisation of products which integrate compound semiconductor chiplets into silicon wafers.
The PseudolithIC technology is claimed to offer the high performance of a monolithic microwave IC (MMIC), but at a fraction of the cost. The company’s proprietary approach of integrating compound semiconductor chiplets with low-cost 300mm silicon wafers, is said to offer a blend of performance, power efficiency, and scalability.
The approach addresses key challenges in wireless communications, particularly for fast-growing and critical industries such as terrestrial and satellite communications, aerospace, and IoT (Internet of Things) applications, according to PseudolithIC.
“Our team is excited to push the boundaries of what is possible in RF technology,” said Jim Buckwalter, CTO of PseudolithIC and professor of Electrical and Computer Engineering at UC Santa Barbara. “The hybrid approach of combining silicon and compound semiconductor chiplets unlocks new potential for RF systems, enabling faster data rates, lower latencies, and better reliability. We believe our innovations will be game-changing for customers requiring high-performance wireless solutions.”
PseudolithIC is based in Santa Barbara, CA, and currently has a team of more than 15 employees. The fresh infusion of capital enables the company to expand its team and accelerate research and development to bring its products to market.
"We're really enthusiastic about leading PseudolithIC’s seed round,” said Alex Fang, managing partner at Entrada Ventures. “The wireless industry has been limited by the opposing metrics of performance and scale. We think Florian and Jim have developed something here that will unlock a new era in wireless systems that will result in unprecedented performance on mobile and satellite platforms."
Florian Herrault, CEO of PseudolithIC, said: “We are thrilled to have the backing of such investors as Entrada Ventures, Foothill Ventures, and Uncork Capital. Our goal is to lead the charge in providing cost-effective, high-performance silicon RFIC solutions augmented with compound semiconductors, that meet the ever-growing demands of next-generation wireless systems.”
