  • Stathera

    Participated · Series B · Jun 2026

    Stathera develops MEMS-based silicon timing products built on its proprietary DualMode® architecture, aiming to replace legacy quartz timing in a range of electronics from smartphones and wearables to AI data centers. Its GEN2 32.768 kHz product line is moving into mass production and broader GEN2 portfolio products are sampling with Tier 1 OEMs. Stathera's silicon oscillators are manufactured in standard semiconductor fabs and are positioned to offer smaller footprint, higher reliability, improved shock and vibration resilience, and no external load capacitors compared with quartz. The company is launching a GEN3 program purpose-built for the performance and reliability demands of AI-CED applications and is targeting first customer samples in 2028. Stathera positions the AI data center timing opportunity as a fast-growing segment within an estimated US$11 billion annual timing market and cites an industry estimate that AI data center time-synchronization could represent a cumulative US$1.5 billion opportunity by 2030. The company is headquartered in Montreal and has raised US$75 million in total funding following the Series B.

  • Normal Computing

    Participated · Equity · Mar 2026

    Normal Computing develops Normal EDA, an AI platform that applies frontier techniques (including auto-formalization combining LLMs with formal logic) to accelerate semiconductor design and automate DV/RTL workflows. In parallel it advances the Carnot hardware program to produce physics-based ASICs aimed at dramatically improving energy efficiency; the company completed tape-out of CN101 in August 2025. Normal says it partners with more than half of the top ten semiconductor companies by revenue and has earned trust to drive production silicon. The company has raised over $85 million to date, including a $50 million strategic round led by Samsung Catalyst Fund in March 2026. Normal was founded in 2022 and is headquartered in New York, with offices in San Francisco, London, and Copenhagen, and receives programmatic support from ARIA for some of its work.

  • PowerLattice

    Led · Series A · Nov 2025

    Founded in 2023 by veteran engineers from Qualcomm, NUVIA and Intel, PowerLattice is tackling the data-center energy crunch with a miniature power-delivery chiplet that positions power circuitry directly beside the processor to minimize energy loss. Pat Gelsinger hails the team as a "dream team of power delivery," citing internal tests that show over 50% power savings versus conventional approaches. The first production run is already underway at TSMC, where an unnamed manufacturing partner is evaluating the technology. Looking ahead, the startup plans to open its chiplet for broader trials in the first half of 2026 with prospective customers such as Nvidia, Broadcom, AMD, Cerberus, Grok, d-Matrix and NextSilicon. By enabling more energy-efficient AI and cloud chips, PowerLattice aims to capture meaningful share in a market hungry for power savings. The company has raised $31 million to date, including a newly announced $25 million Series A, and investors expect it will pursue a larger round to finance full-scale production.

  • Movandi

    Participated · Equity · Oct 2025

    Movandi is a connectivity‐focused semiconductor and systems company whose portfolio spans RF chipsets, beamforming silicon, phased-array antennas, and software-defined networking. Its technology underpins high-throughput, low-power, and intelligently steered wireless links for 5G networks, fixed wireless access, and non-terrestrial (LEO satellite) communications. With more than 115 issued patents, the firm has already deployed mmWave solutions that improve the economics and performance of commercial 5G roll-outs. The company now aims to translate this edge into satellite broadband and hybrid fixed-wireless deployments, addressing range, cost and latency constraints faced by operators. Future plans include opening an Oman office to tap regional talent and co-develop solutions aligned with Oman’s Vision 2040 initiative. Headquartered in Irvine, California, Movandi positions itself as a bridge between Silicon Valley innovation and Middle-East market expansion. The latest capital injection strengthens its ability to scale production, broaden its product roadmap, and pursue global market entry opportunities.

  • HiOctave

    Participated · Equity · Oct 2025

    HiOctave is an AI software company that equips SMBs with enterprise-grade, off-the-shelf customer-satisfaction tools such as autonomous voice and digital agents, automated quality monitoring, voice-of-customer analytics, and escalation management. Built to be mobile-first and easy to deploy, the system lets lean teams deliver high-touch, high-trust support without extensive vendor selection or large overhead. The company was incubated by Crescendo co-founders Andy Lee and Anand Chandrasekaran, and is now led by co-founder and CEO Golan Agmon, formerly eCommerce COO at Wix. HiOctave’s mission is to bring “agentic AI” benefits—higher conversions, increased revenue, and deeper customer relationships—to the more than 90% of U.S. businesses that fall into the SMB category. The recently secured $15 million in funding will accelerate product development and go-to-market efforts. While HiOctave is pre-revenue, its founding team’s prior venture, Crescendo, scaled to $100 million in revenue within 20 months, underscoring their operational expertise.
