Our Portfolio

Zell Lurie Fellows take a hands-on approach to investing that leverages the talents and resources available at the Stephen M. Ross School of Business at the University of Michigan to make a real impact for the entrepreneur and the University. The fund has made several investments spanning healthcare, cleantech, technology, and consumer companies. Company descriptions were largely taken from company websites.

Accio Energy

Accio Energy’s EHD wind energy system generates electricity using wind and charged water mist. The wind separates positive and negative charges as it moves the charged water mist. The separation of charges creates high-voltage, direct current electricity. The generator itself has no moving parts and consists of wind-permeable flat panels composed primarily of mass-produced tubes. The panels can combine into arrays, easily scaling from kilowatts to gigawatts. Accio’s generator is modular, transportable, and cost effective.



The AdAdapted platform gives independent app publishers easy-to-use technology for serving customized native ads and a straightforward digital marketplace that connects their apps with advertisers. At the same time AdAdapted provides a simple and efficient interface for those advertisers to find the right audience, and to streamline their efforts across multiple mid-tier apps. By solving the pain points of both the publishers and advertisers, AdAdapted also enhances the user experience by replacing disruptive banner ads.



AlertWatch, Inc. is an Ann Arbor-based spinoff from the University of Michigan Health System, and produces clinical decision support systems for hospitals. Founded in 2011, AlertWatch simplifies patient monitoring with intuitive products for the OR or ICU.

AlertWatch products now run at the University of Michigan and several other training hospitals across the United States.


Ambiq Micro

Ambiq Micro was founded in 2010 on the notion that extremely low power semiconductors are the key to the future of electronics.

Ambiq Micro developed a patented Subthreshold Power Optimized Technology (SPOT™) platform that dramatically reduces the amount of power consumed by semiconductors. By applying SPOT, Ambiq produces the world’s lowest power real-time clock (RTC) and microcontroller (MCU), Apollo.

Through the use of its pioneering ultra-low power technology, Ambiq is helping innovative companies around the world to develop differentiated solutions that reduce or eliminate the need for batteries, lower overall system power, and maximize industrial design flexibility.


Arbor Photonics / nLight

Arbor Photonics, a high-power fiber laser startup, was founded in Ann Arbor and originated in the U-M's Department of Electrical Engineering and Computer Science (EECS). In early 2013, Arbor Photonics was acquired by nLight, a semiconductor laser maker headquartered in Vancouver, Washington. The ZL Fund maintains a stake in nLight.


Are You a Human

Are You a Human is the curator of The Verified Human Whitelist™, which allows anyone using it to be certain they are addressing a verified human before they serve content, services, or ads.



ContentOro delivers high-quality content by working with publishers to extract the contents of fresh and relevant books and stream them to customers’ websites with proprietary software.


Fusion Coolant

Developed by researcher, educator and serial entrepreneur, Dr. Steven Skerlos, Fusion's critical patents secure the process of using supercritical carbon dioxide as a machining coolant and vehicle to deliver dry and enhanced lubrication to a cutting zone for applications demanding high lubrication and high cooling. Cooling and lubrication are achieved via single channel delivery because supercritical carbon dioxide completely dissolves lubricants. This allows for unprecedented heat removal potential and lubricity.



PHASIQ’s proprietary Micropatterned Phase-Separation Technology™ enables scientists to measure protein levels in a multiplex, cost-effective and cross-reaction free manner, thereby accelerating protein diagnostics and therapeutics development.



Reveal is an early-stage technology spin-out from the University of Michigan based in Ann Arbor, MI. Reveal designs and sells automated software solutions for performing scalable and comprehensive verification of digital logic designs to chip design firms.
