Three decades turning hard physics into shipped hardware.
David W. Sherrer II is a defense-technology operator and inventor with a chemistry and materials-science background. His career has followed one through-line: take a physics-grade idea — micromachining, MEMS, mm-wave, advanced materials — and build the company that puts it in customer hands.
Career arc
David founded Haleos in 2000 to commercialize MEMS-based fiber optic components and optoelectronic packaging. The company was acquired by Rohm and Haas Electronic Materials in 2002. He then led product development at Rohm and Haas — managing hermetic laser packages, a 6-inch wafer fab, and the mm-wave packaging platform that would eventually become Nuvotronics.
In 2008 he founded Nuvotronics around the PolyStrata 3D metal micromachining process — work originating from DARPA's 3D-MERFS and DMT programs. Over the next decade Nuvotronics grew into a multimillion-dollar mm-wave technology company with deep partnerships across the largest U.S. commercial and defense primes. Cubic Corporation acquired Nuvotronics in 2019.
Today David leads MacroVation LLC as President and CEO, with Helicon Defense LLC as a co-founded RF and antenna venture (with Anatoliy Boryssenko, also a Nuvotronics alumnus). Both operate under the NuvoNexus, LLC parent.

Track record
Build the thing nobody has built. Prove it works. Ship it.
The work that has held David's attention across four decades is the same in every chapter: take a physics-grade idea that should be possible on paper, find the materials and process science that make it real, and stand up the manufacturing that turns it into hardware a customer can actually buy.
The throughline across Haleos, Nuvotronics, and MacroVation is a preference for hard problems where chemistry and process engineering — not just system integration — decide whether the product exists at all.
