We're entrepreneurs, engineers, scientists, developers, and creators.

Our mission is to be a catalyst for innovation

by enabling creators to rapidly prototype and efficiently manufacture precision machined parts.

What We Do

We will provide the fastest and most cost-effective way for anyone to create high-precision, production-grade CNC parts.



Starting with a digital design of a part, our software automatically decides how to efficiently machine that part on a CNC mill.



By making it easier, faster, and less expensive to go from “art to part” we will accelerate product development, encourage innovation, and support the creation of the next generation of products that improve our world.



Our Team

Andy Powell

Chief Executive Officer

Andy Powell is a lifelong entrepreneur and problem solver. Prior to launching Toolpath Labs, Andy was the co-founder and CEO of CallRail, a software company providing marketing analytics to more than 180,000 small businesses.



Under Andy’s leadership, CallRail grew to employ more than 275 people with more than $75M in annual revenue and $10M in annual profitability. CallRail was named to the Inc. 5000 list of fastest-growing companies for six years consecutively, and recognized as a Best Workplace by Inc. Magazine.



Andy grew up in Columbus, Georgia and graduated from Georgia Institute of Technology (2005) with a B.S. in Industrial and Systems Engineering. He lives south of Atlanta, in Peachtree City, with his wife Allison and three daughters.

Justin Gray, Ph.D.

Chief Technology Officer

Justin Gray is an optimization expert with degrees in both computer science and aerospace engineering and 17 years of experience with software development and engineering design.



He is one of the lead developers on the open-source OpenMDAO optimization framework, and has applied it to develop jet engine design models, aircraft design models, and complex multiphysics optimizations.



He received a B.S. degree in Aerospace Engineering from the Georgia Institute of Technology (2006), his M.S. in Computer Science (2012) from Case Western Reserve University, and his Ph.D. (2018) in Aerospace Engineering from the University of Michigan. Justin is an avid cyclist with a passion for all things mechanical. He lives in the Cleveland area with his wife and son.

Fei Shen

Software Engineer

Fei Shen is a Ph.D. candidate majoring in mechanical engineering at the University of North Carolina at Charlotte. His research focuses on automated tool path planning, reverse engineering, and precision metrology.

Prior to joining Toolpath Labs, he worked as an intern at the Corporate Technology department of Siemens AG for three years. He was one of the lead developers on two reverse engineering tools (Mesh from Cloud and Combine Facet Bodies) of Siemens NX software.

He received a B.S. degree in measuring and testing technology & instruments from Hefei University of Technology (2012), and his M.S. degree in instrument science and technology (2015) from National Institute of Metrology of China. He lives in the Charlotte area with his wife Tong.



Joshua Tarbutton, Ph.D.

Technical Advisor

Joshua Tarbutton is an associate professor of mechanical engineering at UNC Charlotte and a licensed professional engineer in machine design. His research examines how innovative geometrical and process solutions can solve bottlenecks that exist between design and manufacturing. His primary focus is on how tool path generation can be automated to increase manufacturing productivity.



He is the co-founder of Bravo Team, a small team of engineering mavericks that support organizations with engineering capacity and small batch production and prototyping in their machine/fab shop.



He received a B.S. degree in mechanical engineering from the Georgia Institute of Technology (2005), and his M.S. (2007) and Ph.D. (2011) degrees in mechanical engineering from Clemson University. He was a professor at USC from 2012-2016 when he moved to UNCC. He is an Army Veteran and lives outside Charlotte with his wife and four children.
