Founding Story

Samuel P. Geisberg, a mathematician who emigrated from the Soviet Union and later worked on CAD at Computervision, founded the company in 1985 around the idea of parametric, feature-based solid modeling: dimensions and relationships drive the geometry, so changing one value updates the whole model. With backing arranged by attorney Noel Pasternak and engineering leadership from Mike Payne, PTC shipped Pro/ENGINEER in 1988 and went public in 1989.

Samuel P. Geisberg

Co-founder 1985

Background

Mathematician who emigrated from the Soviet Union in the 1970s and worked on CAD software at Applicon and Computervision before founding PTC.

Role at PTC Inc.

Samuel P. Geisberg founded Parametric Technology Corporation in 1985 after concluding that existing CAD systems could not easily update designs when requirements changed. His parametric, feature-based approach, delivered as Pro/ENGINEER in 1988, let a single dimension change ripple through a part, its assembly and drawings. Pro/ENGINEER helped PTC win large accounts such as Caterpillar in the early 1990s, and the same modeling approach was later adopted across the CAD industry, including by SOLIDWORKS and Autodesk Inventor.

Mike Payne

Co-founder 1985

Background

Mike Payne spent years at Prime Computer as director of CAD/CAM research and development before joining PTC in March 1986 as vice president of development. His technical leadership was instrumental in bringing Pro/ENGINEER from prototype to commercial product, and he built the engineering organization that delivered the parametric modeling engine. Payne's defining contribution was translating Geisberg's mathematical concepts into production-quality software that could run reliably on multiple UNIX workstation platforms simultaneously, a technical achievement that differentiated PTC from competitors who developed on single platforms and then ported.

Role at PTC Inc.

Mike Payne was a seasoned CAD/CAM software executive who joined PTC in March 1986, one month after being recruited by Samuel Geisberg, and immediately became vice president of development. At Prime Computer, Payne had directed CAD/CAM R&D and understood the technical limitations of existing 2D drafting and early 3D surface modeling systems. He recognized that Geisberg's parametric, feature-based approach could overcome these limitations if implemented with sufficient engineering rigor. Payne built the development team that transformed Geisberg's prototype into Pro/ENGINEER, the first commercially viable parametric solid modeling system. His decision to develop simultaneously on Sun, DEC, Apollo, SGI, and NEC workstations, rather than porting from a primary platform, gave PTC broader hardware compatibility than any competitor and accelerated customer adoption. Payne's engineering leadership during PTC's formative years (1986-1990) established the technical culture of rapid iteration and platform neutrality that persists in the company today. After leaving PTC, Payne continued his career in industrial software and remains a respected figure in the CAD industry. (Exact birth year remains publicly undisclosed).

Neil Barua

President and CEO

2024 – Present

Barua joined PTC through the $1.46B ServiceMax acquisition in January 2023, where he had been CEO, and became PTC's CEO in February 2024. Under him PTC reported FY2025 revenue of $2.739B and net income of $734M, then sold Kepware and ThingWorx to TPG in March 2026 to concentrate on the Intelligent Product Lifecycle across CAD, PLM, ALM and SLM. He has also emphasized AI built on customers' product data.

Jennifer DiRico

EVP and Chief Financial Officer

2024 – Present

As CFO, she heavily optimizes the company's operating margins as it transitions its massive, legacy on-premise industrial client base entirely to SaaS subscriptions.

James E. Heppelmann

President and CEO

2010 – 2024

Heppelmann served as PTC's CEO for 13 years and spent 26 years total at the company, transforming it from a stagnant CAD vendor into a diversified industrial software platform. He co-founded Windchill Technology in 1997, joined PTC through the Computervision acquisition, and rose through the software division to become CEO in October 2010. His defining decisions included the $112 million ThingWorx acquisition in 2013 that launched PTC into IoT, the $65 million Vuforia acquisition in 2015 that added AR, the $1 billion Rockwell Automation strategic partnership in 2018, the $470 million Onshape acquisition in 2019 that secured cloud-native CAD, and the $1.46 billion ServiceMax acquisition in 2023. Heppelmann also led the subscription transition in 2013-2019 that converted PTC from a perpetual license model to a 92.8% recurring revenue business. Under his leadership, revenue grew from $1.0 billion in 2010 to $2.3 billion in FY2024, and the stock price appreciated significantly. He remained Chairman of the Board after stepping down as CEO in February 2024.

Dick Harrison

President and CEO

2000 – 2024

Harrison became CEO in April 2000 during the most severe crisis in PTC's history, when revenue had declined 14% and the stock had fallen from $25.46 to $8.25. He stabilized the company by restructuring into three business units, discontinuing the failed Netmarkets initiative, and refocusing on core CAD and PLM products. Harrison's defining decision was to persevere with the Pro/ENGINEER product line through the Wildfire release in 2002, which added web-based services and began to address technology obsolescence concerns. He also managed the integration of acquired assets including Computervision and Arbortext. Under Harrison, revenue stabilized in the $800-900 million range, and the company laid the groundwork for Heppelmann's later platform expansion. Harrison stepped down in 2010 after a decade of stabilization.

Steven C. Walske

President and CEO

1986 – 2024

Walske was hired as PTC's president and CEO in December 1986, bringing management discipline and financial rigor that founder Samuel Geisberg, as a mathematician, lacked. Walske held a MBA from Harvard Business School and had been CFO of Computer Corporation of America. He led PTC through its IPO in December 1989, international expansion across Europe and Asia, and revenue growth from $11 million in 1989 to over $900 million by 2000. His defining decision was to develop Pro/ENGINEER simultaneously on multiple UNIX workstation platforms Sun, DEC, Apollo, SGI, and NEC rather than porting from a primary platform, which differentiated PTC from competitors and accelerated market penetration. Walske was replaced by Dick Harrison in April 2000 during the dot-com crisis but remained chairman until June 2000.
