Descriptiontext

ProtoFab, Inc. is a family-owned precision CNC machining and contract manufacturing company founded in 1998, headquartered in Petaluma, California. The company operates from a single 20,000+ square foot ISO 9001:2015 registered, ITAR registered facility and delivers prototype-to-production services including 3, 4, and 5-axis milling, 7-axis Swiss screw machining, prototyping with DFM support, manufacturing with product lifecycle management, metrology via two Zeiss-equipped inspection labs, and finishing services. Its technological core centers on capital-intensive equipment (KERN Micro Vario 5-axis center with 50,000 RPM spindle, Erowa ER-061000 automation, Kuka KR 6 R900 robotics, Zeiss Micura/Contura/Duramax CMMs with Vast scanning probes) and a 24/7 lights-out manufacturing system capable of producing up to 250,000 parts per week across metals (Titanium, Inconel, Aluminum, Stainless Steel) and plastics (PEEK).

The company serves four primary enterprise verticals: aerospace/satellite, medical devices, telecommunications, and commercial/industrial. Its customer base uses ProtoFab parts in mission-critical applications including flight-critical hardware, antenna structures, RF waveguides, surgical instruments, implants, and 5G/satellite communication components. Go-to-market is exclusively direct enterprise sales (phone and email quote-based engagement) supplemented by active participation in industry trade shows including DMEMS, Design-2-Part Show, MD&M West, Space Tech Expo USA, Northwest Machine Tool Expo, AEMS, and Boombastic 2025. The company is currently pursuing AS9100D aerospace certification to formally expand its addressable market within aerospace and defense.

Revenue is generated through project-based, quote-driven custom machining contracts with multi-year engagements typical of mission-critical component supply. There are no disclosed pricing tiers, no published revenue figures, no external funding rounds, no M&A activity, and no parent company or institutional investors. Ownership and control remain with the founding family under President and Founder Mike Maendl, with Rich Parchman as General Manager. The company claims global service reach from its single Northern California site, serving customers whose parts fly in satellites, aircraft, and communication systems worldwide.
