Loophole

What Loophole does

Loophole is a Denver-based product design, engineering, and prototyping consultancy founded in 2003 by Rob Miller. The firm provides end-to-end industrial design services from concept through engineering for manufacture, including brand ecosystem development, packaging, patent illustration, and design thinking workshops. Its 30+ case-study portfolio spans consumer goods (Thermos Grill2Go, Grippul climbing tools, Brewing America jar lids), medical devices (Aeronics portable oxygen, Spect retinal imaging), IoT/electronics (Goally, Pupptech), outdoor gear (AO Scuba, Trout Scout, Base Buddy), automotive diagnostics (DYVO), and social impact products (Global Water Filter systems deployed in 10+ countries). The core technology stack is traditional industrial design tooling: SolidWorks for CAD modeling, FormZ for 3D architectural visualization, and 3D animation for product rendering.

Loophole serves two primary client segments: startups and new ventures needing full product development support from limited resources, and established brands seeking product line extensions, re-engineering, or market differentiation. Clients include both early-stage companies (Kreddle, BetterBack, Yoee Baby) and major enterprises (General Electric, Thermos). The firm also engages in pro-bono social design work with nonprofits such as Global Access 2030, Conapac, and the Rotary Club of Boulder Flatirons.

Revenue is generated primarily through professional services engagements, with all projects starting on a retainer basis billed at hourly rates on a monthly cadence. Loophole also accepts a limited number of investment or royalty/stock option arrangements that may offset design fees. The company holds multiple granted patents (water filtration, oxygen valve, jar lid, snack snippers, DYVO preloading) and a registered trademark, and operates as a privately held single-owner entity with no external funding or parent company.
