A Decade of Real-Time Feasibility Innovation

Founded in 2016 by architect Clifton Harness and co-founder Ryan Griege, TestFit was established to disrupt the traditionally manual and slow process of architectural feasibility studies. Unlike legacy generative design tools that require complex scripting, TestFit utilizes a "Generate-Edit-Decide" workflow. The platform’s proprietary solver processes actual zoning ordinances, parking ratios, and circulation requirements to produce financially grounded site layouts in seconds. This allows developers to evaluate more than 3,200 deals per week, transforming feasibility from a weeks-long manual task into a live, creative decision-making process.

Strategic Rationale: Aligning Policy with Market Reality

The launch of free access for cities addresses a persistent friction point in urban planning: the disconnect between theoretical zoning and what actually "pencils" for developers. By providing these tools to municipal planning offices, TestFit enables officials to visualize the immediate impact of policy changes, such as upzoning or adjusting parking minimums. This transparency allows for more informed public meetings and faster text amendments. The strategic goal is to foster a collaborative environment where policy reflects the logistical and financial constraints of getting housing built on the ground.

Transformative Analysis: Disrupting the CAD and BIM Lifecycle

TestFit’s market dominance—now used by more than half of the top 10 U.S. multifamily developers—is rooted in its departure from traditional CAD (Computer-Aided Design) foundations. While BIM (Building Information Modeling) is optimized for later-stage construction documentation, TestFit was built specifically for the "messy middle" of early planning. By operating 30 times faster than prior automation approaches, the platform allows teams to explore a wider range of "what if" scenarios. This speed prevents context-switching and keeps stakeholders aligned during the critical moment when capital decisions are made.
