In-Depth Review: TestFit
What It Is
A real-time real estate feasibility platform that generates design options, unit mixes, and cost modeling in minutes—not weeks.
Who It's For
Developers, architects, and preconstruction teams evaluating deals, layouts, and costs early in the process.
Why It Matters
TestFit replaces slow, manual, error-prone feasibility work with automation that helps teams say yes—or no—faster, saving time, money, and missed opportunity.
Problem Solved
TestFit addresses one of the most painful parts of the development cycle: the early feasibility stage. Typically requiring weeks of back-and-forth between architects and developers just to validate if a site "works," TestFit compresses that to minutes—automating site plans, parking ratios, and financial metrics so teams can evaluate hundreds of schemes and choose the best option fast.
Audience Fit
Primary Users:
- Developers
- Architects
- Preconstruction Managers
- Contractors
- Brokers
- Urban & City Planners
- University real estate teams
Ideal Fit:
- Teams running multiple feasibility studies weekly
- Developer-architect firms
- GC/CMs doing quantity takeoffs during conceptual phases
- National developers scaling across cities and typologies
Key Differentiator
TestFit's real power is in real-time, constraint-aware generation of buildable options. Unlike typical design tools, it factors in zoning, parking, FAR, impervious coverage, and pro forma constraints to output massings and layouts that are actually buildable—and financially viable. That level of automation and data awareness is what makes it more than just a modeling tool.
Workflow Fit
Project Phases Covered:
- Site Acquisition
- Feasibility Analysis
- Concept Design
- Early Financial Modeling
- Schematic Design Prep
Where It Plugs In:
Before you hire an architect. Before a single SketchUp massing. It's the "first pass" tool to validate deals, kill bad ones, and double down on the right opportunities.
User Experience
Speed: Instant. You can test hundreds of layouts and deal models in hours.
Interface: Clean, powerful, and spreadsheet-integrated for real-world KPIs.
Learning Curve: Medium—teams get onboarded in days.
Collaboration: Great for developers and consultants to align before design kicks off.
Integrations: Revit, CAD, SketchUp, and map-layer support.
Bonus Insight
TestFit isn't just about saying "yes"—it's about getting to a smart "no" fast. In a market where underwriting 100+ sites to find 10 viable ones is common, tools that cut wasted time and increase iteration speed provide immediate ROI. Many users report 4–10x faster feasibility cycles—and some win deals simply by using TestFit as a differentiator.
Real Users Say
"Before TestFit, it was 3–4 weeks per site. Now, 10 minutes."
"We've won $750K in fees using TestFit as our edge."
"It's how we build trust between developers and city planners."
