DOOR3

About DOOR3

DOOR3 has been building software in New York since 2002 and structures engagements explicitly as Advisory, Buildout and Project Rescue. AI Pathfinder, its AI adoption assessment and roadmap, is packaged as a standalone product rather than a discovery phase inside a build, which is rare in this category. ARIA, its second named product, is a set of autonomous agents for law firm workflows.

The record behind it is the deepest of any boutique here: 4.9 from 47 Clutch reviews, with AIG, PepsiCo, Johnson & Johnson, Munich Re and Elsevier named among clients, a $25,000 minimum and $100 to $149 per hour. Clutch records AI consulting at 34% of the service mix, which means the remaining two thirds is still custom development and design, and the firm names no AI model vendor, cloud provider or platform partnership anywhere on its site.

Our verdict

DOOR3 is the most complete boutique purchase in this category for a buyer who wants advice before a build and wants to see who else has bought it. The review base is the second largest here, the client names are checkable enterprise brands, and AI Pathfinder can be bought as an assessment on its own. Two gaps deserve questions. It is a 2002 software consultancy that added AI to an existing practice, with two thirds of its recorded work still development and design, and it names no model vendor, cloud provider or platform partnership anywhere, which is unusual for a firm that leads with agentic AI. No client outcome metrics are published either.
