Design from human truth.
A methodology for connecting what people genuinely need to the products, experiences, and technologies we create.
The Method
Seven stages from truth to technology
HTDD establishes a traceable relationship between human understanding and technological implementation. This progression is fundamental—each stage emerges from the previous one.
Founder Experience
The lived experience and observations of the founder or founding team.
Human Truth
A distilled understanding of how people genuinely think, feel, or behave in relation to the problem.
Product Principle
A strategic principle about what the product should be or do, grounded in human truth.
Experience Principle
A principle defining the kind of experience we want to create for the user.
Interaction Principle
A principle governing how the user interacts with the product or feature.
Interface
The specific UI elements and layout that embody the interaction principle.
Technology
The implementation, infrastructure, and technical decisions that enable the interface.
The Platform
HTDD Core
Your product tools remember what you're building. HTDD Core remembers why.
The commercial platform helps organizations operationalize the methodology through evidence tracking, principle governance, and decision traceability.
