SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Identify and rank startup assumptions by risk to guide validation and prioritization of RATs.

Core Features & Use Cases

Discovery and ranking of implicit assumptions from strategy artifacts (PR/FAQ, Lean Canvas, startup context).
Identification of Riskiest Assumption (RAT) per category: Desirability, Viability, Feasibility.
Guidance to design fast, low-cost experiments to validate top RATs.
Use cases: teams map assumptions and plan validation before product development.

Quick Start

Provide your PR/FAQ and Lean Canvas artifacts to generate the assumption map.

FAQPage Schema

How do I identify and rank startup assumptions by risk from a Lean Canvas?▼

To rank startup assumptions by risk, feed your Lean Canvas and PR/FAQ into the assumption mapping process. It extracts implicit strategy assumptions and prioritizes them by risk to focus validation efforts before development.

What is a Riskiest Assumption Test (RAT) and how do I find my RATs?▼

A Riskiest Assumption Test (RAT) targets the most critical uncertainties across desirability, viability, and feasibility. You find RATs by mapping assumptions from startup context and ranking them to isolate what threatens your strategy most.

How do I design fast experiments to validate startup assumptions?▼

You can design fast validation experiments by first categorizing your assumptions into desirability, viability, and feasibility risks. Once the RAT is identified, the process outputs structured experiment designs to test it cheaply.

Can I use PR/FAQ artifacts to map assumptions for product validation?▼

Yes, PR/FAQ artifacts are explicitly supported inputs for assumption mapping. The process analyzes your PR/FAQ alongside startup context to surface implicit assumptions and produce a structured assumption map for validation.

When do I need to map startup assumptions before product development?▼

You need to map startup assumptions before product development when you must prioritize validation and mitigate strategy risks. It helps product teams identify RATs early to avoid building features based on untested viability or desirability beliefs.
