VENTURE BUILDING · 02FREE TOOLKIT
Make the business case visible and testable.
Intrax Tools
Three compact tools for three early venture questions.
Market Sizing checks whether the opportunity is large and reachable enough. Financial Model tests the operating logic. Pitch Narrative organizes the evidence, assumptions and ask into a coherent discussion.
A transparent top-down starting point. Replace every assumption with a source before using it in a decision.
What the toolkit does
It creates a working hypothesis—not false certainty.
The outputs are intended to make assumptions explicit, expose missing evidence and improve the next conversation. They are useful for early exploration, internal planning and preparing a more focused validation step.
The toolkit does not replace customer interviews, professional financial advice, legal review or a complete investment process. Revisit the assumptions whenever real evidence changes the picture.
