pol-probe

A Proof of Life (PoL) probe is a lightweight, disposable validation experiment used to test hypotheses and eliminate risks before investing in expensive MVP development.

You validate a product hypothesis before building an MVP by defining a lightweight Proof of Life probe that matches a specific validation method to your learning goal and success criteria.

You can choose from five validation experiment flavors for risk assessment: Feasibility, Task-Focused, Narrative, Synthetic Data, and Vibe-Coded probes, each matching specific learning goals.

Use a Task-Focused Test probe for prototyping when you need to verify if users can complete a core workflow with a simple prototype, ensuring the fundamental user journey is viable.

Lean startup validation does not require a working prototype; you can use Narrative or Synthetic Data probes to test feasibility and de-risk product decisions without any coded implementation.

Choose the right probe flavor for product hypothesis testing by matching the validation method to your specific learning goal, selecting from Feasibility, Task-Focused, Narrative, Synthetic Data, or Vibe-Coded approaches.
