Back
Proto-personas are quick, assumption-based user profiles created at the start of a project to guide early design and development decisions before real user research is conducted.
Why It Matters
- Helps kickstart user-focused thinking from day one.
- Aligns teams on who they think they're building for.
- Provides a foundation to validate (or challenge) during real research.
- Speeds up early design and decision-making processes.
- Reduces the risk of building features with no user value.
Use This Term When...
- You're in the concept or discovery phase of product development.
- You're brainstorming user flows, value propositions, or MVP features.
- You're briefing design or marketing teams early in a project.
- You're planning what user research to prioritise.
- You're testing team assumptions before moving to data-driven personas.
Real-World Example
In one of our projects, we developed multiple proto-personas to represent different segments of our target audience. These quick, assumption-based profiles helped our team stay user-focused during early design sprints and accelerated decision-making before real user data was collected.
Founder Insight
Proto-personas are a starting point — not the final truth. Founders should treat them like hypotheses: useful, but only if tested and improved with real user input.
Key Metrics / Concepts
- Validation Score – How closely proto-personas match real user data post-research.
- Assumption Count – Number of unverified beliefs built into the persona.
- Iteration Frequency – How often proto-personas are reviewed or updated.
- Alignment Level – Team agreement on target user traits.
- Research Priority Flags – Areas identified for further user investigation.
Tools & Technologies
- Miro / FigJam – Ideal for rapid, collaborative proto-persona creation.
- UXPressia – Helps visualise and document evolving personas.
- Google Docs / Slides – Lightweight tools for early team ideation.
What’s Next / Future Trends
AI tools are helping convert proto-personas into research-backed profiles faster. Expect future apps to refine personas in real time based on live behavioural analytics and feedback.
