Short answers
- What is the difference between Vouch and Strella?
- Strella: A professional research platform that writes interview guides, runs AI-moderated interviews with dynamic probing, records video, synthesises across participants, builds highlight reels, and recruits from a large panel. Vouch is a validation workspace for a pre-launch idea — it ranks the assumptions that could kill it, coaches you live during customer interviews, scores the evidence against each assumption, and ends in a paid pilot ask.
- Who should use Strella?
- Pick Strella if you're a research or product team running structured studies at scale and need panel recruitment and polished deliverables.
- Who should use Vouch?
- Pick Vouch if you're validating an idea before building it and need a defensible go/pivot call, not a research programme.
What Strella does well
- Genuinely sophisticated moderation and synthesis — built for research teams running studies at scale.
- Panel recruitment solves the hardest logistics problem in research.
- Highlight reels are persuasive artefacts for internal stakeholders.
Where it stops short
- Priced and scoped for research teams, not a founder testing whether an idea deserves to exist.
- Study-shaped work has a setup cost that doesn't fit 'I had an idea on Sunday'.
- Recruited panellists are not your buyers. For a niche B2B idea, ten people who actually hold the budget beat a hundred matched panellists.
What Vouch does differently
Built for the pre-product moment: one idea, ranked assumptions, ten conversations, a decision.
No study design required — the first risk check takes about two minutes.
Evidence framed as a founder decision, not a research report.
