Surveys that learn before they measure

Get answers you can defend

Surventrics tests your questions while your survey runs, so research, product, and insights teams stop shipping surveys that produce data nobody trusts.

Everything you need to defend a finding

Most tools help you collect answers. Surventrics also records how each one was produced \u2014 so when a result is questioned, you have something to point at.

Survey Health CheckFree

Score any survey on bias, length, clarity and accessibility in about a minute — with the specific fixes, not a grade. No account needed.

The TraceFree on every plan

For every response, every question the respondent saw or skipped, and the condition that decided it. When someone challenges a finding, you show them why the data looks the way it does.

Self-optimising

Thompson Sampling moves traffic to the question wording that is working, and mSPRT stopping rules end collection the moment the result is reliable rather than when the calendar says so.

Results you can show your work on

Confidence gating refuses to present a conclusion the sample cannot support, and every instrument reports its own reliability — Cronbach’s α, calibration, attention checks.

Smart branching

Conditional logic that adapts the survey to each respondent — and records what it did, so a branch is never an unexplained gap in your data.

Live analytics

Response rates, completion times, quality scores and variant performance, updating as responses land.

How it works

From creation to insights in four simple steps. Our platform handles the complexity so you can focus on your research.

Step 1

Create Your Survey

Build beautiful, conversational surveys with our intuitive builder. Add multiple question types and smart branching logic.

Step 2

Add Question Variants

Create alternative versions of your questions to test which wording performs best with your audience.

Step 3

Let it optimise

Thompson Sampling shifts traffic towards the wording that is working, and mSPRT stopping rules call it as soon as the result holds up. Reviewed every hour while your survey is live.

Step 4

Get Insights

View comprehensive analytics with quality metrics, completion rates, and actionable insights from your data.

Grounded in proven methodology

Surventrics is built on established research and statistical methods — not guesswork. Here’s what that means in practice.

Adaptive optimization

Every question variant is tested with Thompson Sampling, so traffic shifts toward what works — no weeks of manual A/B analysis.

Research-grade quality

Conclusions stay gated until they're statistically reliable — shared results won't render below a minimum sample, and verdicts are withheld while a survey is still collecting. Cronbach's Alpha and 95% confidence intervals are computed on every survey.

Pre-launch prediction

A calibrated LLM pre-test predicts which of two question wordings will perform better before you spend a single response, so you start with a hypothesis instead of guesswork.

What only Surventrics does

The table stakes — logic, branding, analytics — every serious tool has. These are the capabilities that make your survey optimize itself.
