## Grounded in public survey data, not guesswork

The US panel is calibrated on public survey data: demographics, attitudes and vote patterns. Each persona carries the variables it was built from, so an answer can always be traced back to the population it stands for.

## Before you run your first survey

Four short guides, no account needed: what a study costs, how long it takes, what the free plan settles, and how many responses a figure needs.

### [What it costs](/us/cost-of-market-research)

From $0 to $349 a month, and what drives the bill on a fielded study.

### [How long it takes](/us/how-long-does-market-research-take)

Minutes per run, under 48 hours end to end, and what replaces weeks of field time.

### [Without a budget](/us/market-research-without-a-budget)

Five surveys a month, 25 personas each, and the questions that settle at $0.

### [Sample size calculator](/us/sample-size-calculator)

How many responses a margin of error actually requires.
