The product creates and refines survey questions from prompts, then provides thematic, sentiment, and summary analysis. It supports email, SMS, links, QR codes, and embeds.

Where it sits in the data

BlockSurvey's $15K a month is higher than 71% of the 6,604 projects with founder-reported monthly revenue in our dataset; the median across them is $2K. Snapshot: 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

In my view, this needs real work because the buyer has to trust the product with survey responses and sensitive research data. The buyer may be an individual, a research team, or an organization, so the product must make privacy and answer protection central to the experience.

Distribution would need to come from useful research resources, product integrations, and direct demonstrations. Building the survey editor, conversational interviews, analysis, encryption, integrations, and support would create substantial product and operational work.

Verdict: Needs real work.

One thing to take from it

BlockSurvey combines AI-assisted survey creation and analysis with encrypted responses, multiple distribution formats, and integrations with tools including Excel, Airtable, HubSpot, and Power BI.
