BlockSurvey is a privacy-first, AI-powered survey platform that lets teams create, distribute, and analyze end-to-end encrypted surveys while retaining full ownership of response data.
About
BlockSurvey is an online survey and form platform built around two commitments: data privacy and respondent anonymity. Conventional survey tools store responses on the vendor's servers, where the provider can technically read them; BlockSurvey instead applies end-to-end encryption so that only the survey owner can view the collected answers. This matters for teams gathering sensitive feedback, such as patient experiences, employee opinions, or confidential research data, where trust directly affects how honestly people respond.
The product works as a full survey lifecycle tool: users build questionnaires with AI assistance, distribute them to respondents, and analyze results with automated AI insights. It offers standard question types (NPS, matrix tables, rank order, file upload), survey logic, white-label branding, and integrations with tools such as Slack, Google Sheets, HubSpot, and Power BI. BlockSurvey states that it serves teams in more than 50 countries and holds SOC 2, ISO 27001, HIPAA, and GDPR certifications.
