Assembley vs Helios Voting

Assembley is web software for organisations running general assemblies and member votes. It covers invitations, attendance registration, agenda management, and vote recording for online, in-person, and hybrid meetings. Organisers can offer Yes, No, or Abstain voting, secret ballots, board elections, and split voting, while tracking live results and quorum. Voters receive single-use ballot links and can participate without an account, password, or app. Organisations can upload shareholder or member registers as CSV files; Assembley checks them for duplicates and errors. Its evidence package brings together the event chain, Merkle roots, attendance, and results for independent verification. Assembley says votes are write-once at the database level, with hash-chained event logs and Merkle roots supporting auditability. Its database and application run in Frankfurt, Germany, while transactional mail is sent from Ireland; two sub-processor agreements specify primary processing in the United States. It says it processes data under GDPR and provides a Data Processing Agreement on paid plans, but holds no third-party security certification. Starter is free forever; Basic costs €149/ yr.
