openPetition supports petitioners in creating their petitions, collecting signatures, and submitting the petitions to the appropriate recipient.  It helps citizens address their concerns to their political representatives through online participation.

openPetition advises and supports petitioners to maximize the impact of all openPetitions and developed the "constituency radar" to ensures that politicians know what moves citizens in their constituency.  When a petition reaches the openPetition quorum specified by the petitioner, the relevant public officials are asked for a statement.

openPetition is modernizing parliamentary democracy, brings petitions to parliaments across Europe, and advocates politically for a more effective petition system.
