Becomes clear after question 1
Upvoice puts one question to everyone at once. People join in live and anonymously, 8 to 10,000 at a time. Within an hour you know which direction has support.
This is how a moderator sees a session about collaboration unfold. Messages come in, votes are collected and the themes take shape for each question. Every dot is one message; the bigger it is, the more votes it has.

For each of these moments you sharpen one question, everyone joins in live and you see which next step has support.
The survey results are in, but the why is missing. One dialogue around the key scores delivers a prioritised action list.
A reorganisation, merger or measure has to land. Gauge the concerns before you break the news, and again afterwards.
An anonymous dialogue about topics people do not discuss out loud. With reporting for the board, HR and the works council.
There is a plan on the table. Test where the support is and which objections you need to take seriously.
A strategy only works when people understand it and dare to question it. Let teams and layers respond to it.
Hear large groups in one hour and make visible where they differ and which direction gets support.
Do not wait for signals to escalate. A fixed dialogue calendar lets leadership hear periodically what is changing.
What happens for you as the client, from the question to the synthesis. Your people only need a link: no account, no download.
You decide what you need your people's input on and how you involve them in the substance. Together we choose the questions you ask in the dialogue.
Everyone takes part live and anonymously, in one session of 45 to 75 minutes. Participants vote on each other's messages, so the ideas with the most support rise to the top on their own.
You see the main themes during the session itself. Afterwards an automatic synthesis follows, with the main line and the nuances within it.

If you hold dialogues often, you work on Upvoice yourself with a licence. For a single project, choose full service.
Your team runs sessions itself, whenever needed. We train your team and run the first session together.
From sharpening your question to a report the organisation can act on. What you mainly provide is the substance.

Gasunie, ANWB and UMCG put a question to hundreds to thousands of people. Read what each case delivered.
Upvoice is built on 25 years of pioneering work by Synthetron in anonymous group dialogue. Boards, municipalities, healthcare and education now use it to hear their people.
Directors, advisers and project leaders on what happens when a large group gets to weigh in.
‘Synthetron helped us in a highly professional way to reach more than 6,000 members in online conversations about the key issues of the road-pricing proposal.’
‘Synthetron has made collaboration and people management so simple and easy for us.’
‘Dare to try new things, as we did by opening up topics that are sometimes taboo. It works!’
‘Organise conversations like these! People enjoy talking to each other and reflect on themselves as a result, but they also learn from each other.’
Is your question not listed? Ask it in an introductory call and we will go through it together.
Every written message is rated by other participants. A message first goes to four others; with a lot of support it spreads step by step to the rest. That way participants' messages become the answer options that others vote on. That gives you a fuller picture than separate open questions.
Almost every dialogue touches on things people do not easily say out loud in a group, because they are critical, controversial or simply feel awkward. We know from experience that anonymity increases both the honesty and the depth of the conversation.
Yes. Everyone takes part in their own language. Thanks to real-time translation we work with more than 120 languages, even mixed together in a single session.
A dialogue makes sense once a group no longer fits in one meeting room. For sensitive topics, for example within a team, the dialogue is a safe place to speak freely, and it works from 8 people. At the upper end, up to 10,000 people take part at once.
Upvoice stores no personal data. Every participant gets a random code; a single functional cookie keeps the session together.
Yes. Every participant gets a random code instead of a name. Nobody can trace a message back to a person, not even us. Reporting per segment only happens for groups of at least eight people.
In two ways. With a licence you work on Upvoice yourself, a product of Synthetron NV: we train your team and run the first session together. For a single project, choose full service and we take care of everything. Your participants only need a link.
That depends on how often you run a dialogue, with how many people and how much guidance you want. With a licence, the cost per session is lower than with separate projects. After an introductory call you get a tailored proposal.
In a demo you see Upvoice with your own question: what you ask, who you invite and what you'll have at the end.
