murmur is a B2B prospecting platform that personalises each message with AI and submits it through the contact form published on the company's website. Its website is murmur.ad. It is run by MURMUR SAS, a French simplified joint-stock company registered with the Paris Trade and Companies Register (RCS) under number 108 784 521, with its registered office at 8 bis rue Abel, 75012 Paris.
Why murmur exists
The first sales contact takes more and more effort for fewer and fewer replies. Yet millions of businesses publish a contact form on their own website: it is the channel they chose to be written to. As of 26 October 2026, murmur had analysed 24,388,970 business websites and confirmed a contact form on 4,689,755 of them, about 19%.
Before it opened as a self-service platform, in 2026, murmur was a contact form prospecting service run by hand by the team, for real clients. The platform turns that work into self-service: choose the businesses, write the message, adapt it to each website, submit it, follow the replies. The service run by the team continues as murmur agency, on custom quote, including for prospecting abroad.

The database is not a right to send: how many businesses you can reach depends on your target, whether each business has a contact form, and each country's rules. Messages are written in the recipient's language.
What murmur is not
- Not a CRM.
- Not an email marketing tool.
- Not a LinkedIn automation tool.
- Not a domain warm-up tool.
- Not a seller of leads or meetings: murmur opens conversations, and the businesses that reply with interest become your leads.
- Not an autonomous AI SDR: you choose the target, and you approve the message and examples before anything is sent.
Not to be confused with
murmur (murmur.ad) has no connection with these organisations and projects of the same name.

Our commitments
- An objection applies across all our clients. A business that no longer wants to be contacted says so on the Stop being contacted page, with an email address on its own domain. It confirms through the link it receives, valid for 48 hours. The objection then applies to every murmur client.
- Charged on proof of sending. Credits are only charged on proof of sending: a message whose delivery is not established is not billed.
- No prospecting without consent where the law requires it. In countries that require prior consent, including Germany, Austria, Denmark, Spain and Italy, murmur does not prospect without documented consent. Our reading, country by country: Prospecting rules.
- One message written for each business. murmur reads the business's website and adapts the message to what it does. You review examples before anything is sent.
- No result promised. murmur sells neither leads nor meetings.
