Launch your first B2B prospecting campaign in 15 minutes, data included.

murmur (murmur.ad) is a French B2B prospecting platform that writes each target business a message personalised from its own website and submits it through the contact form that business publishes. You pick your targets from a database of 46 million businesses in 164 countries, approve sample messages, and replies come back sorted in your workspace. Not cold email, not LinkedIn automation, not a CRM: the platform is open for prospecting in France, with your first 600 contacts free and no credit card.

murmur submits your message through the contact form the business publishes on its own website, under your name and with your reply address. Each message carries your identity, so the business knows who is writing and can answer you directly. Replies go to the address you chose; you can also forward them to murmur to have them sorted in your workspace.

Businesses that sell to other businesses. Founders who still do the selling, small and mid-sized businesses prospecting alongside their day-to-day work, sales teams and business developers (SDRs, BDRs) who want to spend their time on conversations, and freelancers and consultants. Prospecting, growth and marketing agencies working for several clients have access to a multi-client plan, priced by custom quote.

In a go-to-market (GTM) strategy, as in a simple prospecting plan, murmur handles the first-contact stage. You define your offer and your ideal customer profile (ICP); murmur can also suggest profiles from your website. You see how many businesses matching that profile you can reach, then murmur adapts your message to each one and submits it through its contact form. Replies come back sorted; the rest of the sales cycle stays with you.

murmur adds to them rather than replacing them: it is one more outbound prospecting channel. It goes through the contact form each business publishes on its website, with no domains or sending mailboxes to set up. There is no list to buy and no LinkedIn account involved. Your emails, LinkedIn messages and calls can carry on alongside: murmur doesn’t run them.

No. You can search murmur’s database by activity and location. If you already have a list of websites, you can start from that too.

murmur uses each business’s website to write an opening related to their activity. Your offer, instructions and signature remain the foundation. You review examples before messages are sent.

In your campaign workspace, sorted automatically, once your campaign’s reply address is forwarded to murmur; murmur guides you through setting that up. Without forwarding, replies simply reach your reply address as usual. You then take over the conversation with the businesses that are interested.

Create your account and launch your first campaign: your first 600 contacts are free, follow-up included, no credit card required, and during the launch offer the trial has no time limit. Plans and credit prices are listed on the Pricing page; murmur agency is priced by custom quote.

It comes from public sources, including business websites, directories and company registers. Available information varies by country and profile.

On the platform, France is open today and the United Kingdom will be the next country. To prospect elsewhere, murmur agency runs your campaigns internationally. The database covers 164 countries, but prospecting rules change from one country to the next: in some, such as Germany or Italy, electronic prospecting requires prior consent, even between businesses, and murmur does not send there without it. Your message is written in the recipient’s language.

A send that isn’t proven is not charged. Credit and billing conditions are available on the Pricing page.

Yes. Every message sent from murmur includes a way to opt out of further contact, and an opt-out applies across all murmur clients, not only the one that sent the message. A public page also lets any business ask not to be contacted again by murmur’s clients, after confirming the request from an address on its own domain.

If growth hacking means testing an acquisition channel quickly and measuring what it brings, yes: a target, a message scored by the coach, examples approved before sending, then sorted replies. But nothing in it relies on tricks: no list to buy, sending rules applied country by country, and a way to opt out in every message sent from murmur. No result is promised either: what you get depends on your offer and your target.

Yes, with murmur agency: our team prepares and runs your campaigns, including internationally. You approve the targeting and messages, then take over the replies. This offer is priced by custom quote.
