The short version
- What it is
- A cloud tool that chains LinkedIn, email and X steps in one sequence, with a company database and enrichment credits built in. Made by B3 SAS in Saint-Mandé (Paris).
- How it bills
- Per identity, meaning one sender: their LinkedIn account and 1 to 10 of their own email addresses. €60, €120 or €180 per identity per month, less on yearly billing. See the full pricing.
- Who it suits
- B2B companies of 10 to 200 employees with a sales team of at least 3, according to La Growth Machine's affiliate programme, especially when LinkedIn leads the sequence.
La Growth Machine features: LinkedIn, email, X and call tasks in one sequence
Every step of a sequence can run on a different channel, and a step can wait for what happened before, such as an accepted invitation. What changes from one plan to the next is which channels and tools you get, and even that is not stated the same way everywhere: custom sequences start at Pro according to its plan card and comparison table, at Ultimate according to the FAQ, on every paid plan according to the features page.
Profile visits, invitations with a note, messages, voice messages, likes and follows, run from the cloud.
All plansGmail, Outlook or SMTP, follow-ups in the same thread, open and click tracking with a custom tracking domain. 1 sending address per identity on Basic, 5 on Pro, 10 on Ultimate.
All plansX (Twitter)
Follow, like, retweet and post. The plan cards reserve X for Ultimate, but the comparison table on the same page ticks it for all three plans: check with La Growth Machine before relying on it.
Ultimate (cards)Call tasks
Manual call reminders inside the sequence. Aircall and Ringover connect as integrations; no built-in dialer was found.
From ProMultichannel inbox
LinkedIn and email replies in one place. The plan cards and table start it at Pro; the feature page says it is included in all plans.
From ProTeam
Members who do not send are free (3 on Basic, 25 on Pro, according to the plan cards), but there is no permission management: a member sees everything. Separate workspaces carry no fee of their own, but each one needs its own subscription.
LinkedIn automation at La Growth Machine: AI voice messages, Real Chat Mode and daily limits
Voice messages, recorded or generated
La Growth Machine can drop a voice message into a LinkedIn conversation, either one you recorded or an AI voice that opens with a personalised intro. Voice messages last 1 minute at most and only reach first-degree connections, so they come after the invitation is accepted. That is a feature Emelia does not list.
Real Chat Mode
Real Chat Mode splits a LinkedIn message into several short ones, the way people actually type. Its help article reserves it for "Pro, Ultimate and Business"; there is no Business plan on the pricing page, so read that as Pro and Ultimate.
Daily limits per identity
For an established LinkedIn account, La Growth Machine's help center recommends up to 80 profile visits, 80 invitations and 120 messages a day. A recent account starts at 40 a day and climbs by 10 at each step. The same help center puts LinkedIn's own invitation ceiling at 150 to 250 a week, which a full week at 80 a day would exceed: treat the daily figure as a ceiling, not a target.
On a free LinkedIn account, invitations with a personal note are capped by LinkedIn itself; La Growth Machine's help articles give different monthly figures for that cap (3, 5 and 10).
Account safety
Campaigns run in the cloud through dedicated 5G mobile proxies, not from your browser. When LinkedIn shows a first sign of blocking, La Growth Machine slows the identity's actions for 24 hours, and it waits 30 minutes after an accepted invitation before the next step.
La Growth Machine HubSpot integration: Ultimate only, 1 CRM per workspace
The native CRM sync (HubSpot or Pipedrive) comes with Ultimate, the top plan, at €180 per identity per month. On HubSpot it now works both ways, field by field, with activities and contact owners, and La Growth Machine can create HubSpot call tasks. A workspace connects to 1 native CRM at a time.
Salesforce is not natively integrated, according to the help center: it goes through Zapier. Some of La Growth Machine's own marketing says otherwise, so ask before you buy if Salesforce matters.
The API, Zapier, Make and Clay start at Pro; Basic has none of them, nor PhantomBuster. The integrations page also lists n8n, Slack, Apify, Aircall, Ringover and several data providers. At Emelia, a CRM integration is part of every plan (one CRM on Start and Grow, several on Scale).
La Growth Machine API documentation, webhooks and MCP server
The API key sits in the app and the documentation is published on Postman. The API creates, stops and deletes a lead, marks it as converted, builds an audience from a LinkedIn search URL and returns campaign statistics. It is available from Pro, with unlimited webhooks; Basic has no API.
La Growth Machine also runs an MCP server (mcp.lagrowthmachine.com) for Claude, ChatGPT, Codex, Cursor and n8n, and publishes a library of Claude skills to drive campaigns from an AI assistant.
Cold email from La Growth Machine: one person’s addresses, no built-in warm-up
Each identity sends from its own addresses: 1 on Basic, up to 5 on Pro and 10 on Ultimate, used in rotation. The terms only allow variants of the same sender's name on that identity, so extra addresses do not add extra senders. What an identity covers is detailed on the pricing page.
La Growth Machine's help center suggests 100 to 250 prospecting emails per mailbox per day, never more than 250. That is a high pace for cold email: spreading the volume over more mailboxes is the usual way to protect deliverability, which is why the number of mailboxes matters.
There is no built-in warm-up. The help center points to MailWarm or MailReach, which you pay separately, and La Growth Machine's own comparison page against lemlist marks warm-up as missing. Emelia includes warm-up in every plan, with 3 mailboxes on Start, 50 on Grow and unlimited on Scale, counted per plan for the whole team.
Finding leads: the La Growth Machine database, lookalike search and Signals
LGM Database lists 27M+ companies, searchable in plain language, with the contacts who work there. Browsing it costs no credits. Lookalike search returns up to 25 similar companies per search, 500 on Ultimate (another article quotes 500 without that restriction).
Signals imports people automatically when something happens: a job change, a like or comment on a post, an event sign-up, a visit to your website. The Chrome extension, still in beta, captures a LinkedIn profile, enriches it and adds it to an audience.
Enrichment is paid in credits: 5 for a verified email (a cascade of 9 providers), 1 for LinkedIn data, 20 for a mobile number, charged only when a number is found. Each plan includes a monthly allowance; the pricing page explains what it covers. Emelia has no built-in database: its finder, verifier and phone finder work on the leads you bring.
Total€180/month
- 3 LinkedIn accounts
- 50 mailboxes
- Warm-up included
Total€97/month
3 reps, 3 identities: what the same team costs on Emelia
Take 3 sales reps who each prospect on LinkedIn and send cold emails from one mailbox. On La Growth Machine that is 3 identities on Basic, the most Basic accepts: €180 a month, or €150 a month billed yearly.
On Emelia, the Grow plan covers 3 LinkedIn accounts and 50 mailboxes: €97 a month, or €80.83 a month billed yearly. Billed monthly, Start plus 2 extra LinkedIn accounts at €29 also covers this team, for €95 a month. One more rep would not fit on Basic, which stops at 3 identities: the next plan, Pro, costs €120 per identity.
What the La Growth Machine bill includes and Emelia's does not: the company database, lookalike search and 1,250 enrichment credits per identity each month on Basic. Weigh those against the gap before deciding.
La Growth Machine reviews: 4.9/5 on Capterra, 4.3/5 on Trustpilot
La Growth Machine displays several scores of its own: 4.9/5 on its homepage next to what looks like a G2 logo, 4.6/5 from "427 reviews" on its customers page, and 4.8/5 from 500 in its structured data. Here is what the review sites show. G2 blocks automated access, so we do not report a G2 score. The most recent Capterra review dates from December 18, 2024, and the Trustpilot profile is not claimed by La Growth Machine.
What reviewers praise
- Multichannel sequences (LinkedIn, email, X) that are easy to build
- A clear interface
- Responsive, human support
- Automatic enrichment and CRM sync
- LinkedIn voice messages
What reviewers criticise
- The price, with useful features kept for the higher plans
- Bugs: sends outside the schedule, webhooks, email threads, sync
- Daily limits not always respected
- One mailbox per sender on the entry plan, built for modest volumes
Since 2017 or 2019? The company behind La Growth Machine
La Growth Machine's homepage says it has been "safely automating LinkedIn since 2017". The company that sells it, B3 SAS, based in Saint-Mandé (Paris), was registered on October 30, 2019, and its About page dates the launch to 2019. The product grew out of an outbound agency founded by Brice Maurin (deux.io, according to a La Growth Machine article).
It is run by its three founders: Brice Maurin (CEO), Adrien Moreau-Camard (COO) and Boris Tchangang (CTO). The company describes itself as self-financed, and the French business register puts its headcount at 20 to 49 employees. Support is run in-house, in France, and the contract falls under French law.
Its customer count depends on the page: "10,000+ GTM teams" on the homepage and About page, "25,000+ users" on the customers page. Over the past twelve months, the About page reports 12,536 campaigns created and 9,379 launched.
Login, website, extension, safety: La Growth Machine questions
Through the web app at app.lagrowthmachine.com/login. Campaigns then run in La Growth Machine's cloud, so they keep going when your browser is closed.

Yes, in beta. It captures a LinkedIn profile you are viewing, enriches it and adds it to an audience. Campaigns themselves run in the cloud, not in the extension. Emelia's Chrome extension starts from a Sales Navigator search: its Export with Emelia button sends your search to Emelia, which extracts the leads, ready to add to a campaign (how it works).
Signals, which imports leads automatically on buying signals, was announced in April 2026. A September 2026 roundup of the summer's releases lists mobile number search, two-way HubSpot sync, the MCP server for Claude and ChatGPT, and the Chrome extension (in beta).
On Capterra, yes: 4.9/5 from 45 reviews, the latest dated December 18, 2024. Trustpilot shows 4.3/5 from 30 reviews. The 4.9/5 badge on La Growth Machine's homepage sits next to what looks like a G2 logo, which we could not check.
It reduces the risk without removing it: cloud sending through dedicated mobile proxies, daily ceilings per identity, an automatic 24-hour slowdown at the first sign of blocking. LinkedIn's own weekly invitation limit still applies.
Yes: 14 days without a credit card, with 1 identity and without mobile number search. The account is deactivated at the end; it does not switch to a paid plan by itself.
Emelia is a La Growth Machine competitor. We have tried to stay fair: every figure about La Growth Machine comes from its own website or public review sites.
