La Growth Machine

La Growth Machine is sales engagement software that runs B2B outreach sequences across LinkedIn, email, calls and X, priced per sending identity.

La Growth Machine works each B2B prospect through a planned series of touches on LinkedIn, email, phone and X, and stops once the lead replies. Teams turn to it when one channel alone no longer fills the pipeline. The same tool finds and enriches the leads, drafts the messages and collects the answers. B3, an independent French company with its registered office in Saint-Mandé, launched it in 2019 as a product and a company of its own. Campaigns take shape in the sequence builder. LinkedIn connection requests, AI-generated voice messages, email follow-ups, X messages and call tasks sit on one timeline with delays and conditions. Leads come from the LGM Database through ABM queries, or from LinkedIn intent data such as post likers, commenters and event attendees. Signals add leads automatically after a job change, a key page visit or a form submission. Waterfall enrichment searches several providers for a verified email, and phone numbers can be enriched on credits. The AI Copywriting Assistant drafts or rewrites each message, A/B testing compares two variants, and a rotating inbox spreads sending over several addresses. Replies from every channel land in a unified inbox, with results reported for each action and channel. Founders starting outbound, sales teams scaling multichannel prospecting and lead generation agencies are the people it is built for. RevOps, SalesOps and growth teams adopt it when outreach has to follow a set process rather than each rep's habits. Pricing is per identity, meaning each person whose LinkedIn and email accounts send the messages, with Basic and Pro billed annually by default and Ultimate quoted. Agencies have a plan of their own with a minimum number of identities, and a Custom plan lets a team pick features and limits with sales. A trial without a card lets a team run a first campaign before paying. A campaign usually begins with a list pulled from LinkedIn or a CRM, enriched with emails, then enrolled in a sequence that alternates a connection request, a voice message and an email. When a lead answers, the sequence halts and the rep takes the thread from the inbox. On the top plan, sent and replied messages are written back to HubSpot or Pipedrive, so the CRM keeps the record of each conversation. Teams that already shape their lead data in Clay, or route it through Zapier or Make, feed contacts in from there. La Growth Machine fits sales teams whose prospects are easier to reach on LinkedIn than by cold email alone.
