Disclosure: we build Prospectio, also European. We rate LGM’s product highly and have tried to say so plainly.
Background
La Growth Machine is a French multichannel outreach platform. You build sequences visually, pick a channel per step across LinkedIn, email and Twitter, and it enriches contacts as it goes. The builder is the nicest in the category by some distance.
Prospectio is a LinkedIn tool. It reads every profile against your ICP and skips poor fits, sends a personalised message in your cloned voice or on video, and has an AI responder reply until the meeting is booked. Email is supported as a step, not as the centre of gravity.

Where La Growth Machine wins
Your campaigns genuinely mix channels. LGM is a multichannel tool that happens to include LinkedIn, and it shows in the design.
You want enrichment and sending in one place. Going from profile to verified email inside the sequence saves an integration and an invoice.
You run complicated flows. Branches and conditions stay readable in LGM where they turn into spaghetti elsewhere.
Where Prospectio wins
LinkedIn is the channel. A LinkedIn-only team on LGM pays for multichannel it will not use, and LinkedIn safety is adequate there rather than the specialism.
Reply rate is the blocker. In our tests, messages of 240 to 420 characters replied at 38.6 percent against 11.2 percent over 700 characters, and a personalised video first touch replied at 40.4 percent against 28.8 percent for text. A better builder does not move those numbers. The message does.
You want fewer wasted sends. Job-title targeting replied at 13.0 percent in our dataset; verified fit replied at 51.9 percent. Prospectio does that check per profile. LGM sends to the list as given.
The honest summary
For a European team running LinkedIn and email together, LGM is one of the easiest tools to recommend. For a team whose pipeline comes from LinkedIn and whose messages are being ignored, the question is not which builder to use, it is who you message and what they get. That is where Prospectio is built to help.
