Booost vs Expandi: same price, two opposite answers to the same fear.

The short answer

Booost Business runs on a machine you own: your LinkedIn session and the IP LinkedIn sees never leave it. It does outreach and content — drafting posts from your sources, publishing under your name or as a Company Page, engaging with them — on top of an intelligence layer that scores your actual network against your goals. €99 per managed account per month, €79 on Basic.

Expandi is a cloud outreach platform that answers the safety question with infrastructure: a dedicated, country-matched IP per account, automatic warm-up and tuned daily limits. $99 per account per month, $79 billed annually.

The prices are close enough to be a coin toss, so price is not the decision here. The decision is whether the machine that acts as you should be yours or theirs — and whether you want the tool to publish as well as prospect.

What Booost does that Expandi does not

Nobody else holds a session to your account. For any cloud tool, Expandi included, the service must be able to act as you while you sleep — which means it holds something that lets it. With Booost the session stays on your disk and your password never reaches us. That is not a claim about how carefully we would guard it: on our side there is nothing to guard. We are precise about the wording, though: "the session stays local" and "the data stays local" are two different promises, and only the first one is ours — the connection graph does travel to our servers, because that is where the intelligence below is computed, and our own documentation says so rather than glossing over it.

It maps the network you already have. Booost scores every contact on six axes — thematic fit, seniority, activity, target fit, influence and proximity — each with the evidence behind it, and shows your network as a graph connected by company, school and shared themes. The Strategy tab tracks an affinity score (0–100) for the people you want in your network: it rises with real interactions and cools with silence, and the app can suggest a warm path through a mutual connection and draft the note. All of it is scored against the goals and target audience you set in a two-minute interview, so "is this person worth my time" is answered against your objectives rather than a generic lead score. Expandi builds campaigns from lists and search results. Nobody in this comparison maps the network you already have — and at the same price, that is a second product's worth of work.

Your IP is not "like yours". It is yours. A dedicated country-matched address is a careful, serious answer to the data-centre problem — better than most of this category offers. It is still an address the vendor assigns. With Booost there is no address to assign: the app runs on the machine you already browse LinkedIn from, and LinkedIn sees the connection you use every day.

It publishes. Booost drafts posts from your own sources, publishes them under your name or as a Company Page, and reacts, comments and reposts around them, in the same workflow as the outreach. Expandi automates outreach and engagement actions. So do Waalaxy, HeyReach, Dripify and lemlist: not one of the five publishes content on LinkedIn. At the same price, one of the two products is doing a second job.

The AI is included flat, and it writes posts. On Pro, model access is part of the subscription — no key to configure, no credit bundles, no tokens to top up. On Basic you bring your own key across 20 providers. Because Booost publishes, its AI writes posts, comments and replies in your voice, in any language.

Built in the EU, GDPR by default, and the desktop app is audited WCAG 2.2 AA.

And Booost Personal is a different product entirely — a browser extension with its own dashboard, for people who want to be present on LinkedIn rather than run campaigns. It reads a post, drafts a comment in your voice in any language, and you publish it. It automates nothing, which is the one compliance claim nobody else in this category can make; it has its own section below. €19–29 per account per month.

Both of us sell safety. Here is the actual difference

Expandi is the most direct competitor Booost has, because it is the only tool here that positions on protecting the account rather than on volume. From its own pages:

"Dedicated country-based IP per account, automatic warm-up, fine-tuned daily limit ranges."

That is a serious answer. A cloud tool logging into your account from a random data centre in another country is asking LinkedIn to notice; a dedicated IP in your own country removes the most obvious signal. Booost takes the other road: there is no IP to assign, because the software runs on your machine and uses your connection.

Which is safer? Nobody has published data, in either direction — not Expandi, not us. Expandi says its limits come from "extensive research and thorough big data analysis" and does not publish the analysis; we would be doing the same thing if we quoted you a number. What you can check is the mechanism: whether a third party holds a live session to your account, and whose connection the requests leave from. Judge us both on that.

"It runs with your machine off" — so does Booost, on hardware you own

Booost Business runs while the machine it is installed on is running, and that machine does not have to be your laptop. Every release ships a Linux .deb and an AppImage next to the Windows and macOS builds, and the licence says you may install it on "any device of your own" — a Debian server for a few euros a month qualifies. Leave it on and campaigns run around the clock, on hardware you control.

For an agency this also closes the IP question in a way a cloud tool cannot: one machine per client is one IP per client, and none of them is rented from us.

One honest gap, documentation rather than architecture: we do not yet publish a step-by-step guide for a headless server, where a desktop application needs a virtual display. It works; the guide is not written yet.

Where Expandi is stronger

1. Nothing to install, and nothing to keep running. No machine to own, no server to think about. For some teams that ends the discussion, and Booost cannot offer it.
2. White-label for agencies. The Agency plan offers white-labelling, role and permission management and a multi-account dashboard, from 10 seats. Booost is multi-account but has no white-label and no roles yet.
3. More campaign shapes out of the box. Expandi advertises 11 campaign types with 19 actions and 11 conditions in a drag-and-drop builder.
4. It is mature. Years in production against a product that opens on 1 September 2026.

Prices, as each company lists them

Currencies are left as each company publishes them; converting them produces a table that goes wrong on its own.

Booost's founding price gives the Pro edition at the Basic price — €79 per account — locked for as long as the subscription stays active: a price that stops moving rather than a discount that expires.

The claim nobody in this category can make — except one

Section 8.2 of LinkedIn's User Agreement prohibits third-party software that automates activity on the platform regardless of where it runs, and names browser extensions explicitly. Cloud tools are covered. Desktop applications are covered. Booost Business is covered, and our Acceptable Use Policy says so in writing rather than in small print.

So neither of us can honestly sell you "LinkedIn-approved automation", and anyone quoting a comparative restriction rate is quoting a feeling rather than published data.

The exception is Booost Personal: it performs no action on LinkedIn at all. It drafts, you publish. There is no automated activity to prohibit — a sentence no cloud platform and no other browser extension can say, because both of them act.

How to choose

If you need to install nothing, or you run many clients from one office under your own brand, Expandi is built for that and Booost is not there yet.

If the account is your own, at the same money, the question becomes what the money buys: a well-protected outreach robot, or a platform that also writes and publishes what your account is known for. That is the comparison, and it is closer than either of us would admit in a headline.

Booost opens on 1 September 2026. Join the waitlist to keep the founding price.
