Booost for agencies: every client account in its own session, on a machine you control.

The job

You run LinkedIn for clients who would fire you if their account got restricted. You need several accounts working at once, each behaving like its owner, each posting as its own brand — and you need to explain to a client where their credentials are.

What Booost does for that job

Every client account in its own session, from one installation. Booost Business manages several LinkedIn accounts from one desktop app. Each account signs in inside the app's own browser, in a session isolated from the others and from your personal browsing: no shared cookies, no shared tabs, no tool logged into five clients through one profile. Multi-account management is part of every edition, not an add-on.

Each account warms up and paces itself. The safety system is per account: new accounts start with conservative limits that grow over weeks; actions are spread across the operating hours you set, in that account's time zone; a live trust score slows an account down when its health dips; a circuit breaker pauses it at a CAPTCHA, a rate limit or an odd response; and a sequence stops the instant a prospect replies. A client onboarded today does not inherit the pace of one you have run for a year. There is no plan quota on any of it: the only ceilings are the safety ones, and they are the same on Basic and Pro.

Publish as the client's Company Page. The editorial pipeline drafts posts from sources you choose for that client — feeds, merged across outlets — passes each draft through quality gates (a fact-check against the web, a faithfulness check against the source), queues it for approval, and publishes it under the client's name or as their Company Page, then reacts, comments and reposts around it. Outreach and presence run in the same workflow, per client.

The answer to "where are our credentials?" is: on your machine. Booost signs into LinkedIn from a browser on the computer it is installed on. We never receive a password, and there is no copy of any client's session on a server we control. That is a sentence you can put in a client contract. One precision, because we put it in ours: the connection graph is computed on our servers, so "the session stays local" is the promise and "the data stays local" is only partly true.

Targets and intelligence per client. A two-minute interview per account sets the client's goals and audience; from there, every contact is scored on six axes — thematic fit, seniority, activity, target fit, influence and proximity — with the evidence behind each score, grouped into target clusters, with an affinity score that warms with real interaction and a warm path through a mutual connection when one exists.

No per-user charge, no credits. The price counts LinkedIn accounts, not the people in your agency. Nobody buys a seat to look at a dashboard, and nothing is metered — not actions, not AI on the Pro edition, not the number of installations.

Runs while the machine runs — and the machine can be a server. A desktop app runs while it is on. Every release ships a Linux .deb and an AppImage, and the licence allows installation on any device of your own: a small server left on runs the accounts around the clock. We do not yet publish a step-by-step guide for a headless server; the capability exists and is licensed.

What Booost does not do for agencies — yet

We would rather you read this here than discover it in week two.

• The inbox is per account, not unified. A team answering for ten clients switches between ten inboxes. HeyReach, Salesflow, Meet Alfred and lemlist have a unified inbox; we do not.
• No white-label, no roles and permissions. One workspace, one set of eyes. Expandi, HeyReach, Meet Alfred and Salesflow sell both.
• No native CRM integration, webhook or public API. Export is CSV. Eight of the eleven tools we compare have at least one CRM integration; this is a real gap, not a philosophy.
• No InMail, no group or event campaigns.
• The price is per account and flat. €99 per managed account per month on Pro, €79 on Basic, the same for the first account and the twenty-fifth. At twenty-five accounts that is more than HeyReach ($999 for 25 senders) or Salesflow ($39.95 a seat at 20+), and our comparison pages say so first. If you run that many, read Booost vs HeyReach and Booost vs Salesflow before anything else on this site.

What it costs

Basic is the whole platform with your own AI key, across 20 providers or a local model; Pro adds Booost's managed AI and every workflow node. Billed monthly via Stripe, cancel any time; your clients' data stays on your machine either way. A 30-day trial on the first account for waitlist members.

How to start

Install the app, connect the first client account in the app's browser, answer the interview for that client, and let it warm up. Add the second account when the first one is running. Publish as the client's Company Page from the first week; let outreach reach full pace over the following weeks — that is the point.

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