How it works

From a warm list to a booked call. Four steps, one workspace.

01 · Lists

Start from people who already know you

People who liked, commented on or reposted a post, yours or a competitor's. Or a LinkedIn or Sales Navigator search, a CSV, Apollo or Clay, a Lead Finder list.

02 · Sequences

One sequence, two channels

LinkedIn and email steps in one flow, with conditions, fallbacks and A/B tests. Not accepted? The lead moves to email on its own.

03 · Inbox

Every reply in one inbox

All profiles and mailboxes in one place, with stages, tags, notes for the team and who owns the conversation.

Run it from Claude or your stack

158 MCP tools for Claude, 130+ REST endpoints and webhooks. Ask for a list, a sequence or answers to new replies in plain words.

Account safety

Your profiles are the asset. We treat them that way.

Losing a profile is the fear we hear on almost every demo. So every Grinfi profile works in conditions that keep the risk low, and you see its health at all times.

“We’ve been using it for over six months, and everything runs smoothly and safely. … With many tools causing trouble lately, we haven’t had a single account blocked using Grinfi.”
Anna OchepovskaBusiness Development Manager, Anadea

LinkedIn's terms restrict automated tools, so no tool can promise a profile will never be restricted. We keep the risk low, visible and under your control.

How we protect accounts

What we measured

Who you write to matters more than what you write

Our own Grinfi campaigns over six months: 3,812 invites, one product, the same senders and almost the same copy. Only the list source changed.

Method: 3,812 invites and 1,095 first messages from our own Grinfi campaigns, six months to September 2026. Acceptance counts invites sent, replies count first messages sent.

That is why the system starts from signals and warm lists, and uses cold lists to scale.

Questions about Grinfi

Is it safe for my LinkedIn profiles?

Each profile works from its own cloud browser with its own proxy, only in your working hours, with daily limits recalculated for each profile and a gradual warm-up for new ones. LinkedIn's terms restrict automated tools, so nobody can promise a profile will never be restricted; we keep the risk low and show you each profile's health.

Do I need email, LinkedIn or both?

Either works. Send covers LinkedIn; Enrich and Scale add email inboxes and the multichannel sequencer, so one sequence can move a lead from LinkedIn to email when an invite is not accepted.

How does the trial work?

7 days free, no card needed. Connect a profile, build a list, launch a sequence and see the replies in the inbox.

Where do the lists come from?

People who reacted to a post, LinkedIn and Sales Navigator searches, CSV, Apollo and Clay, the Chrome extension, the API, and lists of decision-makers by portrait from Lead Finder in Telegrin.

Can I run Grinfi from Claude?

Yes. The Grinfi MCP server gives Claude 158 tools: lists, sequences, the inbox, stats. Claude asks you to confirm every action.

What does a seat include?

One LinkedIn profile, the plan's inboxes and its monthly credits for AI, enrichment and email finding. The price per seat drops as you add seats.

Your next meeting is in a list you already have.
