ReactIn
LinkedIn lead finding from 20+ intent signals, with AI enrichment, ICP filtering and multi-sender outreach campaigns.
From $29/sender/mo 7-day free trial MCP server API
Bottom line
ReactIn is a French LinkedIn prospecting tool that turns intent signals, such as people liking a post or engaging with a competitor, into enriched, AI-filtered lead lists and then runs outreach to them. It suits founders, sales teams and lead generation agencies who run outbound on LinkedIn. Basic starts at $29/sender/mo but leaves out outreach; Growth, the plan most teams need, is $69/sender/mo, and there is a 7-day free trial with no card.
Stands out for: Signal capture, enrichment, AI ICP filtering and LinkedIn sending sit in one product, where many teams use three tools for the same job. It also ships its own MCP server, so you can build lists and draft campaigns from Claude.
Watch out for: The $29 Basic plan does not send messages, so the real entry price for outreach is $69 per LinkedIn account. Automating LinkedIn activity carries account restriction risk whatever the tool, and the reply rate figures on the site are the vendor's own.
Overview
ReactIn is a LinkedIn prospecting platform from ReactIn SAS in France, with an English and French site. It pitches itself as a replacement for a stack of a signal tool, an enrichment tool and a LinkedIn sender, all in one login.
Lead capture runs on 20+ signals: people who like or comment on a post, followers of competitors, visitors to your profile, webinar sign-ups and lead magnet downloads. Templates such as Spyer, Echo, Magnet, Pixel and Scout watch these sources and refresh automatically.
Each lead is enriched on capture with company, job title and contact data, then AI filters tag whether the person is B2B, matches your ICP and is a decision maker. Campaigns branch on whether a lead is already a connection, and replies from every sender land in one inbox.
Up to 8 senders can connect per organization, each capped at a safe daily limit. Webhooks fire on five events, native syncs cover HubSpot, Google Sheets and Airtable, Zapier reaches other apps, and there is a REST API plus an MCP connector for Claude that is included in every plan.
Pricing is per sender. Basic is $29/sender/mo for signals and enrichment only, Growth is $69/sender/mo with outreach, follow-ups, sender rotation and lead management, and Agency is $999/mo for up to 50 senders. All plans start with a 7-day free trial without a card.
Who it's for
Best for
- Lead generation agencies running many LinkedIn accounts
- Founders and SDRs who sell from LinkedIn post engagement

Not ideal for
- Teams that need email as the main outreach channel

Key features
Intent signals. Captures leads from post likes and comments, competitor audiences, profile visits, webinar sign-ups and lead magnet downloads, with auto-refresh on most templates.
AI filtering. Every captured lead is enriched with company, role and contact data, then tagged by AI for B2B, ICP match and decision maker before any message goes out.
Branching campaigns. Campaigns skip the connection request for known contacts and follow up after acceptance for new ones, across up to 8 senders per organization with per-account daily caps.
Claude connector. An MCP server lets you build lists, draft campaigns and triage replies from Claude, with every send shown to you before it goes out.
